class Place(models.Model):

description = models.TextField()
def unicode(self):

return self.description

def reload(self):

self = Place.objects.get(id = self.id)

class Restaurant(Place):

name = models.TextField()

#console
from myapp.models import *
p1 = Place.object.create(description = "description1")
r1 = Restaurant.object.create(id = p1.id, description = p1.description, name =name)
r1.delete()
r1 = Restaurant.objects.get(id = r1.id)
# return expected error
p1 = Place.objects.get(id = p1.id)
# return unexpected error, possible because that row is also deleted
