Pass random value from get method to post method Django?

Question

Django

Let's say I have a view that inherits from the View class

class SomeVeiwClass(View):
    def get_random_number(self):
        return random.randint(1, 100)

    def get(self, request):
        context = {
            'some_number': self.get_random_number()
        }
        return render(request, 'some_template.html', context)

    def post(self, request):
         context = {
             'some_number': self.get_random_number()
         }
         return render(request, 'some_template.html', context)

The fact is that in this way I call the function every time, which means I get different numbers, so the question is how to make it so that once the random number received can be used in the post method, I tried to create an instance of the SomeViewClass class (the same class) and give it the result of calling the get_random_number method , but then I get

TypeError: get_random_number() missing 1 required positional argument: 'self'

though I call in the same class. I tried to pass a variable through a hidden input in html, but then it can be changed, and I need to make sure that the user cannot influence it in any way. I know that you can just write the result of calling the get_random_number method through shelve to some file when calling the get method, and then read from the same file when calling the post method, but I doubt the speed of such an operation :(

Answer 1

In the get method, store the random value in the session, and in the post, retrieve it from it.
