Having:
_______________
class Pizza(models.Model):
name = models.TextField()
toppings = models.ManyToManyField(Topping)
class Topping(models.Model):
name = models.TextField()
_______________
...and for instance having toppings 'tomato' and 'cheese', how do I
select all pizza's with BOTH toppings? I would say by using a filter
chain, such as:
_______________
Pizza.objects.filter(topping=topping_tomato).filter(topping=topping_cheese)
(where topping_tomato and topping_cheese are topping instances.
_______________
...but although each individual filter returns a result the chain
returns an empty list.
