class Concurrent::Promises::Future
Represents a value which will become available in future. May reject with a reason instead, e.g. when the tasks raises an exception.
Public Instance Methods
Creates a new event which will be resolved when the first of receiver, `event_or_future` resolves. Returning future will have value nil if event_or_future is event and resolves first.
@return [Future]
# File lib/concurrent/promises.rb, line 1074 def any(event_or_future) AnyResolvedFuturePromise.new_blocked_by2(self, event_or_future, @DefaultExecutor).future end
@!visibility private
# File lib/concurrent/promises.rb, line 1204 def apply(args, block) internal_state.apply args, block end
Creates new future dependent on receiver which will not evaluate until touched, see {#touch}. In other words, it inserts delay into the chain of Futures making rest of it lazy evaluated.
@return [Future]
# File lib/concurrent/promises.rb, line 1084 def delay event = DelayPromise.new(@DefaultExecutor).event ZipFutureEventPromise.new_blocked_by2(self, event, @DefaultExecutor).future end
Allows rejected Future
to be risen with `raise` method. If the reason is not an exception `Runtime.new(reason)` is returned.
@example
raise Promises.rejected_future(StandardError.new("boom")) raise Promises.rejected_future("or just boom")
@raise [Concurrent::Error] when raising not rejected future @return [Exception]
# File lib/concurrent/promises.rb, line 1002 def exception(*args) raise Concurrent::Error, 'it is not rejected' unless rejected? raise ArgumentError unless args.size <= 1 reason = Array(internal_state.reason).flatten.compact if reason.size > 1 ex = Concurrent::MultipleErrors.new reason ex.set_backtrace(caller) ex else ex = if reason[0].respond_to? :exception reason[0].exception(*args) else RuntimeError.new(reason[0]).exception(*args) end ex.set_backtrace Array(ex.backtrace) + caller ex end end
Creates new event which will be resolved when the returned event by receiver is. Be careful if the receiver rejects it will just resolve since Event
does not hold reason.
@return [Event]
# File lib/concurrent/promises.rb, line 1119 def flat_event FlatEventPromise.new_blocked_by1(self, @DefaultExecutor).event end
Creates new future which will have result of the future returned by receiver. If receiver rejects it will have its rejection.

# File lib/concurrent/promises.rb, line 970 def result(timeout = nil) internal_state.result if wait_until_resolved timeout end
Allows to use futures as green threads. The receiver has to evaluate to a future which represents what should be done next. It basically flattens indefinitely until non Future
values is returned which becomes result of the returned future. Any encountered exception will become reason of the returned future.
@return [Future] @param [#call(value)] run_test
an object which when called returns either Future to keep running with or nil, then the run completes with the value. The run_test can be used to extract the Future from deeper structure, or to distinguish Future which is a resulting value from a future which is suppose to continue running.
@example
body = lambda do |v| v += 1 v < 5 ? Promises.future(v, &body) : v end Promises.future(0, &body).run.value! # => 5
# File lib/concurrent/promises.rb, line 1199 def run(run_test = method(:run_test)) RunFuturePromise.new_blocked_by1(self, @DefaultExecutor, run_test).future end

