get_or_create() and create() with unspecified non-nullable fields

Using Django Using the ORM

Long-overdue update: I opened #35671 and added a documentation note that empty strings on string-based fields don’t violate null=False.

Also FWIW, to completely disallow empty strings from the database, you can use a CheckConstraint like the following in your model’s Meta class.

from django.db.models import Q, CheckConstraint

constraints = [
    CheckConstraint(condition=~Q(field=""), name="field_non_empty"),
    # ...
]
