• Using the pluralize method in a rake task

  - by Scott S.

  I know this seems silly, but I would like to call some of Rails' Text Helpers in a rake task I am setting up. (Thinks like the pluralize and cycle method: http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html) How would you go about making these available in a rake task, or is it not easily possible?

• Designing a web service to be called by another language

  - by CollegeProgrammer

  This will sound naive (but then I am a junior programmer), but if I write a web service say in Python (standard WSDL web service), I then need to host it so it is reachable from an end point. This will give a URI for the service and then from another language, say Java or VB.NET (any), I can add a web service (this one) and then call the web service's object model, correct? Thanks

  - by ajwaka

  Trying to use SubSonic 3.0.0.4's Linq TEmplates. Got everything working. But in the Doc's I'm seeing how I can use aa IRepository to bulk insert, update, delete my db. Thing is - It wasn't included in the download. Is it somewhere else and I simply overlooked it? I've got a ton of updates going from one "Save" call - so this would be very helpful! Thanks

• DRY way of calling a method in every rails model

  - by Tim

  Along the same lines as this question, I want to call acts_as_reportable inside every model so I can do one-off manual reports in the console in my dev environment (with a dump of the production data). What's the best way to do this? Putting acts_as_reportable if ENV['RAILS_ENV'] == "development" in every model is getting tedious and isn't very DRY at all. Everyone says monkey patching is the devil, but a mixin seems overkill. Thanks!

• WPF Binding to IDictionary<int,MyType>.Values Doesn't Respond to Property Changes?

  - by Phil Sandler

  I am binding a ListView a property that essentially wraps the Values collection (ICollection) on a generic dictionary. When the values in the dictionary change, I call OnNotifyPropertyChanged(property). I don't see the updates on the screen, with no binding errors. When I change the property getter to return the Linq extension dictionary.Values.ToList(), without changing the signature of the property (ICollection) it works with no problem. Any reason why the Values collection bind and notify properly without projecting to an IList<?