Visualizing Using Python Commands¶
The following tutorial assumes you are familiar with visualizing using the GUI.
Before starting:¶
- Load Blender with the BlenderNEURON add-on (NEURON tab should be visible in Blender left panel)
- Load your model in NEURON
- Load BlenderNEURON in NEURON by running
from blenderneuron.quick import bn
- Test the connectivity between NEURON and Blender with
bn.is_blender_ready()
(Should say “True”)
See Installation for how to install the python library and the Blender addon.
Visualizing Morphology¶
Follow these steps to visualize the cell morphology of a NEURON model:
- Once your model is loaded, run bn.to_blender()
- A moment later, your model should appear in Blender
- Navigate around the Blender scene to inspect the model. If you’re not familiar with Blender, these tutorials will give an overview of basic scene navigation.
By default, BlenderNEURON will export the morphology of all cells (sections) in the model. It will use NEURON’s x/y/z3d() and diam3d() values to build the 3D meshes in Blender.
In within Blender, 1 cm is set to correspond to 1 micron in NEURON.
If you add or make changes to your model’s sections/cells, run bn.refresh() before running bn.to_blender() to ensure that the changes are included in the export.
For a more detailed control of the export process, see the client library API
A complete example of exporting a model to Blender:
from blenderneuron.quick import bn # import the BlenderNEURON library
assert bn.is_blender_ready() # check if communication with Blender can be established
#bn.refresh() # uncomment this if there has been a model change since last run
bn.to_blender() # send section morphology data to Blender
Visualizing Activity¶
Follow these steps to visualize the morphology and simulated activity of a NEURON model:
- Once your model is loaded, run bn.prepare_for_collection(). This will add a handler to gather section voltage values during the simulation.
- Run your simulation (e.g. h.run())
- Once the simulation is finished, run bn.to_blender()
- A moment later, your model should appear in Blender
- Use the buttons under the bottom timeline in Blender to re-play the simulation. If your cells emit action potentials (Vm > -20mV), you should be able to see them as glowing compartments. By default, 1 frame in Blender corresponds to 0.5ms in NEURON.
- You can scrub the timeline to re-play any part of the simulation and use the left/right arrow keys to step through the frames.
A complete example of exporting a model with activity to Blender:
from blenderneuron.quick import bn # import the BlenderNEURON library
assert bn.is_blender_ready() # check if communication with Blender can be established
bn.prepare_for_collection() # adds a NEURON handler to collect section activity data
#bn.refresh() # uncomment this if there has been a model change since last run
h.run() # run the simulation
bn.to_blender() # send section morphology and activity data to Blender
Customizing Visualization Parameters¶
The default visualization parameters used by bn.to_blender() method can be customized. Each visualization group, composed of cell root sections, can have its own visualization parameters. By default one group, all, is created and contains the root sections of all cells in the model.
Groups are stored in the bn.groups dictionary. To customize the default group’s parameters, use the example script below.
In this example, the render detail of each cell will be reduced to improve performance (fewer polygons) in Blender:
# Build and prepare your model
prepare_model()
# import BlenderNEURON
from blenderneuron.quick import bn
# Create the default "all" group. Accessible with `bn.groups['all']`
bn.setup_default_group()
# The whole group of cells is treated as one selectable Blender object (use 'Cell' to make cells individually selectable)
bn.groups['all']['3d_data']['interaction_level'] = 'Group'
# Each cell will get its own color (each cell will have it's own Blender material)
bn.groups['all']['3d_data']['color_level'] = 'Cell'
# Section compartments will be connected with straight-line cylinders (instead of curvy beziers)
bn.groups['all']['3d_data']['smooth_sections'] = False
# Extra subdivisions are not necessary for straight-line cylinders
bn.groups['all']['3d_data']['segment_subdivisions'] = 1
# The cylinders will have pentagonal cross sections
bn.groups['all']['3d_data']['circular_subdivisions'] = 5
# Send all groups with the updated parameters to Blender
bn.to_blender()
See documentation of the create_cell_group method for values of other parameters.

MapCalibration The MapCalibration app's aim is to assist satnav-based navigation for maps without GPS coordinates. The main idea is to calibrate the map by setting reference markers on a satellite photo map, in locations easy to identify on both maps. Then, the app computes the map scale. From now on, an user can identify locations on the calibrated map by measuring distances from reference markers. Types of markers In detail, there are the following types of markers (colors correspond to colors of respective markers): Reference markers reference marker - specified by the marker on the photo map or gps coordinates.
Syntax highlighting and menus can be configured via config.toml
.
Example In the example we will show how a location in the terrain can be found on the basis of its identification on the map we are given. Below we present the steps to be performed: The map we use Assume that we are given the following map (either electronic or printed on the paper). The units we use for measuging distances are relevant only for the scale (proportion of distance on the map and distance in the terrain). When we do not care about the scale, we can use any units (pixels, centimeters, milimeters, inches, etc). The reference point We choose the first reference point at the intersection (a location easy to identify both on the map and in the sat photo).

