Rails: simple resource routes generation (rails 3.0)

gistfile1.rb

module ActionDispatch

      # resources can be one or more resource types (should be plural)
      #
      # ex: simple_resources :widgets
      #
      # This will generate the following routes:
      #
      # GET widgets => widgets#index
      # GET widget/:id => widgets#show
      # PUT widget/:id => widgets#update
      # DELETE widget/:id => widgets#destroy
      # POST widget => widgets#create
      def simple_resources(*resources)
        resources.each do |resource|
          multi_resource = resource.to_s
          single_resource = multi_resource.singularize
          controller = multi_resource
          get multi_resource, :to => "#{controller}#index"
          get "#{single_resource}/:id", :to => "#{controller}#show"
          put "#{single_resource}/:id", :to => "#{controller}#update"
          delete "#{single_resource}/:id", :to => "#{controller}#destroy"
          post "#{single_resource}", :to => "#{controller}#create"
        end
        self
      end

      # another version, assumes resource is singular
      # ex: simple_resource :widget
      def simple_resource(*resource, &blk)
        default_params = [*resource]
        resources(*default_params, &blk)
        domain = resource[0].to_s.singularize
        get "/#{domain.pluralize}", :to => "#{domain}#index"
        self
      end
