To extend the User object with custom fields, the Django docs recommend using UserProfiles. However, according to this answer to a question about this from a year or so back:
extending django.contrib.auth.models.User also works better now -- ever since the refactoring of Django's inheritance code in the models API.
And articles such as this lay out how to extend the User model with custom fields, together with the advantages (retrieving properties directly from the user object, rather than through the .get_profile()).
So I was wondering whether there is any consensus on this issue, or reasons to use one or the other. Or even what the Django team currently think?
I vote for using UserProfiles.
I use several thrid party apps. And a foreign key to a User will always Point to auth.models.User.
Example:
class Article(models.Model):
user = models.ForeignKey('auth.User') # instead of your CustomUser
text = ....
And your custom User model:
class CustomUser(User):
timezone = models.CharField(max_length=50, default='Europe/London')
# Use UserManager to get the create_user method, etc.
objects = UserManager()
What will be happen if you access the user field through an Article instance? This will raise an exception:
u = a_article.user
u.timezone
AttributeError: 'User' object has no attribute 'timezone'
Maybe this isn't a problem for you and you wan't to avoid the additional DB query. But i would use the get_profile way.
UPDATE May, 2013
Since Django 1.5 you can extend the default User model, or substitute with a completely customized model.

The above solution is obsolete, see the comment from wim