This superb castle is located on elevated ground beside the river at the south-eastern end of the city. The castle was built in the thirteenth century on the site of an earlier fort. The Butlers, the Earls of Ormonde (an Hibernicised Norman clan), occupied the castle from the fourteenth century onwards. In modern times, the castle has been restored to its former glory by the state, and was officially open to the public in 1976. There is an exhibition hall open to the public in the Old Castle Stables.
St. Canice's was erected in the thirteenth century, and is accessible from Irishtown via St. Canice's Steps. The cathedral features a magnificent tower that offers impressive views of the city. The cathedral evolved over the centuries and was unfortunately damaged by Oliver Cromwell's troops in the seventeenth century. This Kilkenny landmark features a fascinating collection of monuments and tombs dating from the Tudor era.
Located in the heart of Kilkenny City, there's no better place to plan your trip around Ireland's Ancient East than from here in the unforgettable setting of Kilkenny's Medieval Mile. You'll find the Smithwhicks Brewery in the heart of this beautiful city. They are less than a 10 minute stroll from the iconic Kilkenny Castle, and are very proud to be part of Kilkenny's famous Medieval Mile.
This magnificent sixteenth century Tudor town house is situated on Parliament Street. Built in 1594 by John Rothe, the building consists of three houses with courtyards. Rothe House currently houses the museum and library of the Kilkenny Archaeological Society. Within the museum there are a number of exhibits including period costume displays and a genealogical centre.
A well-developed Show Cave and exhibition centre. Admission is by guided tour only. Open 7 days a week until 31st Oct. with tours commencing at 9.30am. During winter months tours only on Saturdays, Sundays and Bank Holidays or by appointment.
Shee Alms House is situated in Rose Inn Street and was founded in 1582 by Sir Richard Shee. The purpose of these institutions was to take care of the poor, and this Tudor Alms House is one of the last remaining buildings of its type still in existence in Ireland. The building has been recently restored and now accommodates the Kilkenny Tourist Office.
80-acre activity park with walking trails, kids' play areas, fishing lakes and a canopy walkway.

This is a fork of a great library when-switch which seems no longer maintained.
You can convert a ts-when use in a functional way, using a single expression:
import when from 'ts-switch'
const getDrinkPrice = drink =>
when(drink)
.is('Coke', 1.5)
.is('Pepsi', 1.8)
.else(2.0)
You can return a value when given assertion is correct
const x = when
.true(someVariable === true, "some variable is true")
.else("some variable is false")
You can use match
method with any object exposing a test
method.
const getCaseStyle = text =>
when(text)
.match(/^([A-Z][a-z]*)+$/, 'UpperCamelCase')
.match(/^([a-z]+[A-Z][a-z]*)+$/, 'LowerCamelCase')
.match(/^([a-z]+_[a-z]+)+$/, 'SnakeCase')
.else('Unknown')
type SpaceObject = { x: number; y: number; z: number }
type Cube = SpaceObject & { width: number }
type Sphere = SpaceObject & { radius: number }
const SpaceObjectSchema = {
test: (_: any): _ is SpaceObject =>
typeof _.x === 'number' &&
typeof _.y === 'number' &&
typeof _.z === 'number'
}
const CubeSchema = {
test: (_: any): _ is Cube =>
typeof _.width === 'number' && SpaceObjectSchema.test(_)
}
const SphereSchema = {
test: (_: any): _ is Sphere =>
typeof _.radius === 'number' && SpaceObjectSchema.test(_)
}
const getObjectVolume = (object: SpaceObject) =>
// Each match handler will receive correct static type
when(object)
.match(CubeSchema, cube => cube.width ** 3)
.match(SphereSchema, sphere => Math.PI * 3 / 4 * sphere.radius ** 3)
.else(_ => null)
match
andis
can both be used in the samewhen
expression.
when
is fully compatible with TypeScript, and will check the types you return in each is
expression:
const getDrinkPrice = (drink: 'Pepsi' | 'Coke' | 'Orangina'): number =>
when(drink)
.is('Coke', 1.5)
.is('Pepsi', 1.8)
.else(2.0)
Here the return type of the when
expression will be number
For each is
or else
expression added to the current when
expression, the type is added as an union to the previous type.
const getDrinkPrice = (drink: 'Pepsi' | 'Coke' | 'Orangina') =>
when(drink)
.is('Coke', 1.5)
.is('Pepsi', true)
.else('Free')
Here the return type of getDrinkPrice
expression will be number | string | boolean

