Django iterate through model subclasses

Question

I have following django models:

SALAMI_TYPES = (
    ('S', 'Spicy'),
    ('R', 'Regular')
)
CHEESES = (
    ('P', 'Parmesan'),
    ('C', 'Cheddar')
)
class Pizza(models.Model):
    size = models.IntegerField()
    class Meta:
        abstract = True

class Pepperoni(Pizza):
    salami = models.CharField(max_length=1, choices=SALAMI_TYPES)

class ExtraCheese(Pizza):
    cheese = models.CharField(max_length=1, choices=CHEESES)

And following questions:

How to iterate thought different types of pizzas? For example in menu template.
Where to store forms for each pizza type and how to connect them to a model.

Thanks.

Your question has to be more concrete. You can find answers for your questions just by going trough Django tutorial. — pythad, Nov 15 '15 at 16:35

You can do this by interrogating the python class hierarchy:

How can I find all subclasses of a class given its name?

In your case you would want to get all subclasses of 'Pizza', something like this:

Pizza.__subclasses__()
