Overriding ActionController method in an app

i can't seem to get this working... basically, i want to use a patch that was added to rails:

http://dev.rubyonrails.org/changeset/8785

but i don't want to have to upgrade past 2.0.2, and i don't want to have to freeze rails inside the app.

so i was hoping to override the methods in ActionController required to make the patch to my app only. i created a file called 'path_patch.rb' and put it in my config/initializers dir, which contains the following:

ActionController::Resources::Resource.class_eval do   attr_reader :path_segment

  def initialize(entities, options)     @plural ||= entities     @singular ||= options[:singular] || plural.to_s.singularize     @path_segment = options.delete(:as) || @plural

    @options = options

    arrange_actions     add_default_actions     set_prefixes   end

  def path     @path ||= "#{path_prefix}/#{path_segment}"   end

end

but it doesn't work. and, actually, no matter how hard i try (using this or other code) i can't seem to override the path method, even to just cause it return bogus info.

help!

TIA
