title: Django values_list vs values
body: <p>In Django, what's the difference between the following two:</p>
  <pre><code>Article.objects.values_list('comment_id', flat=True).distinct()
  </code></pre>
  <p>VS</p>
  <pre><code>Article.objects.values('comment_id').distinct()
  </code></pre>
  <p>My goal is to get a list of unique comment ids under each <code>Article</code>. I've read the documentation (and in fact have used both approaches). The results overtly seem similar.</p>
