Dear Django Users,
I have been running into a problem with the app I am developing and I
haven't been able to find a good solution. Suppose I have the following
model:
class MyModel(models.Model):
a = models.CharField(max_length=255, null=True, blank=True)
b = models.ForeignKey('MyOtherModel', null=True, blank=True,
on_delete=models.SET_NULL)
# some more model fields
The task I am trying to accomplish is the following: If an instance of
"MyOtherModel" is deleted, a and b of the related MyModel-instance
should be set to NULL in the database, but the instance of MyModel with
the other fields should remain. The model above only sets b to NULL but
not a.
Any ideas?
Regards,
Jann
