Rails 3 路线：DRY 成员

我需要将以下成员方法添加到许多资源中，有没有办法将其干燥？

 member do
    get   :votes
    post  :up_vote
    post  :down_vote
  end

在我的routes.rb中

resources :news do
  resources :comments do
     member do
        get   :votes
        post  :up_vote
        post  :down_vote
      end
  end
end

resources :downloads do
  resources :whatever do
     member do
        get   :votes
        post  :up_vote
        post  :down_vote
      end
  end
end

EDIT

我实际上已将其移至模块中，如下所示：

module Votable
  module RoutingMethods
    def votable_resources
      member do
        get   "up_votes"
        get   "down_votes"
        post  "up_vote"
        post  "down_vote"
      end
    end
  end # RoutingMethods
end

现在，我的routes.rb 看起来像这样：

require 'votable'

include Votable::RoutingMethods

MyApp::Application.routes.draw do

  namespace :main, :path => "/" do
    resources :users do 
      resources :comments do
        votable_resources
      end
    end
  end

end

请参阅我的内联评论，但我希望命名路线如下所示：main_users_comments_up_votes

你不能在你的路由文件中定义一个方法吗？

def foo
  member do
   get   :votes
   post  :up_vote
   post  :down_vote
  end
end


resources :news do
 resources :comments do
   foo
 end
end

Edit

我以前没有使用过这种技术。当我做“耙路线”时，它似乎起作用了。无论如何，路由文件只是 Ruby 代码。请注意您定义的方法的名称，因为它是在 ActionDispatch::Routing::Mapper 的实例中定义的。

# routes.rb

MyApp::Application.routes.draw do
  puts self
  puts y self.methods.sort
end

# Terminal
> rake routes
