Is it possible to safely reopen models within social_engine

[hraynaud]

This seems like standard ruby stuff but for something reason I'm getting mixed results when I try to "monkey patch" Comment class. What's weird is that it works perfectly fine for the Friending class. Examples:

require 'friending'
class Friending < ActiveRecord::Base
  def follow
    friendor.follow(friendee)
  end
end

The above works without a hitch. However if I try to reopen the Comment model for example:

require 'comment'
class Comment < ActiveRecord::Base
  include SearchResult
end

I get an endless array of errors starting ith undefined method is_votable. I suspect this has something to do with the initialization and the fact that the commentable, votable, etc. stuff is added via the AR extension initializer and is called before deprecated routes but I don't understand why this is affecting me.

class Engine < Rails::Engine
    initializer 'social_engine.ar_extensions', :before=>"action_controller.deprecated_routes" do |app|
      ActiveRecord::Base.extend SocialEngine::Voteable
      ActiveRecord::Base.extend SocialEngine::Commentable
      ActiveRecord::Base.extend SocialEngine::Rateable
      ActiveRecord::Base.extend SocialEngine::Favoriteable
      ActiveRecord::Base.extend SocialEngine::Reputatable
      ActiveRecord::Base.extend SocialEngine::Friendable
      ActiveRecord::Base.extend SocialEngine::Sociable
      ActiveRecord::Base.extend SocialEngine::SocialUser      
    end

Is there something special I need to do to reopen this class given this init logic

Thanks
