How to display random entries in a certain amount in django using the random module?

Question

Django

class ProductView(ListView):
  model = Products
  queryset = Products.objects.filter(draft = False)
  template_name = "products/index.html"

how to change this view so that four random records from the model are displayed using the random module

Answer 1

something like this:

max_id = Products.objects.filter(draft=False).aggregate(max_id=Max("id"))['max_id']
random_products = []

if Products.objects.filter(draft=False).count() < 4:
    raise Exception('Мало объектов для выборки')

while len(random_products) < 4:
    pk = random.randint(1, max_id)
    if pk in random_products:
          continue
    product = Products.objects.filter(draft=False, pk=pk).first()
    if product:
          random_products.append(product)