Egg and bacon is a match made in heaven. This pie from The Hairy Bikers is quick, easy and delicious served warm or cold.
To make the filling, heat the oil in a large non-stick frying pan.
Cut the bacon rashers in half and fry over a medium heat for 4–5 minutes until the fat is golden and crisp, turning them once.
Remove the bacon from the heat and leave to cool. Place a sturdy baking tray in the oven and preheat to 190C/375F/Gas 5.
For the pastry, pulse the flour, salt and butter in a food processor until the mixture resembles fine breadcrumbs.
Whisk the egg with a tablespoon of cold water and pour onto the flour and butter mixture with the motor running. Continue blending until the dough begins to form a ball.
Turn the pastry out onto a lightly floured board, knead quickly into a ball and cut in half.
Roll out one half until it is about 0.5cm/¼in thick and line a greased 23cm/9in pie plate, leaving any excess pastry overhanging the edge.
Scatter the bacon loosely over the pastry case. Gently break six of the eggs into the pastry case, spacing them evenly between the bacon rashers.
Beat the remaining eggs with the milk and plenty of salt and pepper.
Slowly pour the beaten eggs into the pastry case, stopping every now and then to allow the beaten egg to find its way between the whole eggs and the bacon. Leave 2–3 tablespoons of the mixture in the bowl for glazing the top of the pie.
Roll out the rest of the pastry to make a lid for the pie. Brush the edge of the pastry case with beaten egg and milk and gently lift the pastry lid over the filling.
Press the edges firmly to seal, then trim. Use a fork to firmly seal the edge all the way around the pie then brush the top with the remaining beaten egg to glaze.
Bake the pie on the preheated baking tray for 45–55 minutes until golden-brown and cooked through.
Test by piercing the centre with a sharp knife – the filling should be just set. If it’s still runny, put the pie back in the oven for a few minutes. Leave to stand for at least 15 minutes before serving.


Challenges have made Insolvency and Bankruptcy Code stronger: IBBI chief
The code came into force in December 2016 and the first resolution case was approved in August 2017
by Press Trust of IndiaPrompt course corrections have been done to the insolvency law to address the needs of stakeholders, IBBI chief M S Sahoo said on Monday as he emphasised that challenges have made the legislation stronger.
The Insolvency and Bankruptcy Board of India (IBBI) is responsible for implementing the Insolvency and Bankruptcy Code (IBC).
Sahoo said the impact of the code should not be seen just in terms of things under it, but also "on account as well as shadow" of the law.
There have been instances of dues getting settled before a corporate was to be dragged into insolvency process.
"Prompt course corrections" have been done to the code, the IBBI Chairperson said and stressed that, with challenges, the law has become stronger.
The code came into force in December 2016 and the first resolution case was approved in August 2017.
Since its implementation, many provisions of the code have been challenged and the government has also carried out various amendments to the law, including barring defaulting promoters from taking back control of the company after insolvency process.
He was speaking at a conference on 'Resolving Insolvency in India' organised by industry body CII.

it is an information system on the Internet that allows documents to be connected to other documents by hypertext links, enabling the user to search for information by moving from one document to another.
HTML - Hypertext Markup Languagea standardized system for tagging text files to achieve font, color, graphic, and hyperlink effects on World Wide Web pages.
Tagsare the hidden keywords within a web page that define how the browser must format and display the content. Most tags must have two parts, an opening and a closing part. You can determine the closing tag because it has a slash.
 This makes them very unforgiving since a small mistake by a programmer can cause huge problems in a program.

First, make sure that VFWarmup
and ACHR.cu
are correctly installed.
Sampling of Ecoli core¶
Sampling is a two-step process. First, let’s generate the warmup points for sampling using VFWarmup
mpirun -np 1 --bind-to none -x OMP_NUM_THREADS=4 createWarmupPts ecoli_core.mps
Make sur you pick a number of warmup points greater than 95*2=190, say 200 for instance. The output has been written to ecoli_core200warmup.csv
Then, let’s sample the solution space of Ecoli core metabolic model starting from the warmup points generated previously:
./ACHR model.mps ecoli_core200warmup.csv 2 1000 1000
We will generate 2 files contatining each 1000 points. Each points has converged after 1000 step. The total number of points generated is 2*1000=2000.

