I want to generate automatic random numbers in a blank field while saving it in django.

The random numbers must be unique.

Simply, I made a random number by random.randint in python. then as i need uniqe number, so i query this number to database, if this number is already exist, then i make again random by while loop.

random_num =  random.randint(2345678909800, 9923456789000)

uniqe_confirm = Order.objects.filter(order_id=random_num)

while uniqe_confirm:
    random_num =  random.randint(2345678909800, 9923456789000)
    if not Order.objects.filter(order_id=random_num):
        break
