Brain dump ... Using singletons, forwardable, delegation. - Commented out code - the non ruby way. After several months of objective c development you tend to forget the elegance of Ruby. but thankfully I found my way back.

require 'forwardable'

module Rulers
  module Model
		module HttpModel

			def find(url)
				"HttpModel -> #{self.class.ancestors}"

			def self.included(base)
				base.send(:include, HTTParty)
				base.send(:extend, ClassMethods)
			end

			module ClassMethods
				def find(url)
					"#{self.ancestors}"
				end
			end
			# this is the one that includes HTTParty
		end

		module FileModel

			def find(id)
				begin
					puts "FileModel -> #{self.class.ancestors}"
					new("db/quotes/#{id}.json")
				rescue
					return nil
				end
			end

			def scream!
				"yeah right!!!"
			end

			def self.included(base)
				base.send(:include, InstanceMethods)	
				base.send(:extend, ClassMethods)
			end
			
			module InstanceMethods
				def [](name)
					@hash[name.to_s]
				end

				def []=(name, value)
					@hash[name.to_s] = value
				end

				def find(id)
					begin
						puts "----"

						return nil
