Question

Suppose I have an events controller. If I request /events by GET it will respond with index action in news controller, this view will display future events.

I want to add a new action called past, it is like index, which return an array of Events but with another query.

I have added to routes.rb this chunk:

resources :events do
  collection do
    get :past
  end
end

and I this chuck to events_controller:

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

But when I request http://127.0.0.1:3000/events/past in browser it does not work, in log are thrown these lines:

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"}

And finally here you have rake routes output:

            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"}

Other test was check routes using Rails console:

$ 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"} 

What’s wrong?

Answer 1

The problem was on routes precedence, here you have a routes.rb chunk that works:

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