I'm trying to write a plugin that will extend InheritedResources.
Specifically I want to rewrite some default helpers.
And I'd like it to "just work" once installed, w/o any changes to application code.
The functionality is provided in a module which needs to be included in a right place. The question is where? :)
The first attempt was to do it in my plugin's init.rb:
InheritedResources::Base.send :include, MyModule
It works in production, but fails miserably in development since InheritedResource::Base declared as unloadable
and so its code is reloaded on each request. So my module is there for the first request,
and then its gone.
InheritedResource::Base is 'pulled' in again by any controller that uses it:
Class SomeController < InheritedResource::Base
But no code is 'pulling in' my extension module since it is not referenced anywhere except init.rb which is not re-loaded on each request
So right now I'm just including the module manually in every controller that needs it which sucks. I can't even include it once in ApplicationController because InheritedResources inherites from it and so it will override any changes back.
