Is there a way to shorten this process (I know in Delphi and some other codes there are "case" statements for this. But would a case statement be possible in Django/Python -

How to perform a __all_in query with Django?
I have three models class Pizza(models.Model): toppings = models.ManyToManyField(Topping) class Topping(models.Model): name = models.CharField(max_length=50) class Order(models.Model): must_have_toppings = models.ManyToManyField(Topping) I want to find all Orders that match a certain Pizza. For this, I would like to do something like orders = Order.objects.filter(must_have_toppings__all_in=my_pizza.toppings) What I tried: orders = Order.objects.filter(must_have_toppings__in=my_pizza.toppings) doesn't work, because Orders with just one of the Pizza's toppings in their must_have will be returned. And: orders = Orders.objects for topping in my_pizza.toppings.all(): orders = orders.filter(must_have_toppings=topping) doesn't work, because it will return orders that have all the toppings from the pizza, even if some of the must_have_toppings are missing. For example, a Pizza with Tomatoes and Mushrooms will return an Order that needs Tomato, Pepper, and Mushroom. How can I look for Orders where the must_have_toppings are ALL in the Pizza object?

'Tag' object has no attribute 'count' in for loop
I am building a BlogApp and I am trying to create a notification when a particular tag is used 10 times. So i am using if statement in for loop so if any tag used 10 times then create notification But when i try to count then it is showing 'Tag' object has no attribute 'count' models.py class Post(models.Model): post_user = models.ForeignKey(User, on_delete=models.CASCADE) psot_title = models.CharField(max_length=30) class Comment(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) post_of = models.ForeignKey(Post, on_delete=models.CASCADE) views.py def page(request): subquery = Tag.objects.filter(post__post_user=request.user).annotate( num_name=Count('name') for que in subquery: if que.count() > 10: Notification.objects.create(user=request.user) context = {'subquery':subquery} return render(request, 'page.html', context} What have i tried :- I also tried len like :- for que in subquery: if len(que) > 10: Notification.objects.create(user=request.user) But it showed object of type 'Tag' has no len() I have tried many times by removing count() and len() but it showed 'int' object has no attribute 'name' Any help would be much Appreciated.
