  <p>This is what happened when I ran <code>manage runserver</code>:</p>

  <p>This is what <strong><em>models.py</em></strong> file contains:</p>
  
  <pre><code>from django.db import models
  from django.contrib.auth.models import AbstractUser
  from django.utils.translation import ugettext_lazy as _
  class User(AbstractUser):
      username = models.CharField(max_length=255, unique=True, verbose_name=_("Username")) 
      email = models.EmailField(unique=True, verbose_name=_("Email Address"))
      favorite_animal = models.CharField(max_length=255, verbose_name=_("Favorite Animal"))
  </code></pre>
