Re: Best practices to create multiple users profiles using Auth

I actually just wrote a blog post about why I think extending
contrib.auth.models.User is a better solution to using a OneToOneField
(or a ForeignKey), you can find it here:

http://ryanwest.info/blog/2011/django-tip-5-extending-contrib-auth-models-user/

Please let me know what you think.

Regards,

Ryan
