1) Overview
This User's Guide covers the stand-alone desktop version of the MDDF Tool for Avails validation
and translation. A web-based version of these tools is also available at https://mddf.movielabs.com/services.
1.1) Functionality
The
Validator
is a standalone application that is intended to be used during the pre-processing of an Avails Metadata file.
Capabilities include:
- Validates that one or more Avails files are in conformance with the Avails
specification.
- Validation of Avails file in either XML or XLSX format.
- Optional checks for conformance with applicable best practices or similar
guidance.
- Integrated XML Editor with linkage to any errors or warnings detected.
- Conversion of XLSX formatted Avails into XML.
- Conversion of XML formatted Avails into XLSX.
- Ability to run in a scripted mode for batch processing of multiple files.
- Ability to run as either a native binary )installers for Windows, Mac OSX, and Linux
platforms) or as an executable Java jar.
1.2) User Interface
Figure 1: Validator UI
The user interface is shown in Figure 1. From top to bottom, the main components are:
- Menus providing access to generic capabilities. The primary one is the "Processing"
menu. This allows the user to select the types of validation checks to be performed and the
level of logging output desired.
- The Tool Bar, which is used for:
- selection of one or more files to be validated, and
- access to the integrated Manifest Editor.
- The Logging panel used to display and filter the messages resulting from the validation
process
2) Using the Validator
2.1) Selecting Processing Options
- The first step is to configure basic options and preferences (e.g., logging output).
This is done via the check boxes in the Processing menu (Fig 2). The user may:
- filter validation-related messages based on their severity and
- enable or disable informational and status messages.
Figure 2: Logging Menu
- The next step is to select which files will be validated. There are three mechanisms
provided:
- Use the Open File... menu item to select an Avails file in either XML or
Excel format:
- The Recent.. menu item may be used to select from a history of recently
accessed files.
- A left-click on the 'File' text area (to the right of the button)
will pop open a File Chooser dialog.
If a directory is selected, all Avails files found in the directory will be processed.
Alternatively a single file may be selected. Note, however, that if the selected source is
a directory containing multiple Avails files, then all files will be validated against the
same set of options.
2.2) Running the Validator and Interpreting Output
Once all validation options have been set, the validation process may be executed via the
RUN
button.
- If the selected Avails is an XLSX file, the user will be prompted to select
from a list the template version the file is based on (e.g. "Avails v1.7.1"). If the XLSX
version is unknown (i.e., "UNK") the software will attempt to identify the version. If,
however, it incorrectly identifies the template version, further processing may return
invalid results.
- If the Avails is an XML file, processing proceeds without the need for this additional
input.
When the validation process completes, the results will be displayed in the Logging panel
(see Figure 3).
Figure 3: Validation Results
The navigation pane on the left side allows the user to select a sub-set of messages to be
displayed on the right side. Messages are hierarchically grouped first by the Avails file they
apply to, then by the severity level, and finally by the type of validation check resulting in the
message (e.g., CMD). The levels, in order of decreasing severity, are:
-
Fatal
: Indicates the inability to perform any processing on a file. For example, attempting to
process an Avails based on an unsupported version of the schema would result in a FATAL log
entry.
-
Error
: a problem that must be corrected. An example would be the absence of a required property or
the use of an unrecognized value for an enumerated type (e.g., an invalid language code)
-
Warning
: a problem or inconsistency that does not have to be corrected but may be worth looking
into. For example, a Transaction with more than one SuppressionLiftDate terms is
contradictory but may still be processable by a retailer.
-
Notice
: indicates that a recommended Best practice was not followed (e.g. the use of
non-EIDR ID values for IDs)
-
Debug
: diagnostic output that should only be produced when requested by Movie Labs.
The last type of log entry is an
Info
message. These are used to provide a user with summary and status information about the file
being validated. The generation of Info messages may be enabled or disabled via the
Processing -> Logging
menu (see Fig 2 above).
Icons are used to indicate the most severe problem found in any branch of the message
hierarchy. For example, Figure 3b shows that only one of the two files that were processed
contains errors.
Figure 3b: Severity of Log Messages
The message display pane on the right provides a table showing all the messages in which
ever branch of the message hierarchy has been selected in the navigation pane. Some log messages
will provide additional information via tool tips. Where possible, this will include
references to specific sections of the documentation that cover the identified problem.
The interpretation of the
Line
entry will depend on the type of Avails file being processed. For XML files it will be the line
number in the file while for XLSX files it is actually the row number in the sheet being
processed.
The displayed log messages may be sorted by means of a left-click on any of the column
headers. Subsequent left-clicks will reverse the sort order.
By right-clicking on the message display pane, a pop-up menu may be accessed (see Figure
4). Available actions are:
- show the XML associated with the error in an Editor window [for XML-formatted Avails
files only],
- clear the entire contents of the message log, or
- save to a file the currently displayed group of messages in CSV format
Figure 4: Message Log Pop-up Menu
The saving and/or clearing of the log file are simple operations and the user interface for
both of these is self-explanatory. Usage of the Editor is covered in detail in the next section.
2.3) Editing [XML files only]
2.3.1) Overview
The Avails Validator includes a built-in XML Editor that may be used to correct any errors found
during the validation process. Note that this is not intended to provide a full-featured XML
authoring capability similar to those provided by tools such as XML Spy or Oxygen-XML. Rather it is
focused on providing an easy-to-use and integrated capability for quickly correcting errors and
then re-running the validation tests.
The Editor UI is implemented as a separate window (see Figure 5). Multiple Editor windows
may be opened at the same time, with each displaying a different XML file. Note, however, that
there may only be one Editor window for any given file.
Figure 5: XML Editor
2.3.2) Launching the Editor
There are three ways to launch the XML Editor:
- As described in Section 2..2, an Editor may be launched by the context menu displayed
when the user right-clicks on a log entry.
The editor will scroll the display to the line associated
with the log entry.
- An Editor may be launched by right-clicking on the file name displayed in the navigation
pane: .
- An Editor may also be launched using the EDIT button in the tool bar:
When an editor is launched for a specific Avails file:
- if an editor window for the file has not been previously accessed, a new Editor will
be created and displayed.
- if an editor for the file already exists but has been minimized (i.e., iconified) by
the user, it will be opened and brought to the foreground.
- if an editor for the file already exists, it will scroll to display the selected
line in that file.
- if the log message used to access the editor does not have a specific location
associated with it, or the editor was launched using the Menu Bar, the current line will
be set to the first line in the file.
2.3.3) User Interface
The Editor window has the following components:
- a text pane which uses colors for syntax highlighting,
- a menu bar providing access to the available editing functions
- line numbers displayed on the left edge that includes markers indicating errors and
warnings, and
- display of status messages across the bottom of the editor window.
These are shown in Figure 6.
Figure 6: Editor UI
The status messages are linked to the marker icons displayed along side the line numbers. A
single left or right click on a marker will result in the associated log entry being displayed
in the status panel.
2.3.4) Saving Changes and Re-Validating
To save changes, simply use either the pull down menu or the
<Ctrl>S
shortcut. Once the Avails file has been saved the XML may be re-validated.
The changed Avails may also be saved under a new name using the
Save As
menu option. If the Avails is saved under a new name then the user must explicitly identify the
new Avails file as the Validator's
Source
before it can be validated. Also it is important to remember that the existing Editor
window will still be displaying the original Avails file. In order to edit the newly saved file,
the user must:
- select the new file as the source file to validate,
- run the validation, and then
- select one of the resulting log messages to open an Editor window for the new XML
file.
3) Format Conversion
3.1) Overview
The Avails Validator provides a translation capability that may be used to convert an
Avails file from one format to another. The current version of the software supports the
conversions:
- from XML to XLSX (e.g., from XML v2.2 to XLSX v1.7.3),
- from XLSX to XML (e.g., from v1.7.2 to XML v2.3),
- from one XLSX version to another (e.g. v1.7.2 to v1.7.3), or
- from one XML version to another (e.g. v2.2 to v2.3).
Regardless of the specific conversion being performed, the following guidelines apply:
- An Avails file must be valid before it can be translated. The Validator UI
will disable the Translate option for any file that contains validation errors or
has yet to be validated.
- Any Avails file generated by the Translation function should be validated
before using. Translation is a best effort capability. Due to inconsistencies when
translating between different formats (e.g. XML to XLSX) or different versions of the same
format (e.g., XLSX 1.7.1 to XLSX 1.7.3) the translated Avails may not be valid even though
the original Avails file was.
