ruby-on-rails - 为多个资源添加公共(public)路由

Question

如何添加 /search一口气连接所有这些资源？

MyCoolApp::Application.routes.draw do

  resources :posts, only [:index, :show, :create] do
    collection { get :search }
  end

  resources :authors, only [:index, :show] do
    collection { get :search }
  end

  resources :comments, only: [:index, :show] do
    collection { get :search }
  end

  resources :categories, only: [:index, :show] do
    collection { get :search }
  end

  resources :tags, only: [:index] do
    collection { get :search }
  end
end

我看到了 this answer这很接近，但我需要能够指定到达资源的操作。有没有更好的方法以更好的方式注入(inject)搜索路线？

%w(one two three four etc).each do |r|
  resources r do
    collection do
      post 'common_action'
    end
  end
end

像这样的东西？

resources :posts, only [:index, :show, :create, :search]

我知道您已标记此问题 ruby-on-rails-3 ，但我将为将来遇到此问题的任何人提供 Rails 4 解决方案。

Rails 4 介绍 Routing Concerns

concern :searchable do
  collection do
    get :search
  end
end

resources :posts, only [:index, :show, :create], concerns: [:searchable]
resources :authors, only [:index, :show], concerns: [:searchable]
resources :comments, only: [:index, :show], concerns: [:searchable]
resources :categories, only: [:index, :show], concerns: [:searchable]
resources :tags, only: [:index], concerns: [:searchable]
