Upgrading from Django 1.0 to 1.2, I'm suddenly getting errors when
creating objects in the admin form a class that essentially looks like
this:

class MyObject(models.Model):
 name = models.CharField(max_length=50)
 other_thing = models.ForeignKey(MyOtherModel, null=False,
blank=True)

 def save(self, *args, **kwargs):
   logging.debug('saving here')
   if not self.other_thing:
     other_thing = MyOtherModel()
     other_thing.save()
     self.other_thing = other_thing
  super(MyObject, self).save(*args, **kwargs)

Creating a MyObject in the admin and leaving the other_thing field
blank results in the following error:

Cannot assign None: "MyObject.other_thing" does not allow null values.

There is a ticket open on this: http://code.djangoproject.com/ticket/13776