The following sections provide general guidance for conversion. Detailed guidance for specific
conversions is provided in the
Avails Version Mapping
document.
3.2) Converting XML to Excel
The Avails XML schema supports all of the capabilities and constructs defined by the EMA Avails
Metadata standards. In contrast, the semantics supported by the Excel version of an Avails are
very limited. As a result, information present in an XML file may not be supportable in an Excel
file. Not all XML Avails will, therefore, be supportable as an Excel file. Refer to the
Avails Version Mapping
document for specific limitations and assumptions associated with each conversion.
Conversion to v1.7.3 or older
Prior to v1.8, the Excel format required that
the Avails to be organized by
Asset/WorkType
in that the contents of a spreadsheet will consist entirely of Movie-related or TV-related
Avails. When converting XML to a pre-v1.8 format, the conversion process will, therefore,
generate for each XML document a single Excel
workbook containing exactly two spreadsheet: one for movies and one for TV. Note, however, that
the Excel standard for Avails requires a workbook to contain a single sheet. The user is responsible for splitting the generated Excel
file into two separate workbooks with one spreadsheet each.
3.3) Converting Excel to XML
The Avails Validator can translate a valid Excel Avails file into an XML Avails. The process is
fairly simple as the XML format will support any Avails structure that can be specified via
Excel. The sole issue is that an XML Avail requires a
ShortDescription
which is absent from the Excel version. The translator will therefore create a description that
indicates the XLSX file and worksheet that the XML was generated along with a timestamp. The
full syntax is:
generated XML from {file-name}:Sheet_n on yyyy.mm.dd.hh.mm.ss
3.4) User Interface
To translate a file:
First validate the file using the normal mechanisms. Correct any errors
identified.
Open the pop-up menu via a right-click on the file name displayed in the
navigation pane:
Figure 7: File Context Pop-up Menu
If all validation errors have been corrected, the 'Translate' action will be
enabled.
Selecting '
Translate
' will result in the display of the Avails Translation Dialog:
Figure 8: Avails Translation Dialog
The checkboxes should be used to select one or more output formats. A checkbox will be
disabled if the software does not support conversion from the input format to that
particular output format.
Output files will saved to the indicated folder. The name of Excel file will be used as
the base name for the XML but the user has the option of changing this if desired. There
is also the option of appending a version suffix to the output file's name. For
example, the settings shown in Fig 8 will produce two output files:
- EMA_Avails-TV_v1-7.3_v2.2.xml, and
- EMA_Avails-TV_v1-7.3_v2.3.xml
The translator will log any changes it makes to the Avail specifications as a result of
limitations in the conversion process (see Sections 3.2 and 3.3). Figure 9 shows an
example output:
Figure 9: Avails Translation Log Report
4) Running Scripts
4.1) Functionality
Validation of multiple Avails files may be performed using scripts that can specify any of
same options and settings available thru the user interface. A script may easily be used to
process a set of manifests with specified sub-sets being handled using different options. All
results are automatically displayed in the GUI's log display but the script engine supports the
option of also writing the log to a file.
4.2) Writing Command Scripts
4.2.1) Structure
A script file is written using the JSON
syntax. The structure for a validation script is as follows:
- Command: should be specified as validate . The validation command has OPTIONAL
sub-elements followed by a list of files to process.
4.2.2) Examples
The following is an example of script that validates two files plus any additional Avails
found in a specific folder and then saves the message log in a single output file:
{
"validate":{
"pathPrefix":"./AvailsDemos/",
"logging":{
"level":"Warning",
"output":"./scriptLog01.xml"
},
"avails":[
{
"file":"si_tests/CMM_BBB_v0.1.xml"
},
{
"file":"si_tests/CMM_Sita_v0.1.xml"
},
{
"file":"studioFoo"
}
]
}
}
The next two examples illustrate the use, or non-use, of the
pathPrefix
. In the first example, all relative paths are resolved using the present working directory as
the base. Both
foo1.xml
and
foo2.xml
should therefore be in the
pwd
.
{
"validate":{
"avails":[
{
"file":"foo1.xml"
},
{
"file":"./foo2.xml"
},
{
"file":"/foo3.xml"
}
]
}
}
In the next example,
foo1.xml
and
foo2.xml
are still co-located but are now in in a sub-directory of the directory containing the script
file.
foo3.xml
should still be in the same location as the previous examples since it is specified using an
absolute path.
{
"validate":{
"pathPrefix":"./AvailsDemos/",
"avails":[
{
"file":"foo1.xml"
},
{
"file":"./foo2.xml"
},
{
"file":"/foo3.xml"
}
]
}
}
4.3) User Interface
Selection and execution of a script is via the
Run Script..
menu entry. Script files are not selectable using the
File
text-entry field used to specify an Avails XML file.
Once a script file has been selected the execution is automatic. It is recommended that the
contents of the log display be cleared prior to executing a script. Failure to do so will result
in any previous messages being included in the saved log file.

British champ Tanfield joins French cycling oufit AG2R
Vaujany - British cycling champion Harry Tanfield has signed on with AG2R La Mondiale for next season, the French team said Tuesday.
The 24-year-old who won the individual pursuit at the British track championships last year will line up with Romain Bardet, top climber in the 2019 Tour de France, in a team that has brought in four newcomers ahead of the 2020 season.
Team director Vincent Lavenu said he came close to signing the Briton a year ago.
"He is a talented rider who is going to help us in the time trials," Lavenu said. "He will bring quality to the classics races."


PraxisCORE is a modular JVM runtime for cyberphysical programming, supporting real-time coding of real-time systems. It is the heart of PraxisLIVE. With a distributed forest-of-actors architecture, runtime code changes and comprehensive introspection, PraxisCORE brings aspects of Erlang, Smalltalk and Extempore into the Java world ... a powerful platform for media processing, data visualisation, sensors, robotics, IoT, and lots more!
PraxisCORE is based on the actor model, adapted to the needs of real-time media and data processing. Components (actors) exist in an unlimited number of trees, communicating via asynchronous lock-free messages. In addition, PraxisCORE supports lightweight synchronous dataflow between siblings for real-time data processing. Each tree root handles message dispatch and scheduling.
PraxisCORE is designed from the ground up to support runtime code changes. Asynchronous code compilation and introspection, with carefully designed state retention, allows for behaviour to be swapped atomically into a running system without pauses or "glitches". PraxisCORE treats code as data, allowing for powerful real-time meta-programming capabilities.
Trees can be easily distributed across multiple processes or a network without code changes. Service discovery and resource loading are integrated into the runtime. Timing sensitive tasks can be run in separate VM's with optimum memory configuration. Projects on small devices (like the Pi) can be developed remotely or run in a cluster.
PraxisCORE is highly modular - use just the core actor system, or bring in as many modules from the standard PraxisLIVE distribution as you need. Available pre-existing modules include support for audio and video processing, live data visualisation, working with TinkerForge sensors and electronics, and controlling projects via custom GUIs, MIDI and OSC.
Individual components can be easily exported in plain text, shared and reused across projects. A growing library of pre-built custom components is available to use, alongside those which ship with the runtime.
While PraxisCORE is a Java API, the recommended way to build projects is inside PraxisLIVE. Built on top of the Apache NetBeans IDE, the PraxisLIVE IDE inherits world-class code editing functionality. On top of that it provides live visualisation and editing of actor graphs; and live introspection and editing of properties.

The FastCGI application, s, did not terminate the headers properly. A total of d bytes were recieved.
Headers are terminated by an empty line, e.g.
printf("Content-type: text/html\r\nStatus: 200 OK\r\n\r\n");
See the CGI specification for more information.
Windows first searches the set of pre-installed DLLs such as the performance library (KERNEL32.DLL) and the security library (USER32.DLL). It then searches for the DLLs in the following sequence:
Note that the LIBPATH environment variable is not used.
mod_fastcgi, by default, clears the environment of FastCGI applications it starts (with the exception of SystemRoot). To pass or set an environment variable to a FastCGI application use the -initial-env argument to FastCgiConfig or FastCgiServer.
When a request handle object is destroyed that has accepted a connection without finishing it, the connection will automatically be finished. Usually, this is what you want, although it is preferable to explicitly call the Finish() method.
When you fork, however, without calling exec as well, i.e. when you have two instance of perl running, the request handle object will (eventually) be destroyed in both instances of perl. As a result, a possible request being handled will be finished when the object is destroyed for the first time. This is probably not what you expect, since you will usually only be handling the request in either the parent or the child. To inhibit this unwanted request finishing, you can send the Detach() message to the request handle object. In a detached state, destruction will not lead to any finishing of requests. It is advised you call Detach() before forking and Attach afterwards (in the process that will continue handling the request).
