ruby - Overriding Render in Rails 3 - Request for design review / code refactor -

i'm looking extensible way inject functionality controller.

module social     module request         def self.included( base )             base.alias_method_chain :render, :social             base.alias_method_chain :process_action, :social         end          def process_action_with_social(method_name, *args)             @action = method_name             process_action_without_social(method_name, *args)         end          def render_with_social(action = nil, options = {}, &blk)             if @action == "new"                           # social             end             render_without_social         end     end end  class requestcontroller < applicationcontroller     include social::request      def new              @request = recommendationrequest.new     end end 

this code above working, i'm pretty sure it's not optimal ruby. i'm going creating different modules each controller, bunch of them, actually. code unique each controller, render_with_social.

so questions are:

1. is there way pull other 2 methods out, can not repeat myself? (sorry, first time i've used modules in ruby).
2. is there way without having put include social::request in requestcontroller @ all? (i want able remove these modules, , have controller continue work if nothing had happened)
3. if wind having different suites of these metrics::request, scoring::request etc, best way approach having single location specify modules mixed in controllers?

thanks all.
