I keep getting the show action instead of a custom action when using a nest route

Question

My setup isn't too complex I think, I have an Event with some RSVPs. My routes file has

map.resources :events, :has_many => :rsvps
map.resources :rsvps, :only => [:new, :create, :destroy, :index], :collection => { :list => :get }
 map.resources :events do |event|
event.resources :rsvps, :only => [:new, :create, :destroy, :index], :collection => { :list => :get }
      end

Which give me a rake routes

                    event_rsvps GET    /events/:event_id/rsvps(.:format)               {:action=>"index", :controller=>"rsvps"}

                            rsvp DELETE /rsvps/:id(.:format)                            {:action=>"destroy", :controller=>"rsvps"}

                                 DELETE /events/:event_id/rsvps/:id(.:format)           {:action=>"destroy", :controller=>"rsvps"}
                                 GET    /events(.:format)                               {:action=>"index", :controller=>"events"}
                                 POST   /events(.:format)                               {:action=>"create", :controller=>"events"}
                                 GET    /events/new(.:format)                           {:action=>"new", :controller=>"events"}
                                 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"}

I then have a

<%= link_to 'List Attending', list_event_rsvps_path(event) %> 

But when I click this view I get

Unknown action

No action responded to show. Actions: create, current_admin, current_admin=, destroy, index, list, new, sign_in, sign_out, and signed_in?

the server log shows

Processing RsvpsController#show (for 127.0.0.1 at 2014-01-10 16:12:18) [GET] Parameters: {"id"=>"list", "event_id"=>"1"}

At this point I've tried everything I could find about the subject. I'm using ruby 1.8.7 and Rail 2.3.18 since my web host is using that still. I have no clue why it's still looking for the show action when I've removed it from the controller and all the routes.

Answer 1

The routes are applied in the order they are defined. Try putting:

map.resources :events, :has_many => :rsvps

Below the other routes.