Before doing this though, please think about whether or not you really need to fork inside the accept loop. Since the FastCGI paradigm is different from the normal CGI one, you'll find that there are situations where you would fork in a CGI context, whereas it may not be necessary in a FastCGI context. In other cases, you're better off doing the forking before the accept loop.
Conversely, when you call exec without forking, the object will not be destroyed and no connection will automatically be finished, so in that case you are forced to do it yourself.
#!/usr/bin/perl use strict; use warnings; use FCGI; my $request = FCGI::Request(); while ($request->Accept() >= 0) { # do stuff with $request $request->Detach(); my $child; $child = fork; if (!defined $child) { # error handling } elsif ($child == 0) { # do child stuff } $request->Attach(); # continue processing request $request->Finish(); }
All FastCGI applications should handle PIPE and TERM , mod_fastcgi spawned applications should also handle USR1.
PIPE occurs when trying to write/print to a file descriptor that has been closed. Under mod_fastcgi, if a client aborts a connection before it completes mod_fastcgi does too. At a minimum, SIGPIPE should be ignored (this is already setup in applications spawned by mod_fastcgi). Ideally, it should result in an early abort of the request handling within your application and a return to the top of the FastCGI accept() loop.
USR1 may be received by FastCGI applications spawned by mod_fastcgi. Apache uses this signal to request a "graceful" process shutdown (e.g. its used by "apachectl restart"). When mod_fastcgi's Process Manager receives USR1 it sends TERM to all of the FastCGI applications it spawned and then exits (its gets restarted by Apache). This means that, under Apache/mod_fastcgi, a FastCGI application that receives USR1 from Apache will also receive TERM from the process manager. FastCGI applications expected to be run under the control of mod_fastcgi/Apache should handle USR1 by finishing any request in process and then shutting down.
TERM is the standard signal sent to applications to request shutdown. Typically, this is considered a request for "clean" shutdown, i.e. finish anything your in the middle of (within reason), free resources such as database connections, and exit. When Apache receives TERM, it does not finish handling requests in progress. Whether or not you finish any request in process when TERM is received is your decision, but keep in mind that under mod_fastcgi/Apache the TERM may be a "graceful" request in disguise. I always finish any request in process before exiting.
Handling signals can be tricky. Consult the documentation for your language and system for restrictions and idiosyncrasies. In general, its always best to do as little as possible from within a signal handler.

The Basics of Creating Rails Plugins
A Rails plugin is either an extension or a modification of the core framework. Plugins provide:
-
a way for developers to share bleeding-edge ideas without hurting the stable code base
-
a segmented architecture so that units of code can be fixed or updated on their own release schedule
-
an outlet for the core developers so that they don’t have to include every cool new feature under the sun
After reading this guide you should be familiar with:
-
Creating a plugin from scratch
-
Writing and running tests for the plugin
-
Storing models, views, controllers, helpers and even other plugins in your plugins
-
Writing generators
-
Writing custom Rake tasks in your plugin
-
Generating RDoc documentation for your plugin
-
Avoiding common pitfalls with init.rb
This guide describes how to build a test-driven plugin that will:
-
Extend core ruby classes like Hash and String
-
Add methods to ActiveRecord::Base in the tradition of the acts_as plugins
-
Add a view helper that can be used in erb templates
-
Add a new generator that will generate a migration
-
Add a custom generator command
-
A custom route method that can be used in routes.rb
For the purpose of this guide pretend for a moment that you are an avid bird watcher. Your favorite bird is the Yaffle, and you want to create a plugin that allows other developers to share in the Yaffle goodness. First, you need to get setup for development.
1. Setup
1.1. Create the basic app
The examples in this guide require that you have a working rails application. To create a simple rails app execute:
gem install rails rails yaffle_guide cd yaffle_guide script/generate scaffold bird name:string rake db:migrate script/server
Then navigate to http://localhost:3000/birds. Make sure you have a functioning rails app before continuing.
|
Editor's note: The aforementioned instructions will work for sqlite3. For more detailed instructions on how to create a rails app for other databases see the API docs. |
1.2. Generate the plugin skeleton
Rails ships with a plugin generator which creates a basic plugin skeleton. Pass the plugin name, either CamelCased or under_scored, as an argument. Pass --with-generator to add an example generator also.
This creates a plugin in vendor/plugins including an init.rb and README as well as standard lib, task, and test directories.
Examples:
./script/generate plugin yaffle ./script/generate plugin yaffle --with-generator
To get more detailed help on the plugin generator, type ./script/generate plugin.
Later on this guide will describe how to work with generators, so go ahead and generate your plugin with the --with-generator option now:
./script/generate plugin yaffle --with-generator
You should see the following output:
create vendor/plugins/yaffle/lib create vendor/plugins/yaffle/tasks create vendor/plugins/yaffle/test create vendor/plugins/yaffle/README create vendor/plugins/yaffle/MIT-LICENSE create vendor/plugins/yaffle/Rakefile create vendor/plugins/yaffle/init.rb create vendor/plugins/yaffle/install.rb create vendor/plugins/yaffle/uninstall.rb create vendor/plugins/yaffle/lib/yaffle.rb create vendor/plugins/yaffle/tasks/yaffle_tasks.rake create vendor/plugins/yaffle/test/core_ext_test.rb create vendor/plugins/yaffle/generators create vendor/plugins/yaffle/generators/yaffle create vendor/plugins/yaffle/generators/yaffle/templates create vendor/plugins/yaffle/generators/yaffle/yaffle_generator.rb create vendor/plugins/yaffle/generators/yaffle/USAGE
1.3. Organize your files
To make it easy to organize your files and to make the plugin more compatible with GemPlugins, start out by altering your file system to look like this:
|-- lib | |-- yaffle | `-- yaffle.rb `-- rails | `-- init.rb
vendor/plugins/yaffle/rails/init.rb
require 'yaffle'
Now you can add any require statements to lib/yaffle.rb and keep init.rb clean.
2. Tests
In this guide you will learn how to test your plugin against multiple different database adapters using Active Record. To setup your plugin to allow for easy testing you'll need to add 3 files:
-
A database.yml file with all of your connection strings
-
A schema.rb file with your table definitions
-
A test helper method that sets up the database
2.1. Test Setup
vendor/plugins/yaffle/test/database.yml:
sqlite: :adapter: sqlite :dbfile: vendor/plugins/yaffle/test/yaffle_plugin.sqlite.db sqlite3: :adapter: sqlite3 :dbfile: vendor/plugins/yaffle/test/yaffle_plugin.sqlite3.db postgresql: :adapter: postgresql :username: postgres :password: postgres :database: yaffle_plugin_test :min_messages: ERROR mysql: :adapter: mysql :host: localhost :username: root :password: password :database: yaffle_plugin_test
For this guide you'll need 2 tables/models, Hickwalls and Wickwalls, so add the following:
vendor/plugins/yaffle/test/schema.rb:
ActiveRecord::Schema.define(:version => 0) do create_table :hickwalls, :force => true do |t| t.string :name t.string :last_squawk t.datetime :last_squawked_at end create_table :wickwalls, :force => true do |t| t.string :name t.string :last_tweet t.datetime :last_tweeted_at end create_table :woodpeckers, :force => true do |t| t.string :name end end
vendor/plugins/yaffle/test/test_helper.rb:
ENV['RAILS_ENV'] = 'test' ENV['RAILS_ROOT'] ||= File.dirname(__FILE__) + '/../../../..' require 'test/unit' require File.expand_path(File.join(ENV['RAILS_ROOT'], 'config/environment.rb')) def load_schema config = YAML::load(IO.read(File.dirname(__FILE__) + '/database.yml')) ActiveRecord::Base.logger = Logger.new(File.dirname(__FILE__) + "/debug.log") db_adapter = ENV['DB'] # no db passed, try one of these fine config-free DBs before bombing. db_adapter ||= begin require 'rubygems' require 'sqlite' 'sqlite' rescue MissingSourceFile begin require 'sqlite3' 'sqlite3' rescue MissingSourceFile end end if db_adapter.nil? raise "No DB Adapter selected. Pass the DB= option to pick one, or install Sqlite or Sqlite3." end ActiveRecord::Base.establish_connection(config[db_adapter]) load(File.dirname(__FILE__) + "/schema.rb") require File.dirname(__FILE__) + '/../rails/init.rb' end
Now whenever you write a test that requires the database, you can call load_schema.
