title: Django - last insert id
body: <p>I can't get the last insert id like I usually do and I'm not sure why.</p>
  
  <p>In my view:</p>
  
  <pre><code>comment = Comments( ...)
  comment.save()
  comment.id #returns None
  </code></pre>
  
  <p>In my Model:</p>
  
  <pre><code>class Comments(models.Model):
      id = models.IntegerField(primary_key=True)
  </code></pre>
  
  <p>Has anyone run into this problem before?  Usually after I call the save() method, I have access to the id via comment.id, but this time it's not working.</p>
