title: Django/postgresql: DETAIL: Failing row contains (43, , 1, 2016-01-02, 31, null, null)
body: <p><strong><em>I am attempting to submit a comment like so...</em></strong></p>
  
  <pre><code>Comment.objects.create(content = comment, post = post, user = request.user)
  </code></pre>
  
  <p><strong><em>When I do this I am getting the following error...</em></strong></p>
  
  <pre><code>IntegrityError at /addcomment/1
  null value in column "commentnumber" violates not-null constraint
  DETAIL:  Failing row contains (43, , 1, 2016-01-02, 31, null, null).
  </code></pre>
  
  <p>The two 'nulls' that are failing non null constraints are previous fields named<code>commentnumber</code> and <code>commentcount</code> in the <code>Comment</code> model that I later deleted by deleting the migrations file and then using <code>makemigrations</code> and <code>migrate</code> to save the changes. </p>
  
  <p>Why am I still required to enter information into to <code>commentnumber</code> and <code>commentcount</code> when they are clearly deleted?</p>
  
  <p>If any more information is needed, please ask in the comments. I would be happy to oblige. </p>
