title: Rendering partial from another folder from another partial in Rails 3
body: <p>For example:
  I'm have two models: <code>Task</code> and <code>List</code>. <code>Task</code> <code>belongs_to</code> <code>List</code>.
  I'm render <code>lists/_form.html.erb</code> partial within <code>lists/show.html.erb view</code>.
  Now I need to render <code>tasks/_fields.html.erb</code> partial within <code>lists/_form.html.erb</code> partial:</p>
  
  <pre><code>&lt;%= render 'tasks/fields' %&gt;
  </code></pre>
  
  <p>But I get an error <code>ActionView::MissingTemplate</code></p>
  
  <p>If I try to render <code>tasks/_fields.html.erb</code> within <code>lists/_form.html.erb</code>, everything works.</p>
  
  <p>I see two bad ways to solve this problem:</p>
  
  <ul>
  <li>Place <code>_fields.html.erb</code> to <code>lists</code> folder</li>
  <li>Make a view from <code>lists/_form.html.erb</code> partial and try a "Nested Layouts" from <a href="http://guides.rubyonrails.org/layouts_and_rendering.html" rel="noreferrer">http://guides.rubyonrails.org/layouts_and_rendering.html</a></li>
  </ul>
  
  <p>Is there a good way?</p>
