title: deep nested routes in rails
body: <p>I have an application where the end goal is to have: a user has lists, a list has items, and a item has attachments. Obviously, I would not think about quad nested lists. Would it be any easier if I did something like this:</p>
  
  <pre><code>resources :users do
    resources :lists 
  end
  </code></pre>
  
  <p>and then</p>
  
  <pre><code>resources :items do
    resources :attachments
  end
  </code></pre>
  
  <p>Could I then create my own routes and links which tie lists to items? Or would I still be facing the same issues when placing links_to's or when creating an attachment would I still need to work through user/id/list/id/item/id?  </p>
