Given...
class Place(models.Model):
name = models.CharField(max_length=50)
class Restaurant(Place):
serves_hot_dogs = models.BooleanField()
...it is trivial to create either a place or restaurant. But how do
you take an instance that is already a place and create a restaurant
from it? Is this possible, without first deleting the place?
I though this would work:
restaurant = Restaurant()
place = Place.objects.get(id=1)
restaurant.place = place
restaurant.save()
But this creates a new restaurant (and a new place) unrelated to the
existing place.
What am I missing? Thanks in advance.
