title: Getting a pivot column in Eloquent query
body: <p>I am trying to retrieve some models and a <code>pivot</code> column in the same query.</p>
  
  <p>I have 3 tables.</p>
  
  <p>materials</p>
  
  <pre><code>id | name
  </code></pre>
  
  <p>items_fabrics</p>
  
  <pre><code>id | name | item_id
  </code></pre>
  
  <p>items_fabrics_materials</p>
  
  <pre><code>id | fabric_id | material_id | percentage
  </code></pre>
  
  <p>Using <code>Item::with('fabrics', 'fabrics.materials')-&gt;find(1);</code> </p>
  
  <p>I can get all the fabrics and materials, but the <code>percentage</code> column is left out. How do I get this with it?</p>
