you must supply user when create department. can access current user request.user if in view
user = request.user or fetch user database if testing in shell
user = user.objects.get(id=1) # then create department:
department = department(name='test', description='test', user=user, ) finally, default=user.pk incorrect. user instance can access user.pk, class attribute user.pk not pk of current user might think is.
