This is a very simple file to show how to add 'act_as_whatever' to ActiveRecord.

To use it, put the code into a file like lib/your_super_name/acts/idiot.rb and voilà.
Thanks to technoweenie for "acts_as_paranoid" which I used with "acts_as_tree" to build this template.

module YourSuperName
  module Acts
    module Idiot
      # this is called when the module is included into the 'base' module
      def self.included(base)
        # add all methods from the module "AddActsAsMethod" to the 'base' module
        base.extend AddActsAsMethod
      end
      module AddActsAsMethod
        def acts_as_idiot
          # BELONGS_TO HAS_MANY GOES HERE

          class_eval <<-END
            include YourSuperName::Acts::Idiot::InstanceMethods
          END
        end
      end
      
      
      module InstanceMethods
        def self.included(aClass)
          aClass.extend ClassMethods
        end

        # PUT YOUR INSTANCE METHODS HERE
        def idiot(msg)
          "#{self}: I am an idiotic object. And I say '#{msg}'."
        end
        
        module ClassMethods
          # PUT YOUR CLASS METHODS HERE
          def idiot(msg)
          "#{self}: I am an idiotic class. And I say '#{msg}'."
          end
        end
      end
    end
  end
end

ActiveRecord::Base.send :include, YourSuperName::Acts::Idiot
