title: Dynamic index path helper
body: <p>I have to path helpers: <em>automobile_albums_path</em> and <em>community_albums_path</em>
  Album model belongs to polymorphic <em>owner</em> and I want to put link to other albums of current album's owner using @album model. </p>
  
  <p>So I want to write something like that: </p>
  
  <pre><code>link_to @album.owner.albums
  </code></pre>
  
  <p>But this does not works. I want to avoid using <em>case</em> statement to select proper helper. Is there a universal one?</p>
