title: How can I show auto_now_add field in Django admin?
body: <p>I have a model (as below) and in that, I've set <a href="https://docs.djangoproject.com/en/3.0/ref/models/fields/#django.db.models.DateField.auto_now_add" rel="nofollow noreferrer"><strong><code>auto_now_add=True</code></strong></a> for the <code>DateTimeField</code>  </p>
  
  <pre><code>class Foo(models.Model):
      timestamp = models.DateTimeField(auto_now_add=True)</code></pre>
  
  <p>From the doc,</p>
  
  <blockquote>
    <p>As currently implemented, setting <code>auto_now</code> or <code>auto_now_add</code> to <code>True</code> will cause the field to have <code>editable=False</code> and <code>blank=True</code> set.</p>

  <p>Q: How Can I show this <strong><code>auto_now_add</code></strong> field in Django Admin? (by default Django Admin doesn't show <code>auto_now_add</code> fields)</p>