2.2. Run the plugin tests
Once you have these files in place, you can write your first test to ensure that your plugin-testing setup is correct. By default rails generates a file in vendor/plugins/yaffle/test/yaffle_test.rb with a sample test. Replace the contents of that file with:
vendor/plugins/yaffle/test/yaffle_test.rb:
require File.dirname(__FILE__) + '/test_helper.rb' class YaffleTest < Test::Unit::TestCase load_schema class Hickwall < ActiveRecord::Base end class Wickwall < ActiveRecord::Base end def test_schema_has_loaded_correctly assert_equal [], Hickwall.all assert_equal [], Wickwall.all end end
To run this, go to the plugin directory and run rake:
cd vendor/plugins/yaffle rake
You should see output like:
/opt/local/bin/ruby -Ilib:lib "/opt/local/lib/ruby/gems/1.8/gems/rake-0.8.3/lib/rake/rake_test_loader.rb" "test/yaffle_test.rb" -- create_table(:hickwalls, {:force=>true}) -> 0.0220s -- create_table(:wickwalls, {:force=>true}) -> 0.0077s -- initialize_schema_migrations_table() -> 0.0007s -- assume_migrated_upto_version(0) -> 0.0007s Loaded suite /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.3/lib/rake/rake_test_loader Started . Finished in 0.002236 seconds. 1 test, 1 assertion, 0 failures, 0 errors
By default the setup above runs your tests with sqlite or sqlite3. To run tests with one of the other connection strings specified in database.yml, pass the DB environment variable to rake:
rake DB=sqlite rake DB=sqlite3 rake DB=mysql rake DB=postgresql
Now you are ready to test-drive your plugin!
3. Extending core classes
This section will explain how to add a method to String that will be available anywhere in your rails app.
In this example you will add a method to String named to_squawk. To begin, create a new test file with a few assertions:
vendor/plugins/yaffle/test/core_ext_test.rb
require File.dirname(__FILE__) + '/test_helper.rb' class CoreExtTest < Test::Unit::TestCase def test_to_squawk_prepends_the_word_squawk assert_equal "squawk! Hello World", "Hello World".to_squawk end end
Navigate to your plugin directory and run rake test:
cd vendor/plugins/yaffle rake test
The test above should fail with the message:
1) Error: test_to_squawk_prepends_the_word_squawk(CoreExtTest): NoMethodError: undefined method `to_squawk' for "Hello World":String ./test/core_ext_test.rb:5:in `test_to_squawk_prepends_the_word_squawk'
Great - now you are ready to start development.
Then in lib/yaffle.rb require lib/core_ext.rb:
vendor/plugins/yaffle/lib/yaffle.rb
require "yaffle/core_ext"
Finally, create the core_ext.rb file and add the to_squawk method:
vendor/plugins/yaffle/lib/yaffle/core_ext.rb
String.class_eval do def to_squawk "squawk! #{self}".strip end end
To test that your method does what it says it does, run the unit tests with rake from your plugin directory. To see this in action, fire up a console and start squawking:
$ ./script/console >> "Hello World".to_squawk => "squawk! Hello World"
3.1. Working with init.rb
When rails loads plugins it looks for the file named init.rb or rails/init.rb. However, when the plugin is initialized, init.rb is invoked via eval (not require) so it has slightly different behavior.
Under certain circumstances if you reopen classes or modules in init.rb you may inadvertently create a new class, rather than reopening an existing class. A better alternative is to reopen the class in a different file, and require that file from init.rb, as shown above.
If you must reopen a class in init.rb you can use module_eval or class_eval to avoid any issues:
vendor/plugins/yaffle/rails/init.rb
Hash.class_eval do def is_a_special_hash? true end end
Another way is to explicitly define the top-level module space for all modules and classes, like ::Hash:
vendor/plugins/yaffle/rails/init.rb
class ::Hash def is_a_special_hash? true end end
4. Add an acts_as method to Active Record
A common pattern in plugins is to add a method called acts_as_something to models. In this case, you want to write a method called acts_as_yaffle that adds a squawk method to your models.
To begin, set up your files so that you have:
vendor/plugins/yaffle/test/acts_as_yaffle_test.rb
require File.dirname(__FILE__) + '/test_helper.rb' class ActsAsYaffleTest < Test::Unit::TestCase end
vendor/plugins/yaffle/lib/yaffle.rb
require 'yaffle/acts_as_yaffle'
vendor/plugins/yaffle/lib/yaffle/acts_as_yaffle.rb
module Yaffle # your code will go here end
Note that after requiring acts_as_yaffle you also have to include it into ActiveRecord::Base so that your plugin methods will be available to the rails models.
One of the most common plugin patterns for acts_as_yaffle plugins is to structure your file like so:
vendor/plugins/yaffle/lib/yaffle/acts_as_yaffle.rb
module Yaffle def self.included(base) base.send :extend, ClassMethods end module ClassMethods # any method placed here will apply to classes, like Hickwall def acts_as_something send :include, InstanceMethods end end module InstanceMethods # any method placed here will apply to instaces, like @hickwall end end
With structure you can easily separate the methods that will be used for the class (like Hickwall.some_method) and the instance (like @hickwell.some_method).
4.1. Add a class method
This plugin will expect that you've added a method to your model named last_squawk. However, the plugin users might have already defined a method on their model named last_squawk that they use for something else. This plugin will allow the name to be changed by adding a class method called yaffle_text_field.
To start out, write a failing test that shows the behavior you'd like:
vendor/plugins/yaffle/test/acts_as_yaffle_test.rb
require File.dirname(__FILE__) + '/test_helper.rb' class Hickwall < ActiveRecord::Base acts_as_yaffle end class Wickwall < ActiveRecord::Base acts_as_yaffle :yaffle_text_field => :last_tweet end class ActsAsYaffleTest < Test::Unit::TestCase load_schema def test_a_hickwalls_yaffle_text_field_should_be_last_squawk assert_equal "last_squawk", Hickwall.yaffle_text_field end def test_a_wickwalls_yaffle_text_field_should_be_last_tweet assert_equal "last_tweet", Wickwall.yaffle_text_field end end
To make these tests pass, you could modify your acts_as_yaffle file like so:
vendor/plugins/yaffle/lib/yaffle/acts_as_yaffle.rb
module Yaffle def self.included(base) base.send :extend, ClassMethods end module ClassMethods def acts_as_yaffle(options = {}) cattr_accessor :yaffle_text_field self.yaffle_text_field = (options[:yaffle_text_field] || :last_squawk).to_s end end end ActiveRecord::Base.send :include, Yaffle
4.2. Add an instance method
This plugin will add a method named squawk to any Active Record objects that call acts_as_yaffle. The squawk method will simply set the value of one of the fields in the database.
To start out, write a failing test that shows the behavior you'd like:
vendor/plugins/yaffle/test/acts_as_yaffle_test.rb
require File.dirname(__FILE__) + '/test_helper.rb' class Hickwall < ActiveRecord::Base acts_as_yaffle end class Wickwall < ActiveRecord::Base acts_as_yaffle :yaffle_text_field => :last_tweet end class ActsAsYaffleTest < Test::Unit::TestCase load_schema def test_a_hickwalls_yaffle_text_field_should_be_last_squawk assert_equal "last_squawk", Hickwall.yaffle_text_field end def test_a_wickwalls_yaffle_text_field_should_be_last_tweet assert_equal "last_tweet", Wickwall.yaffle_text_field end def test_hickwalls_squawk_should_populate_last_squawk hickwall = Hickwall.new hickwall.squawk("Hello World") assert_equal "squawk! Hello World", hickwall.last_squawk end def test_wickwalls_squawk_should_populate_last_tweeted_at wickwall = Wickwall.new wickwall.squawk("Hello World") assert_equal "squawk! Hello World", wickwall.last_tweet end end
Run this test to make sure the last two tests fail, then update acts_as_yaffle.rb to look like this:
vendor/plugins/yaffle/lib/yaffle/acts_as_yaffle.rb
module Yaffle def self.included(base) base.send :extend, ClassMethods end module ClassMethods def acts_as_yaffle(options = {}) cattr_accessor :yaffle_text_field self.yaffle_text_field = (options[:yaffle_text_field] || :last_squawk).to_s send :include, InstanceMethods end end module InstanceMethods def squawk(string) write_attribute(self.class.yaffle_text_field, string.to_squawk) end end end ActiveRecord::Base.send :include, Yaffle
|
Editor's note: The use of write_attribute to write to the field in model is just one example of how a plugin can interact with the model, and will not always be the right method to use. For example, you could also use send("#{self.class.yaffle_text_field}=", string.to_squawk). |
5. Models
This section describes how to add a model named Woodpecker to your plugin that will behave the same as a model in your main app. When storing models, controllers, views and helpers in your plugin, it's customary to keep them in directories that match the rails directories. For this example, create a file structure like this:
vendor/plugins/yaffle/ |-- lib | |-- app | | |-- controllers | | |-- helpers | | |-- models | | | `-- woodpecker.rb | | `-- views | |-- yaffle | | |-- acts_as_yaffle.rb | | |-- commands.rb | | `-- core_ext.rb | `-- yaffle.rb
As always, start with a test:
vendor/plugins/yaffle/yaffle/woodpecker_test.rb:
require File.dirname(__FILE__) + '/test_helper.rb' class WoodpeckerTest < Test::Unit::TestCase load_schema def test_woodpecker assert_kind_of Woodpecker, Woodpecker.new end end
This is just a simple test to make sure the class is being loaded correctly. After watching it fail with rake, you can make it pass like so:
vendor/plugins/yaffle/lib/yaffle.rb:
%w{ models }.each do |dir| path = File.join(File.dirname(__FILE__), 'app', dir) $LOAD_PATH << path ActiveSupport::Dependencies.load_paths << path ActiveSupport::Dependencies.load_once_paths.delete(path) end
Adding directories to the load path makes them appear just like files in the the main app directory - except that they are only loaded once, so you have to restart the web server to see the changes in the browser. Removing directories from the load_once_paths allow those changes to picked up as soon as you save the file - without having to restart the web server. This is particularly useful as you develop the plugin.