Iterating quickly might mean the difference between meeting your market window and permanently missing an opportunity. You might be grappling with large amounts of data that make development unwieldy. You have the idea that you can structure your data in a graph, but how?
Using XN Logic’s platform helps you get business logic into your data, structure it, and develop functioning applications—quickly.
Not having the right expertise on hand when you need it can cause you to miss your market window. Even well-managed development projects can fail. You have the data to create applications. The question is: How to use it? You might understand that graph databases offer tremendous potential but how can this technology work for you?
As the creators of Pacer, the first truly expressive graph traversal library written in any existing programming language, XN Logic applies a deep understanding of graph-related problems in low-level graph traversal to application architecture. You can expect not only faster development approaches and graph database queries from us but also dispassionate advice on the best solutions to your technical problems. We give you the end-to-end expertise you need for success. By presenting information how you want to see it, we can get you up and running—in weeks as opposed to months—with a full-featured application, that includes security, a user interface, and easy integration into your product suite.
You can spend a lot of time figuring out which graph database approach to take. We can help you navigate the variety of tools and techniques available for different purposes, and for the programming languages your team uses. We understand the difference between an online transaction processing (OLTP) system and a tool for offline data analysis—and the different graph techniques they require.
At XN Logic we’re enmeshed in the graph community and familiar with the range of products on offer. Our open-source query language, Pacer, enables easy to migration to our graph database of choice, Neo4j. With Pacer’s high-performance queries you can:
Expressive and simple to understand, Pacer facilitates getting info in and out, and building applications that use that information.
Take a look at our graph database development case studies.
You can complete projects more efficiently if you not only know the right tools but also how to use them. While building the XN Logic framework, we've worked with Neo4j, Orient, and Dex graph databases and understand their unique pros and cons. We also understand where a key-value store, a document store, or a relational database might be a better fit for your requirements. We know how to tie your graph database to an alternate type of data store to achieve your project’s goals. We achieve all of this cleanly with our proven toolset.
Our two-step business process:
This dramatically shrinks the time spent doing boilerplate API and UI tasks.
A graph is the perfect way to model your data. When you draw out a concrete example of your data for someone, what you draw is a graph. It is the natural way you express your data. When we work with you to model your data, most of the effort can be devoted to simply describing it. Ask us how we can help you translate your description directly to a graph data model. From there it’s a small step to a functioning application that you can iterate, rapidly.
Typically APIs are very static, and they often require re-programming. The XN Logic API is extensible, allowing you to build out URLs in any valid way because of its ability to retain context. So, with any standard requests already in the system, this means you can just keep adding requests in an existing context. As a result, you save time building on the existing things that teams typically spend time on, freeing you up to do more sophisticated tasks that add the most value to your business.
Check out this example of our API in action. Note how it accomplishes in a few lines of declaration something that would normally require many more lines of code and exponentially more effort.
XN Logic’s framework includes the HistoryGraph which lets you run ad-hoc queries on your system in real-time to generate a comprehensive analysis of that system at any point of its existence. Usually that kind of information is static—dumped to a record—and requires pre-processing, plus the involvement of other people. The HistoryGraph eliminates that and is non-resource-intensive.

The latest data for the Currencies Forecast Poll, released by FXStreet on Friday the 3rd shows a distribution of 60.33% short-term Bearish among the 15 participants.
Highlighted comments
-
If the NFP is a strong figure today, then the dollar’s run to higher ground will resume and the Euro will head back to 1.2300 and today’s session low at 1.2287
-
After a steep fall, the Euro will attempt to recover losses against the Dollar. However, this will be limited to 1.10 and we would need to close above this level for the sentiment to be more bullish.
-
Despite a near term rebound, the bears are back I control and this should continue to put pressure on the supports over the coming weeks.
The Currencies Forecast Poll is a sentiment tool that highlights our selected experts near and medium term mood and calculates trends according to Friday's 15:00 GMT price. The #FXpoll is not to be taken as signal or as final target, but as an exchange rates heat map of where sentiment and expectations are going.

