Can anyone tell me the "proper" way to extend a model provided by an app engine (or any plugin for that matter).
I'm attempting to extend an app engine model by adding a has_many :through. So I've got lib/myplugin_ext.rb and I'm requiring that file in evironment.rb. My extension uses class_eval to add the association. This works fine in the console for viewing and adding stuff to the has_many :through association, but in dev mode -- after the first request -- if I try to add to the has_many :through, I get "TypeError: Can't dup NilClass". Because it works in the console but not in development mode after the first request, this leads me to believe that it's a weird problem with the reloader and how I'm extending the class. I've tried virtually everything I can think of (aside from just moving the models from the app engine into my app directory and modifying it there, which works...), but I can't seem to avoid this error any other way. I tried the "unloadable" suggestion posted here: http://strd6.com/?p=250 Adding unloadable to the app engine model only seemed to make the situation worse. The app engine model gets reloaded without the extension at all on subsequent requests. I isolated the problem in a blank app and posted it here on github: http://github.com/brentd/cantdupnilclass/tree/master The stack trace is also available at that repo. If I'm doin' it completely wrong, please tell me what would help. Much appreciated :) Brent --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
