Hello,
I have a question that is best illustrated by the following fictional
example. (I put my question at the end.)
#=========
# In models.py
class Room(models.Model):
animal = models.ForeignKey(Animal)
class Animal(models.Model):
#[...]
class Duck(Animal):
#[...]
# In views.py
my_duck = Duck()
#[...]
my_room = Room(animal=my_duck)
#[...]
# QUESTION: What should the following expression return?
isinstance(my_room.animal, Duck)
#=========
Django appears to return False. Accordingly, I get an error when I try
to call the quack() method on my_room.animal, since that method is
defined for Ducks but not for Animals. I am running into a situation
where I would like to call the quack() method if the room's animal is
an instance of Duck. Is there some way to do this?
Regards,
Rex
