Django Unit Tests Missing Database Columns

问题

I created a unit test on Django to create a user account and send a verification e-mail. The user is created, but the e-mail fails to send. The e-mail's default contents are supposed to be created as a field in the user when a user is created, but for some reason, Django is claiming -

DatabaseError: no such column: app_userprofile.default_email_header

It works fine when the account is created manually, though for some reason it fails to create that column in the database when done from a unit test. Any suggestions for fixing this?

Note: South was used to migrate changes in models.py - could that be the problem?
