Is it possible to filter by the ManyToMany fields? Suppose I have a Pizza model and a Topping model. Topping has a ManyToManyField pointing to Pizza. I now have an instance of a Pizza called mypizza.
I would like to now search for all Pizzas with the EXACT same Toppings as mypizza. Intuitively it would like something like this: Pizza.objects.filter(toppings=mypizza.toppings_set) This, naturally, does not work. Any ideas? I'm happy to do some fancy black magic with the models to make it work, or do a custom SQL clause. I just don't know enough SQL to do that. I'm also interested in reasonably alternative ways to model my data if I have a potentially very large set of Pizzas however a limited (although fairly lengthy, 20+) list of toppings that might change periodically.
