title: Rendering a partial from Draper Decorator
body: <p>I have a decorator that returns either a string, or a collection.</p>
  
  <p>In my view, I want to display the return of this decorator method.</p>
  
  <pre><code>class MyDecorator &lt; Draper::Decorator
    def stuff
      if condition
        'some string'
      else
        render model.some_collection
      end
    end
  end
  </code></pre>
  
  <p>Now in my view I want to render the string if it's a string, or render the collection.</p>
  
  <pre><code>= my_object.stuff
  </code></pre>
  
  <p>Unfortunately I cannot access the <code>render</code> method inside <code>Draper::Decorator</code>. Thoughts?</p>
