Hi,
I searched about this subject and found only a few very old posts, so
maybe there is a better solution now.
As you may guess the model I'd like to code is similar to the Pizza -
Toppings you know from the "Creating Models" documentation:
class Topping(models.Model):
# ...
class Pizza(models.Model):
# ...
toppings = models.ManyToManyField(Topping)
And what if I need to say that I can have two or three times the same
topping on my pizza? Something like twice mozzarella cheese and 3
times green olives topping?
I though about an intermediary class and indeed this is the same
solution found in those old posts mentioned before:
class Topping(models.Model):
# ...
class ToppingAndQuantity(models.Model):
amount = models.IntegerField()
topping = models.ForeignKey(Topping)
class Pizza(models.Model):
# ...
toppings = models.ManyToManyField(ToppingAndQuantity)
I think it's ugly.
Can you suggest me a better solution?
It's that intermediary class really needed?
Thank you,
Giovanni.
