Question

When I just had resources :feedback in my routes.rb, I would use this link helper that would work fine:

<%= link_to 'Delete', feedback, :confirm => 'Are you sure?', :method => :destroy %>

But now, given that I have updated the route to be:

scope ":username" do
  resources :feedbacks
end

I get this error:

ActionView::Template::Error (No route matches {:action=>"show", :controller=>"feedbacks", :username=>#<Feedback id: 1, poster_id: 1, receiver_id: 2, content: "Test 2 is awesome", created_at: "2011-09-10 23:00:32", updated_at: "2011-09-10 23:00:32">}):

How do I create a link to Delete/Destroy using the Rails helper method to this nested resource?

Thanks.

You can always run rake routes to see what the routing system generated, in your case:

feedbacks GET    /:username/feedbacks(.:format) {:action=>"index", :controller=>"feedbacks"}
feedback DELETE /:username/feedbacks/:id(.:format) ....

<< there was wrong code snippet

UPD

So you helper somthing is:

feedback_url('username', feedback.id)

and link_to

= link_to 'Delete', feedback_url(user.name, feedback.id), :method => :delete