vendor/plugins/yaffle/lib/app/models/woodpecker.rb:
class Woodpecker < ActiveRecord::Base end
Finally, add the following to your plugin's schema.rb:
vendor/plugins/yaffle/test/schema.rb:
create_table :woodpeckers, :force => true do |t| t.string :name end
Now your test should be passing, and you should be able to use the Woodpecker model from within your rails app, and any changes made to it are reflected immediately when running in development mode.
6. Controllers
This section describes how to add a controller named woodpeckers to your plugin that will behave the same as a controller in your main app. This is very similar to adding a model.
You can test your plugin's controller as you would test any other controller:
vendor/plugins/yaffle/test/woodpeckers_controller_test.rb:
require File.dirname(__FILE__) + '/test_helper.rb' require 'woodpeckers_controller' require 'action_controller/test_process' class WoodpeckersController; def rescue_action(e) raise e end; end class WoodpeckersControllerTest < Test::Unit::TestCase def setup @controller = WoodpeckersController.new @request = ActionController::TestRequest.new @response = ActionController::TestResponse.new ActionController::Routing::Routes.draw do |map| map.resources :woodpeckers end end def test_index get :index assert_response :success end end
This is just a simple test to make sure the controller is being loaded correctly. After watching it fail with rake, you can make it pass like so:
vendor/plugins/yaffle/lib/yaffle.rb:
%w{ models controllers }.each do |dir| path = File.join(File.dirname(__FILE__), 'app', dir) $LOAD_PATH << path ActiveSupport::Dependencies.load_paths << path ActiveSupport::Dependencies.load_once_paths.delete(path) end
vendor/plugins/yaffle/lib/app/controllers/woodpeckers_controller.rb:
class WoodpeckersController < ActionController::Base def index render :text => "Squawk!" end end
Now your test should be passing, and you should be able to use the Woodpeckers controller in your app. If you add a route for the woodpeckers controller you can start up your server and go to http://localhost:3000/woodpeckers to see your controller in action.
7. Helpers
This section describes how to add a helper named WoodpeckersHelper to your plugin that will behave the same as a helper in your main app. This is very similar to adding a model and a controller.
You can test your plugin's helper as you would test any other helper:
vendor/plugins/yaffle/test/woodpeckers_helper_test.rb
require File.dirname(__FILE__) + '/test_helper.rb' include WoodpeckersHelper class WoodpeckersHelperTest < Test::Unit::TestCase def test_tweet assert_equal "Tweet! Hello", tweet("Hello") end end
This is just a simple test to make sure the helper is being loaded correctly. After watching it fail with rake, you can make it pass like so:
vendor/plugins/yaffle/lib/yaffle.rb:
%w{ models controllers helpers }.each do |dir| path = File.join(File.dirname(__FILE__), 'app', dir) $LOAD_PATH << path ActiveSupport::Dependencies.load_paths << path ActiveSupport::Dependencies.load_once_paths.delete(path) end
vendor/plugins/yaffle/lib/app/helpers/woodpeckers_helper.rb:
module WoodpeckersHelper def tweet(text) "Tweet! #{text}" end end
Now your test should be passing, and you should be able to use the Woodpeckers helper in your app.
8. Routes
In a standard routes.rb file you use routes like map.connect or map.resources. You can add your own custom routes from a plugin. This section will describe how to add a custom method called that can be called with map.yaffles.
Testing routes from plugins is slightly different from testing routes in a standard rails app. To begin, add a test like this:
vendor/plugins/yaffle/test/routing_test.rb
require "#{File.dirname(__FILE__)}/test_helper" class RoutingTest < Test::Unit::TestCase def setup ActionController::Routing::Routes.draw do |map| map.yaffles end end def test_yaffles_route assert_recognition :get, "/yaffles", :controller => "yaffles_controller", :action => "index" end private def assert_recognition(method, path, options) result = ActionController::Routing::Routes.recognize_path(path, :method => method) assert_equal options, result end end
Once you see the tests fail by running rake, you can make them pass with:
vendor/plugins/yaffle/lib/yaffle.rb
require "yaffle/routing"
vendor/plugins/yaffle/lib/yaffle/routing.rb
module Yaffle #:nodoc: module Routing #:nodoc: module MapperExtensions def yaffles @set.add_route("/yaffles", {:controller => "yaffles_controller", :action => "index"}) end end end end ActionController::Routing::RouteSet::Mapper.send :include, Yaffle::Routing::MapperExtensions
config/routes.rb
ActionController::Routing::Routes.draw do |map| map.yaffles end
You can also see if your routes work by running rake routes from your app directory.
9. Generators
Many plugins ship with generators. When you created the plugin above, you specified the —with-generator option, so you already have the generator stubs in vendor/plugins/yaffle/generators/yaffle.
Building generators is a complex topic unto itself and this section will cover one small aspect of generators: generating a simple text file.
9.1. Testing generators
Many rails plugin authors do not test their generators, however testing generators is quite simple. A typical generator test does the following:
-
Creates a new fake rails root directory that will serve as destination
-
Runs the generator
-
Asserts that the correct files were generated
-
Removes the fake rails root
This section will describe how to create a simple generator that adds a file. For the generator in this section, the test could look something like this:
vendor/plugins/yaffle/test/definition_generator_test.rb
require File.dirname(__FILE__) + '/test_helper.rb' require 'rails_generator' require 'rails_generator/scripts/generate' class DefinitionGeneratorTest < Test::Unit::TestCase def setup FileUtils.mkdir_p(fake_rails_root) @original_files = file_list end def teardown FileUtils.rm_r(fake_rails_root) end def test_generates_correct_file_name Rails::Generator::Scripts::Generate.new.run(["yaffle_definition"], :destination => fake_rails_root) new_file = (file_list - @original_files).first assert_equal "definition.txt", File.basename(new_file) end private def fake_rails_root File.join(File.dirname(__FILE__), 'rails_root') end def file_list Dir.glob(File.join(fake_rails_root, "*")) end end
You can run rake from the plugin directory to see this fail. Unless you are doing more advanced generator commands it typically suffices to just test the Generate script, and trust that rails will handle the Destroy and Update commands for you.
To make it pass, create the generator:
vendor/plugins/yaffle/generators/yaffle_definition/yaffle_definition_generator.rb
class YaffleDefinitionGenerator < Rails::Generator::Base def manifest record do |m| m.file "definition.txt", "definition.txt" end end end
9.2. The USAGE file
If you plan to distribute your plugin, developers will expect at least a minimum of documentation. You can add simple documentation to the generator by updating the USAGE file.
Rails ships with several built-in generators. You can see all of the generators available to you by typing the following at the command line:
./script/generate
You should see something like this:
Installed Generators Plugins (vendor/plugins): yaffle_definition Builtin: controller, integration_test, mailer, migration, model, observer, plugin, resource, scaffold, session_migration
When you run script/generate yaffle_definition -h you should see the contents of your vendor/plugins/yaffle/generators/yaffle_definition/USAGE.
