title: Laravel morph belongs to?
body: <p>I've got a situation where multiple tables have a <code>belongsTo</code> relationship to a category table in <code>laravel 5.4</code>.</p>
  
  <p>So I thought about this structure:</p>
  
  <p><strong>User</strong> table:</p>
  
  <pre><code>id
  name
  email
  category_id   &lt;--
  </code></pre>
  
  <p><strong>Category table</strong></p>
  
  <pre><code>id
  model_type
  name
  </code></pre>
  
  <p>Is this possible with a <code>morph</code> relationship?</p>
