SET() [source]
Set the ForeignKey to the value passed to SET(), or if a callable is passed in, the result of calling it. In most cases, passing a callable will be necessary to avoid executing queries at the time your models.py is imported:
from django.conf import settings
from django.contrib.auth import get_user_model
from django.db import models
def get_sentinel_user():
return get_user_model().objects.get_or_create(username='deleted')[0]
class MyModel(models.Model):
user = models.ForeignKey(
settings.AUTH_USER_MODEL,
on_delete=models.SET(get_sentinel_user),
)