FUNCTION DLANEG( N, D, LLD, SIGMA, PIVMIN, R ) IMPLICIT NONE INTEGER DLANEG * * -- LAPACK auxiliary routine (version 3.1) -- * Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd.. * November 2006 * * .. Scalar Arguments .. INTEGER N, R DOUBLE PRECISION PIVMIN, SIGMA * .. * .. Array Arguments .. DOUBLE PRECISION D( * ), LLD( * ) * .. * * Purpose * ======= * * DLANEG computes the Sturm count, the number of negative pivots * encountered while factoring tridiagonal T - sigma I = L D L^T. * This implementation works directly on the factors without forming * the tridiagonal matrix T. The Sturm count is also the number of * eigenvalues of T less than sigma. * * This routine is called from DLARRB. * * The current routine does not use the PIVMIN parameter but rather * requires IEEE-754 propagation of Infinities and NaNs. This * routine also has no input range restrictions but does require * default exception handling such that x/0 produces Inf when x is * non-zero, and Inf/Inf produces NaN. For more information, see: * * Marques, Riedy, and Voemel, "Benefits of IEEE-754 Features in * Modern Symmetric Tridiagonal Eigensolvers," SIAM Journal on * Scientific Computing, v28, n5, 2006. DOI 10.1137/050641624 * (Tech report version in LAWN 172 with the same title.) * * Arguments * ========= * * N (input) INTEGER * The order of the matrix. * * D (input) DOUBLE PRECISION array, dimension (N) * The N diagonal elements of the diagonal matrix D. * * LLD (input) DOUBLE PRECISION array, dimension (N-1) * The (N-1) elements L(i)*L(i)*D(i). * * SIGMA (input) DOUBLE PRECISION * Shift amount in T - sigma I = L D L^T. * * PIVMIN (input) DOUBLE PRECISION * The minimum pivot in the Sturm sequence. May be used * when zero pivots are encountered on non-IEEE-754 * architectures. * * R (input) INTEGER * The twist index for the twisted factorization that is used * for the negcount. * * Further Details * =============== * * Based on contributions by * Osni Marques, LBNL/NERSC, USA * Christof Voemel, University of California, Berkeley, USA * Jason Riedy, University of California, Berkeley, USA * * ===================================================================== * * .. Parameters .. DOUBLE PRECISION ZERO, ONE PARAMETER ( ZERO = 0.0D0, ONE = 1.0D0 ) * Some architectures propagate Infinities and NaNs very slowly, so * the code computes counts in BLKLEN chunks.

My time at Virtual Lab, during my final semester as an undergraduate, was extremely rewarding. I loved that I could start my day with no schedule, and by the end of it I had took part in the interview process for summer interns. Not only have I gained understanding of how CSR works; I now have an idea of how it is differrent from the life of ours.
The day I was asked to go to a village under my Rural Area Work Experience (RAWE), village internship program as a part of my degree program B Sc. (IT), I was very sad initially not because there would be work, but because it was difficult for me to stay in a village for such a long time as I was used to an urban lifestyle. But when I went and stayed there for a few weeks, I realized there were changes in myself. It helped me in growing myself a lot.
I have interned at Virtual Labfor the past two summers. That's how good it is! I worked on a variety of projects, each of which increased my understanding of global public education issues. I saw how NGO adapts its approaches to the particulars of each context, the better to assure that programs meet the needs of those they serve.But what I enjoyed most, and what has solidified my desire to pursue a career in public education, are the inspiring and generous people who I met and worked with during my internship. The internship with rural people in the area helped me in finding my way, it helped me to think what I actually want which will not only satisfy me but will satisfy the society as well. It helped me in developing an insight and interest, which was buried deep inside my heart. I was able to recognize my inclination for society and its people and thus I decided to join them. India is endowed with maximum human resource and if the available resources is best utilized whether in educationor any other sector, the day is not far when India will also be among the developed nations.

