Allow null in foreign key to user. Django
django, django-admin
Solution
`club_vacancy.user_id may not be NULL`
Looks very much like an error from your database, rather than from Django.
It seems most likely that you added `null=True` after running `manage.py syncdb`. You'll need to modify your database schema to allow null values in that column.
Problem
I have this model ``` class Vacancy(models.Model): user = models.ForeignKey(User, null=True, blank=True, default = None) name = models.CharField(max_length=64) ``` When in admin i try to creat a vacancy without a user. And it throws an error " club_vacancy.user_id may not be NULL". Am i doing something wrong?
