Looks like you have an indentation problem in clean_username - the lines
under the first "raise forms.ValidationError" should be one level to the
left, otherwise they will never be reached and the method will never return
the cleaned value for username.

IntegrityError at /register/ auth_user.username may not be NULL
I'm getting the following error with my registration section of my
program.
IntegrityError at /register/
auth_user.username may not be NULL
I am using django 1.3.1 and python 2.7.2 and I'm using sqlite3 as the
database.
I am a newbie and I'm learning Djanogo from the book "Learning website
development with Django"
The registration form is displayed ok and I'm able to fill it out and
it is when I click register that the problem occurs.