For this plugin, update the USAGE file could look like this:
Description: Adds a file with the definition of a Yaffle to the app's main directory
10. Generator Commands
You may have noticed above that you can used one of the built-in rails migration commands migration_template. If your plugin needs to add and remove lines of text from existing files you will need to write your own generator methods.
This section describes how you you can create your own commands to add and remove a line of text from config/routes.rb.
To start, add the following test method:
vendor/plugins/yaffle/test/route_generator_test.rb
require File.dirname(__FILE__) + '/test_helper.rb' require 'rails_generator' require 'rails_generator/scripts/generate' require 'rails_generator/scripts/destroy' class RouteGeneratorTest < Test::Unit::TestCase def setup FileUtils.mkdir_p(File.join(fake_rails_root, "config")) end def teardown FileUtils.rm_r(fake_rails_root) end def test_generates_route content = <<-END ActionController::Routing::Routes.draw do |map| map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format' end END File.open(routes_path, 'wb') {|f| f.write(content) } Rails::Generator::Scripts::Generate.new.run(["yaffle_route"], :destination => fake_rails_root) assert_match /map\.yaffles/, File.read(routes_path) end def test_destroys_route content = <<-END ActionController::Routing::Routes.draw do |map| map.yaffles map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format' end END File.open(routes_path, 'wb') {|f| f.write(content) } Rails::Generator::Scripts::Destroy.new.run(["yaffle_route"], :destination => fake_rails_root) assert_no_match /map\.yaffles/, File.read(routes_path) end private def fake_rails_root File.join(File.dirname(__FILE__), "rails_root") end def routes_path File.join(fake_rails_root, "config", "routes.rb") end end
Run rake to watch the test fail, then make the test pass add the following:
vendor/plugins/yaffle/lib/yaffle.rb
require "yaffle/commands"
vendor/plugins/yaffle/lib/yaffle/commands.rb
require 'rails_generator' require 'rails_generator/commands' module Yaffle #:nodoc: module Generator #:nodoc: module Commands #:nodoc: module Create def yaffle_route logger.route "map.yaffle" look_for = 'ActionController::Routing::Routes.draw do |map|' unless options[:pretend] gsub_file('config/routes.rb', /(#{Regexp.escape(look_for)})/mi){|match| "#{match}\n map.yaffles\n"} end end end module Destroy def yaffle_route logger.route "map.yaffle" gsub_file 'config/routes.rb', /\n.+?map\.yaffles/mi, '' end end module List def yaffle_route end end module Update def yaffle_route end end end end end Rails::Generator::Commands::Create.send :include, Yaffle::Generator::Commands::Create Rails::Generator::Commands::Destroy.send :include, Yaffle::Generator::Commands::Destroy Rails::Generator::Commands::List.send :include, Yaffle::Generator::Commands::List Rails::Generator::Commands::Update.send :include, Yaffle::Generator::Commands::Update
vendor/plugins/yaffle/generators/yaffle/yaffle_route_generator.rb
class YaffleRouteGenerator < Rails::Generator::Base def manifest record do |m| m.yaffle_route end end end
To see this work, type:
./script/generate yaffle_route ./script/destroy yaffle_route
|
Editor's note: If you haven't set up the custom route from above, script/destroy will fail and you'll have to remove it manually. |
11. Migrations
If your plugin requires changes to the app's database you will likely want to somehow add migrations. Rails does not include any built-in support for calling migrations from plugins, but you can still make it easy for developers to call migrations from plugins.
If you have a very simple needs, like creating a table that will always have the same name and columns, then you can use a more simple solution, like creating a custom rake task or method. If your migration needs user input to supply table names or other options, you probably want to opt for generating a migration.
Let's say you have the following migration in your plugin:
vendor/plugins/yaffle/lib/db/migrate/20081116181115_create_birdhouses.rb:
class CreateBirdhouses < ActiveRecord::Migration def self.up create_table :birdhouses, :force => true do |t| t.string :name t.timestamps end end def self.down drop_table :birdhouses end end
Here are a few possibilities for how to allow developers to use your plugin migrations:
11.1. Create a custom rake task
vendor/plugins/yaffle/lib/db/migrate/20081116181115_create_birdhouses.rb:
class CreateBirdhouses < ActiveRecord::Migration def self.up create_table :birdhouses, :force => true do |t| t.string :name t.timestamps end end def self.down drop_table :birdhouses end end
vendor/plugins/yaffle/tasks/yaffle.rake:
namespace :db do namespace :migrate do desc "Migrate the database through scripts in vendor/plugins/yaffle/lib/db/migrate and update db/schema.rb by invoking db:schema:dump. Target specific version with VERSION=x. Turn off output with VERBOSE=false." task :yaffle => :environment do ActiveRecord::Migration.verbose = ENV["VERBOSE"] ? ENV["VERBOSE"] == "true" : true ActiveRecord::Migrator.migrate("vendor/plugins/yaffle/lib/db/migrate/", ENV["VERSION"] ? ENV["VERSION"].to_i : nil) Rake::Task["db:schema:dump"].invoke if ActiveRecord::Base.schema_format == :ruby end end end
11.2. Call migrations directly
vendor/plugins/yaffle/lib/yaffle.rb:
Dir.glob(File.join(File.dirname(__FILE__), "db", "migrate", "*")).each do |file| require file end
db/migrate/20081116181115_create_birdhouses.rb:
class CreateBirdhouses < ActiveRecord::Migration def self.up Yaffle::CreateBirdhouses.up end def self.down Yaffle::CreateBirdhouses.down end end
|
Editor's note: several plugin frameworks such as Desert and Engines provide more advanced plugin functionality. |
11.3. Generate migrations
Generating migrations has several advantages over other methods. Namely, you can allow other developers to more easily customize the migration. The flow looks like this:
-
call your script/generate script and pass in whatever options they need
-
examine the generated migration, adding/removing columns or other options as necessary
This example will demonstrate how to use one of the built-in generator methods named migration_template to create a migration file. Extending the rails migration generator requires a somewhat intimate knowledge of the migration generator internals, so it's best to write a test first:
vendor/plugins/yaffle/test/yaffle_migration_generator_test.rb
require File.dirname(__FILE__) + '/test_helper.rb' require 'rails_generator' require 'rails_generator/scripts/generate' class MigrationGeneratorTest < Test::Unit::TestCase def setup FileUtils.mkdir_p(fake_rails_root) @original_files = file_list end def teardown ActiveRecord::Base.pluralize_table_names = true FileUtils.rm_r(fake_rails_root) end def test_generates_correct_file_name Rails::Generator::Scripts::Generate.new.run(["yaffle_migration", "some_name_nobody_is_likely_to_ever_use_in_a_real_migration"], :destination => fake_rails_root) new_file = (file_list - @original_files).first assert_match /add_yaffle_fields_to_some_name_nobody_is_likely_to_ever_use_in_a_real_migrations/, new_file assert_match /add_column :some_name_nobody_is_likely_to_ever_use_in_a_real_migrations do |t|/, File.read(new_file) end def test_pluralizes_properly ActiveRecord::Base.pluralize_table_names = false Rails::Generator::Scripts::Generate.new.run(["yaffle_migration", "some_name_nobody_is_likely_to_ever_use_in_a_real_migration"], :destination => fake_rails_root) new_file = (file_list - @original_files).first assert_match /add_yaffle_fields_to_some_name_nobody_is_likely_to_ever_use_in_a_real_migration/, new_file assert_match /add_column :some_name_nobody_is_likely_to_ever_use_in_a_real_migration do |t|/, File.read(new_file) end private def fake_rails_root File.join(File.dirname(__FILE__), 'rails_root') end def file_list Dir.glob(File.join(fake_rails_root, "db", "migrate", "*")) end end
|
Editor's note: the migration generator checks to see if a migation already exists, and it's hard-coded to check the db/migrate directory. As a result, if your test tries to generate a migration that already exists in the app, it will fail. The easy workaround is to make sure that the name you generate in your test is very unlikely to actually appear in the app. |
After running the test with rake you can make it pass with:
vendor/plugins/yaffle/generators/yaffle/yaffle_generator.rb
class YaffleMigrationGenerator < Rails::Generator::NamedBase def manifest record do |m| m.migration_template 'migration:migration.rb', "db/migrate", {:assigns => yaffle_local_assigns, :migration_file_name => "add_yaffle_fields_to_#{custom_file_name}" } end end private def custom_file_name custom_name = class_name.underscore.downcase custom_name = custom_name.pluralize if ActiveRecord::Base.pluralize_table_names custom_name end def yaffle_local_assigns returning(assigns = {}) do assigns[:migration_action] = "add" assigns[:class_name] = "add_yaffle_fields_to_#{custom_file_name}" assigns[:table_name] = custom_file_name assigns[:attributes] = [Rails::Generator::GeneratedAttribute.new("last_squawk", "string")] end end end
The generator creates a new file in db/migrate with a timestamp and an add_column statement. It reuses the built in rails migration_template method, and reuses the built-in rails migration template.
