title: Column not found: 1054 Unknown column 'taggables.tags_model_id' in 'field list' laravel eloquent
body: <p>I am going to implement a query that retrieves all my blogs with their tags. I am using Laravel Eloquent polymorphic relations but I have an error that is <code>Column not found: 1054 Unknown column 'taggables.tags_model_id' in 'field list'</code>. All my codes in both laravel and my SQL are presented below:</p>

  <p>when I called this query the result is an empty array</p>
  
  <pre><code> public function getItemsWithTags(array $attr)

      }

  <p>thank you very much.</p>
