title: The difference between delete and the other routes
body: <p>Below I have the link-helpers for the actions edit and destroy. The first link (and all the others) is working perfectly but the second creates a weird url that doesn't work.</p>
  
  <pre><code>&lt;%= link_to "Edit", edit_event_path(organizer_vanity_url: event.organizer.vanity_url, id: event.id) %&gt;  
  &lt;%= link_to 'Remove', event_path(organizer_vanity_url: event.organizer.vanity_url, id: event.id), method: :delete, data: { confirm: 'Are you sure?' } %&gt;
  </code></pre>
  
  <p>This is from the routes.rb:  </p>
  
  <pre><code>scope "organizer" do
    scope ":organizer_vanity_url" do
      scope "manage" do
        resources :events
      end
    end
  end
  </code></pre>
  
  <p>What is the difference between the delete link-helper and the others (as that's the only one that doesn't work)?</p>
