Hello,
I’m relatively new to Django. I’ve been working through Django for Professionals by William Vincent and using the Django docs. I’m trying to create a custom user class and use the Django admin site page to add a custom user.
When I go to the admin site and try to add a new user I get the traceback below.
I thought it may be this, but it doesn’t seem to help:
Any suggestions on where to look next greatly appreciated.
Full traceback:
