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