It's courteous to check to see if table names are being pluralized whenever you create a generator that needs to be aware of table names. This way people using your generator won't have to manually change the generated files if they've turned pluralization off.
To run the generator, type the following at the command line:
./script/generate yaffle_migration bird
and you will see a new file:
db/migrate/20080529225649_add_yaffle_fields_to_birds.rb
class AddYaffleFieldsToBirds < ActiveRecord::Migration def self.up add_column :birds, :last_squawk, :string end def self.down remove_column :birds, :last_squawk end end
12. Rake tasks
When you created the plugin with the built-in rails generator, it generated a rake file for you in vendor/plugins/yaffle/tasks/yaffle.rake. Any rake task you add here will be available to the app.
Many plugin authors put all of their rake tasks into a common namespace that is the same as the plugin, like so:
vendor/plugins/yaffle/tasks/yaffle.rake
namespace :yaffle do desc "Prints out the word 'Yaffle'" task :squawk => :environment do puts "squawk!" end end
When you run rake -T from your plugin you will see:
yaffle:squawk # Prints out the word 'Yaffle'
You can add as many files as you want in the tasks directory, and if they end in .rake Rails will pick them up.
Note that tasks from vendor/plugins/yaffle/Rakefile are not available to the main app.
13. PluginGems
Turning your rails plugin into a gem is a simple and straightforward task. This section will cover how to turn your plugin into a gem. It will not cover how to distribute that gem.
Historically rails plugins loaded the plugin's init.rb file. In fact some plugins contain all of their code in that one file. To be compatible with plugins, init.rb was moved to rails/init.rb.
It's common practice to put any developer-centric rake tasks (such as tests, rdoc and gem package tasks) in Rakefile. A rake task that packages the gem might look like this:
vendor/plugins/yaffle/Rakefile:
PKG_FILES = FileList[ '[a-zA-Z]*', 'generators/**/*', 'lib/**/*', 'rails/**/*', 'tasks/**/*', 'test/**/*' ] spec = Gem::Specification.new do |s| s.name = "yaffle" s.version = "0.0.1" s.author = "Gleeful Yaffler" s.email =<EMAIL_ADDRESS>s.homepage = "http://yafflers.example.com/" s.platform = Gem::Platform::RUBY s.summary = "Sharing Yaffle Goodness" s.files = PKG_FILES.to_a s.require_path = "lib" s.has_rdoc = false s.extra_rdoc_files = ["README"] end desc 'Turn this plugin into a gem.' Rake::GemPackageTask.new(spec) do |pkg| pkg.gem_spec = spec end
To build and install the gem locally, run the following commands:
cd vendor/plugins/yaffle rake gem sudo gem install pkg/yaffle-0.0.1.gem
To test this, create a new rails app, add config.gem "yaffle" to environment.rb and all of your plugin's functionality will be available to you.
14.  Luckily, writing documentation for your plugin is easy.
The first step is to update the README file with detailed information about how to use your plugin. A few key things to include are:
-
Your name
-
How to install
-
How to add the functionality to the app (several examples of common use cases)
-
Warning, gotchas or tips that might help save users time
Once your README is solid, go through and add rdoc comments to all of the methods that developers will use. It's also customary to add #:nodoc: comments to those parts of the code that are not part of the public api.
Once your comments are good to go, navigate to your plugin directory and run:
rake rdoc
15. Appendix
If you prefer to use RSpec instead of Test::Unit, you may be interested in the RSpec Plugin Generator.

AEW Full Gear: Date, Time, TV, And Live Stream Info
by Brian MaziqueAll-Elite Wrestling has gotten off to a strong start since it debut on TNT in October as a weekly episodic program. One of the things AEW has done well is showcase a good portion of its roster. Expect to see more of that at Full Gear, the promotion’s next pay-per-view.It’s coming up on Saturday and here’s how you can watch.
- Date: November 9, 2019 at 8:00 PM ET (Preshow at 7:00 PM ET)
- Location: Royal Farms Arena, Baltimore, Maryland
- TV: PPV
- Live Stream: B/R Live
The Draw
According to ListenFirst, a social media analytics firm, AEW’s ability to share the focus of their programming and marketing on a variety of talent has helped to sustain a healthy level of interest on social media.
“Nearly a month after All Elite Wrestling: Dynamite debuted on TNT, the initial response has indicated the show is having staying power on social media,” said Tracy David, Chief Marketing Officer at ListenFirst. “Between October 2-31, 2019 the top performing social media video for Dynamite was a barbed wire fight between The Moxley and Omega on Facebook which generated 2,996,751 video views. That's noteworthy because the clip was uploaded on October 17, meaning the social media audience that sampled the first episode has been sticking around. Combined with the fact that the top two performing Dynamite social media videos in the last week were from The Lucha Brothers and SCU fight, as opposed to footage of a more established star like Chris Jericho, is a great sign that Dynamite is starting to develop homegrown stars."
Having fans interested in several storylines helps to increase engagement. AEW has done great work promoting and showcasing its exciting tag-team division. The SCU (C) vs. Private Party vs. The Lucha Brothers – AEW Tag Team Championship match will almost certainly pique fan interest.
That said, the biggest draw on the card will be the AEW Championship match between champion Chris Jericho and Cody. Both men have proven to be capable of top-notch storytelling while still delivering in the ring. Take a listen to this monumental promo from Cody.
Their main event match should be epic.
Here is a look at the entire of the card:
- AEW World Championship - Chris Jericho (c) vs. Cody
- AEW Women’s World Championship - Riho (c) vs. Emi Sakura
- AEW Tag-Team Championship - SCU (Frankie Kazarian and Scorpio Sky) (c) vs. Lucha Bros vs. Private Party
- Unsanctioned Lights Out Match - Jon Moxley vs. Kenny Omega
- The Young Bucks vs. Santana and Ortiz
- "Hangman" Adam Page vs. PAC
- Joey Janela vs. Shawn Spears (with Tully Blanchard)
- The Buy-In Preshow - Britt Baker vs. Bea Priestley
With three titles on the line and a number of other intriguing angles and some likely surprises, Full Gear is set up to be another strong brick in the house AEW is building.


Extending contact form 7
My latest client requested a “careers” section on his website, with the possibility to apply to a particular job offer directly from the description page. A form should be displayed on this page, that simply sends an email to the company’s careers department.
As I developed the website using WordPress and a custom theme, I dug in the excellent contact form 7 plugin and created easily my custom forms.
An obvious requirement: if the careers department receives an email sent from a form on the website, it should contain the job title or reference. However, there is nothing in contact form 7 that allows you to include out of the box such a reference that could be a post custom field or the title of the page.
So I created my own contact form 7 custom input that adds a hidden input field containing the page title – which in my case contains the job description on a position page.
