title: How can I make my model fields optional in Django?
body: <p>I'm trying to follow the full example at the bottom of</p>
  
  <p><a href="https://docs.djangoproject.com/en/dev/topics/auth/customizing/">https://docs.djangoproject.com/en/dev/topics/auth/customizing/</a></p>
  
  <p>In my model I have modified to the following</p>
  
  <pre><code>date_of_birth = models.DateField(null=True)
  </code></pre>
  
  <p>However when I try register a user I still get the following error message:</p>
  
  <pre><code>date_of_birth &lt;ul class="errorlist"&gt;&lt;li&gt;This field is required.&lt;/li&gt;&lt;/ul&gt;
  </code></pre>
  
  <p>In what other places do I need to make date_of_birth optional?</p>
