title: Laravel Eloquent Model::find doesn't work
body: <p>This don't work:</p>
  
  <pre><code>$object = Model::find($id);
  </code></pre>
  
  <p>This works:</p>
  
  <pre><code>$object = Model::where('id', '=', $id)-&gt;first();
  </code></pre>
  
  <p>It doesn't make sense. Am I missing something?
  I'm using Laravel 5.2.36.</p>
