Question

假设我有一个events控制器。如果我/events请求GET，它将在新闻控制器中以index操作回复，此视图将显示未来事件。

我想添加一个名为past的新操作，它类似于index，它会返回一个Event的数组，但会有另一个查询。

我已将routes.rb添加到此块：

resources :events do
  collection do
    get :past
  end
end

我想知道events_controller：

def history
  @events => Event.past
  render :template => 'index'
end

但是当我在浏览器中请求http://127.0.0.1:3000/events/past它不起作用时，会在日志中抛出这些行：

Started GET "/events/past" for 127.0.0.1 at 2012-04-02 19:32:01 -0500
  Processing by EventsController#show as HTML
  Parameters: {"id"=>"past"}

最后，你有rake routes输出：

            events GET    /events(.:format)                  {:action=>"index", :controller=>"events"}
             event GET    /events/:id(.:format)              {:action=>"show", :controller=>"events"}
       past_events GET    /events/past(.:format)             {:action=>"past", :controller=>"events"}
  contact_us_event POST   /events/:id/contact_us(.:format)   {:action=>"contact_us", :controller=>"events"}
                   GET    /events(.:format)                  {:action=>"index", :controller=>"events"}
                   POST   /events(.:format)                  {:action=>"create", :controller=>"events"}
         new_event GET    /events/new(.:format)              {:action=>"new", :controller=>"events"}
        edit_event GET    /events/:id/edit(.:format)         {:action=>"edit", :controller=>"events"}
                   GET    /events/:id(.:format)              {:action=>"show", :controller=>"events"}
                   PUT    /events/:id(.:format)              {:action=>"update", :controller=>"events"}
                   DELETE /events/:id(.:format)              {:action=>"destroy", :controller=>"events"}

其他测试是使用Rails控制台检查路线：

$ script/rails c
1.9.2-p318 :001 > rs = ActionController::Routing::Routes
1.9.2-p318 :002 > rs.recognize_path "/events/past", :method => :get
 => {:action=>"show", :controller=>"events", :id=>"past"}

怎么了？

Answer 1

尝试：

resources :events do
  get :past, :to => "events#past"
end

我认为您不需要收集上下文。（你可能不需要：分开）

另一种方法是将事件调用放在资源之上。假设你不需要带它的集合。

get 'events/past', :to => "events#past"
resources :events

应该为您提供正确的路线。

Answer 2

问题在于路由优先级，这里有一个routes.rb块可用：

resources :events, :only => [:index, :show] do
  get 'past', :on => :collection
  post 'contact_us', :on => :member
end