Polymorphic URL helpers are methods for smart resolution to a named route call when given an Active Record model instance. They are to be used in combination with ActionController::Resources.
These methods are useful when you want to generate correct URL or path to a RESTful resource without having to know the exact type of the record in question.
Nested resources and/or namespaces are also supported, as illustrated in the example:
polymorphic_url([:admin, @article, @comment])
results in:
admin_article_comment_url(@article, @comment)
Usage within the framework
Polymorphic URL helpers are used in a number of places throughout the Rails framework:
- url_for, so you can use it with a record as the argument, e.g. url_for(@article);
- ActionView::Helpers::FormHelper uses polymorphic_path, so you can write form_for(@article) without having to specify :url parameter for the form action;
- redirect_to (which, in fact, uses url_for) so you can write redirect_to(post) in your controllers;
- ActionView::Helpers::AtomFeedHelper, so you don‘t have to explicitly specify URLs for feed entries.
Prefixed polymorphic helpers
In addition to polymorphic_url and polymorphic_path methods, a number of prefixed helpers are available as a shorthand to :action => "…" in options. Those are:
- edit_polymorphic_url, edit_polymorphic_path
- new_polymorphic_url, new_polymorphic_path
Example usage:
edit_polymorphic_path(@post) # => "/posts/1/edit" polymorphic_path(@post, :format => :pdf) # => "/posts/1.pdf"
[ show source ]
# File vendor/rails/actionpack/lib/action_controller/polymorphic_routes.rb, line 142 142: def formatted_polymorphic_path(record_or_hash, options = {}) 143: ActiveSupport::Deprecation.warn("formatted_polymorphic_path has been deprecated. Please pass :format to the polymorphic_path method instead", caller) 144: options[:format] = record_or_hash.pop if record_or_hash === Array 145: polymorphic_url(record_or_hash, options.merge(:routing_type => :path)) 146: end
[ show source ]
# File vendor/rails/actionpack/lib/action_controller/polymorphic_routes.rb, line 136 136: def formatted_polymorphic_url(record_or_hash, options = {}) 137: ActiveSupport::Deprecation.warn("formatted_polymorphic_url has been deprecated. Please pass :format to the polymorphic_url method instead", caller) 138: options[:format] = record_or_hash.pop if Array === record_or_hash 139: polymorphic_url(record_or_hash, options) 140: end
Returns the path component of a URL for the given record. It uses polymorphic_url with :routing_type => :path.
[ show source ]
# File vendor/rails/actionpack/lib/action_controller/polymorphic_routes.rb, line 114 114: def polymorphic_path(record_or_hash_or_array, options = {}) 115: options[:routing_type] = :path 116: polymorphic_url(record_or_hash_or_array, options) 117: end
Constructs a call to a named RESTful route for the given record and returns the resulting URL string. For example:
# calls post_url(post) polymorphic_url(post) # => "http://example.com/posts/1" polymorphic_url([blog, post]) # => "http://example.com/blogs/1/posts/1" polymorphic_url([:admin, blog, post]) # => "http://example.com/admin/blogs/1/posts/1" polymorphic_url([user, :blog, post]) # => "http://example.com/users/1/blog/posts/1"
Options
- :action - Specifies the action prefix for the named route: :new or :edit. Default is no prefix.
- :routing_type - Allowed values are :path or :url. Default is :url.
Examples
# an Article record polymorphic_url(record) # same as article_url(record) # a Comment record polymorphic_url(record) # same as comment_url(record) # it recognizes new records and maps to the collection record = Comment.new polymorphic_url(record) # same as comments_url()

National Grid beats half year expectations amid New York dispute
by Edward ThicknesseUK energy supplier National Grid used its half year results to say that it is “confident” it would be able to address issues raised in a letter from New York governor Andrew Cuomo earlier this week.
The company is facing the risk of losing its license to operate its gas franchise in New York City and Long Island, with Cuomo having said this month that it had failed to provide “adequate and reliable service.”

The figures
Underlying profit before tax for the year to date fell four per cent to £785m, from £816m in 2018, but was above the £748m that analysts had expected.
Earnings per share rose two per cent to 20p.
National Grid reported that capital investment had risen to £2.7bn, driven by an increase in US expenditure and the acquisition of Geronimo, a US clean energy provider.
The Warwick-headquartered firm also announced proceeds of nearly £2bn from the sale of its 39 per cent stake in the Cadent Gas Networks.
Why it’s interesting
The FTSE 100 company, which runs Britain’s energy systems, has had a tricky year, with problems in New York compounded by an investigation over widespread outages in the UK over the summer.
The blackout, which was caused by a lightning strike in August, left more than one million customers including homes, businesses, a hospital and Newcastle Airport without power.
The company said it would continue to work closely with Ofgem and Beis in their investigations, adding: “We do not underestimate the disruption and inconvenience this caused.”
National Grid also announced that it had set a new target of reaching net zero emissions by 2050, up from its current target of 80 per cent.

National Grid said the objective will be supported by other work such as further energy efficiency programmes and renewable natural gas programmes.
What National Grid said
Chief executive John Pettigrew said: “In the first half of this year we have delivered solid financial performance and continued to deliver strong organic growth at the top end of the 5 to 7% range.
“We also made good progress on our strategic priorities, including agreeing a multi-year, forward rate case in Massachusetts Electric, submitting our draft business plans for RIIO-2 in the UK and completed our acquisition of Geronimo.
“In the second half, we are progressing our priorities across the Group including addressing the gas supply constraint in downstate New York.”