Once you have added the required code, you should see the directly in the generator drop down menu when creating a form, and the syntax to use in your form is as simple as the other tags used by contact form 7:
[pagetitle field_name]
To add support for a hidden page title, simply add a file named pagetitle.php in the contact form 7 modules directory:
contact-form-7 >modules > pagetitle.php
<?php /** ** A base module for [hidden page title] **/ // Shortcode handler wpcf7_add_shortcode( 'pagetitle', 'wpcf7_pagetitle_shortcode_handler', true ); function wpcf7_pagetitle_shortcode_handler( $tag ) { if ( ! is_array( $tag ) ) return ''; $name = $tag['name']; $options = (array) $tag['options']; $values = (array) $tag['values']; $atts = ''; $id_att = ''; $class_att .= ' wpcf7-pagetitle'; foreach ( $options as $option ) { if ( preg_match( '%^id:([-0-9a-zA-Z_]+)$%', $option, $matches ) ) { $id_att = $matches[1]; } } if ( $id_att ) $atts .= ' id="' . trim( $id_att ) . '"'; global $wp_query; $thePostTitle = $wp_query->post->post_title; $value = $thePostTitle; $html = '<input name="'.$name.'" type="hidden" value="' . esc_attr( $value ) . '"' . $atts . ' />'; return $html; } // Tag generator add_action( 'admin_init', 'wpcf7_add_tag_generator_pagetitle', 50 ); function wpcf7_add_tag_generator_pagetitle() { wpcf7_add_tag_generator( 'pagetitle', __( 'Hidden page title', 'wpcf7' ), 'wpcf7-tg-pane-pagetitle', 'wpcf7_tg_pane_pagetitle' ); } function wpcf7_tg_pane_pagetitle( &$contact_form ) { ? >
 <form action="">

<?php echo esc_html( __( 'Name', 'wpcf7' ) ); ?>
<input type="text" name="name" class="tg-name oneline" />

 id (<?php echo esc_html( __( 'optional', 'wpcf7' ) ); ?>)
 <input type="text" name="id" class="idvalue oneline option" />	 class (<?php echo esc_html( __( 'optional', 'wpcf7' ) ); ?>)
 <input type="text" name="class" class="classvalue oneline option" />

<?php echo esc_html( __( "Copy this code and paste it into the form left.", 'wpcf7' ) ); ?>
<input type="text" name="pagetitle" class="tag" readonly="readonly" onfocus="this.select()" />

<?php echo esc_html( __( "And, put this code into the File Attachments field below.", 'wpcf7' ) ); ?>
⬇ <input type="text" class="mail-tag" readonly="readonly" onfocus="this.select()" />
 </form>
 <?php } ?>
Enjoy!

OT: You do program Ruby and PHP. What's wrong with Python then? ;)
Matt Sun, 12 Sep 2010 - 13:59
@Detronizator: Did I ever say anything about python being wrong? =D
Dan Sun, 31 Oct 2010 - 11:06
Hi I tried using this addon but it didn't work I added this code in the form area: [pagetitle field_name] and this code in the message area: [field_name] Any ideas what am I doing wrong? Thanks, Dan
Matt Sun, 31 Oct 2010 - 11:12
Dan, the code you wrote and the places you put them seem correct. Did you add the code above in a pagetitle.php file in the contact-form-7 plugin modules directory as explained in the post above? If you did, try deactivating the plugin and reactivating it again.
Dan Sun, 31 Oct 2010 - 11:19
WOW! what a speedy reply. I reactivated the plugin as you said and now it works Thanks alot Dan
Matt Sun, 31 Oct 2010 - 11:23
No probs, glad it works for you!
Aure Mon, 01 Aug 2011 - 11:23
Hi, good job m8. It was fine until I upgraded my CF7 plugin to 2.4.6 version. Now "Hidden page title" gone from dropdown menu :\
Matt Thu, 18 Aug 2011 - 11:11
Hi Aure, The problem you have is that I haven't submitted my change to the official plugin, so when you updated CF7, the change you have done simply disappeared. I'll try to contact the plugin author see if this can be integrated! Until then you will have to apply the change again I'm afraid.
Matt Fri, 19 Aug 2011 - 09:58
Aure, the author of the plugin pointed me towards this http://wordpress.org/extend/plugins/contact-form-7-modules/ I haven't tried it yet, but it certainly looks on paper to do what I needed when I extended CF7 in the first place! You might want to give it a go!
Miriam de Paula Wed, 01 Feb 2012 - 21:47
Hi ... I'm having the same problem as Dan: http://blog.ekynoxe.com/2010/09/06/extending-contact-form-7/#div-comment-762 Please, somebody help me? The extra field data are not sent in the mail .... =(
Matt Wed, 01 Feb 2012 - 22:02
Hi Miriam, which version of WPCF7 are you using? It seems there is support for a hidden field now. If you are still using an older version and try to implement the change documented above, have you uninstalled and re-installed the plugin like Dan did? It solved his problem apparently.
Miriam de Paula Wed, 01 Feb 2012 - 22:48
Hi Matt... Thanks for responding. I created a field that lists posts from custom post type. It is working. But I can not send the selected data in the email. What I did wrong?
Miriam de Paula Wed, 01 Feb 2012 - 22:56
Hi Matt. Very Thank you! I looked at the plugin's version, and there was an update (3.1). After upgrading, I got to the extra field work! Thank you! Thank you! =)

| Prev | Up | Chapter 50. Genetic Query Optimizer | Next |
Among all relational operators the most difficult one to process and optimize is the join. The number of possible query plans grows exponentially with the number of joins in the query. Further optimization effort is caused by the support of a variety of join methods (e.g., nested loop, hash join, merge join in PostgreSQL) to process individual joins and a diversity of indexes (e.g., B-tree, hash, GiST and GIN in PostgreSQL) as access paths for relations.
The normal PostgreSQL query optimizer performs a near-exhaustive search over the space of alternative strategies. This algorithm, first introduced in IBM's System R database, produces a near-optimal join order, but can take an enormous amount of time and memory space when the number of joins in the query grows large. This makes the ordinary PostgreSQL query optimizer inappropriate for queries that join a large number of tables.
The Institute of Automatic Control at the University of Mining and Technology, in Freiberg, Germany, encountered some problems when it wanted to use PostgreSQL as the backend for a decision support knowledge based system for the maintenance of an electrical power grid. The DBMS needed to handle large join queries for the inference machine of the knowledge based system. The number of joins in these queries made using the normal query optimizer infeasible.
In the following we describe the implementation of a genetic algorithm to solve the join ordering problem in a manner that is efficient for queries involving large numbers of joins.


SMTP Connection
SMTP client module to connect to SMTP servers and send mail with it.
This module is the successor for the client part of the (now deprecated) SMTP module simplesmtp. For matching SMTP server see smtp-server.
Usage
Step 1. Install Nodemailer with npm
smtp-connection is exposed as a submodule of Nodemailer
npm install nodemailer --save
Step 2. Require smtp-connection in your script
const SMTPConnection = require("nodemailer/lib/smtp-connection");
Step 3. Create SMTPConnection instance
let connection = new SMTPConnection(options);
Where
Events
SMTPConnection instances are event emitters with the following events
- ‘error’ (err) emitted when an error occurs. Connection is closed automatically in this case.
- ‘connect’ emitted when the connection is established
- ‘end’ when the instance is destroyed
connect
Establish the connection
connection.connect(callback);
Where
- callback is the function to run once the connection is established. The function is added as a listener to the ‘connect’ event.
After the connect event the connection has the following properties:
- connection.secure - if true then the connection uses a TLS socket, otherwise it is using a cleartext socket. Connection can start out as cleartext but if available (or requireTLS is set to true) connection upgrade is tried
login
If the server requires authentication you can login with
connection.login(auth, callback);
Where
send
Once the connection is authenticated (or just after connection is established if authentication is not required), you can send mail with
connection.send(envelope, message, callback);
Where
-
envelope is the envelope object to use
- envelope.from is the sender address
- envelope.to is the recipient address or an array of addresses
- envelope.size is an optional value of the predicted size of the message in bytes. This value is used if the server supports the SIZE extension (RFC1870)
- envelope.use8BitMime if true then inform the server that this message might contain bytes outside 7bit ascii range
- envelope.dsn is the dsn options
- envelope.dsn.ret return either the full message ‘FULL’ or only headers ‘HDRS’
- envelope.dsn.envid sender’s ‘envelope identifier’ for tracking
- envelope.dsn.notify when to send a DSN. Multiple options are OK - array or comma delimited. NEVER must appear by itself. Available options: ‘NEVER’, ‘SUCCESS’, ‘FAILURE’, ‘DELAY’
- envelope.dsn.orcpt original recipient
-
message is either a String, Buffer or a Stream. All newlines are converted to \r\n and all dots are escaped automatically, no need to convert anything before.
-
callback is the callback to run once the sending is finished or failed. Callback has the following arguments
- err and error object if sending failed
- err.code string code identifying the error, for example ‘EAUTH’ is returned when authentication fails
- err.response is the last response received from the server (if the error is caused by an error response from the server)
- err.responseCode is the numeric response code of the response string (if available)
- info information object about accepted and rejected recipients
- info.accepted an array of accepted recipient addresses. Normally this array should contain at least one address except when in LMTP mode. In this case the message itself might have succeeded but all recipients were rejected after sending the message.
- info.rejected an array of rejected recipient addresses. This array includes both the addresses that were rejected before sending the message and addresses rejected after sending it if using LMTP
- info.rejectedErrors if some recipients were rejected then this property holds an array of error objects for the rejected recipients
- info.response is the last response received from the server
quit
Use it for graceful disconnect
close
Use it for less graceful disconnect
reset
Use it to reset current session (invokes RSET command)
connection.reset(callback);
