title: How to decorate nested attributes (associations) with Draper in Rails 3?
body: <p>My environment:</p>
  
  <ul>
  <li>Rails 3.2
  
  <ul>
  <li>with <a href="https://github.com/jcasimir/draper" rel="noreferrer">draper</a> gem</li>
  </ul></li>
  </ul>
  
  <p>I'm using nested resources and having trouble figuring out where to declare the decorator.</p>
  
  <pre><code>#app/controllers/users_controller.rb
  def show
    @user = UserDecorator.find(params[:id])
    @items = @user.items
  end
  
  #app/controllers/items_controller.rb
  def show
    @item = @user.items.find(params[:id])
  end
  </code></pre>
  
  <p>I tried replacing <code>items</code> with <code>ItemDecorator</code> and it didn't work. Where should I be putting it?</p>
  
  <p>I know that Draper has issues with nested resources in forms, but this isn't a form!</p>
