title: Where NOT in pivot table
body: <p>In Laravel we can setup relationships like so:</p>
  
  <pre><code>class User {
      public function items()
      {
          return $this-&gt;belongsToMany('Item');
      }
  }
  </code></pre>
  
  <p>Allowing us to to get all items in a pivot table for a user:</p>
  
  <pre><code>Auth::user()-&gt;items();
  </code></pre>
  
  <p>However what if I want to get the opposite of that.  And get all items the user DOES NOT have yet.  So NOT in the pivot table.</p>
  
  <p>Is there a simple way to do this?</p>
