title: Rails, Restful Routes, and Awesome Nested Set
body: <p>I have a data structure that is basically a tree using :wesome nested set:</p>
  
  <pre><code>class category
    acts_as_nested_set
  </code></pre>
  
  <p>What I want to achieve are routes like </p>
  
  <pre><code>/categories/1/children/
  /categories/1/children/new
  </code></pre>
  
  <p>I know I could fake it by making a separate controller, but it seems a bit non-DRY. Are there any better ways to do this?</p>
