title: What will my Delete helper - in Rails 3- look like for a route that's nested?
body: <p>When I just had <code>resources :feedback</code> in my <code>routes.rb</code>, I would use this link helper that would work fine:</p>
  
  <pre><code>&lt;%= link_to 'Delete', feedback, :confirm =&gt; 'Are you sure?', :method =&gt; :destroy %&gt;
  </code></pre>
  
  <p>But now, given that I have updated the route to be:</p>
  
  <pre><code>scope ":username" do
    resources :feedbacks
  end
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>ActionView::Template::Error (No route matches {:action=&gt;"show", :controller=&gt;"feedbacks", :username=&gt;#&lt;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"&gt;}):
  </code></pre>
  
  <p>How do I create a link to <code>Delete/Destroy</code> using the Rails helper method to this nested resource?</p>
  
  <p>Thanks.</p>
