• Rails method as a nested resource

  - by Blastula

  Hello, I'm wondering about the clever way to do this... I have methods that return a value when passed an an object as parameter, such as: <%= average_rainfall(@location) % I'd like to use the exact same methods as a nested resource to call via jQuery/Ajax, like so: .load('/location/8/average_rainfall') I understand how to define the route, but how do I tell my method to 'find' /location/8 and use that as it's parameter instead of @location as expected? Thanks!

• Do autorelease methods always survive a whole method?

  - by Jan Hendrix

  Hi, If I'm correct then the releasing of the pool of autoreleased objects has something to do with the run loop.. I barely have an idea of what that 'run loop' is but my question is, is it possible that the object gets released before the end of the method is reached?

  - by Matt S.

  It's either because of the fact I'm tired or because I'm doing it wrong, but for some reason I can't get it to call a method.

I'm calling it like this: [highscore newHighScore:score]; highscore is what I called the HighScore class in the .h, and score is an int with the score.

• asp.net mvc 2 method not found

  - by Debra

  When I run my asp.net mvc 2 site (shared hosting) I get the following error: Method not found: 'Void System.Web.Mvc.DataAnnotationsModelValidatorProvider.set_AddImplicitRequiredAttributeForValueTypes(Boolean)'. In the bin directory I have System.Web.Mvc.dll version 2.0.50217.0 On my local dev machine it runs fine. Is it possible that if the hosting provider has a different mvc 2 version installed it would cause this error? Thank you!
