Does custom class interrupt applications in django?

Question

Let's say that I correctly subclassed the User (CustomUser) model (as described here: http://scottbarnham.com/blog/2008/08/21/extending-the-django-user-model-with-inheritance/ )

and installed the comment application.

to access the user comment in the template I am writing:

{{comment.user}} # which provides User, not my CustomUser

and therefore

{{comment.user.CustomProperty}} #does not work.

How can I get around this?

Answer 1

ForeignKey comments.Comment User django, comment.user (.. User). django :

{{ comment.user.customeruser }}

:

{{ comment.user.customeruser.customproperty }}
