Django ORM | What is the best way to create a quiz model?

Question

Django

There is a quiz that branches off depending on the user's answers. This means that if the user has conditionally selected option A, then the options that follow option B will not be selected (i.e., their data will not be filled in).

Now I have implemented all fields in one model with blank and null flags set to True. But it seems to me that this is a bad decision, because. everything comes together in a heap.

Answer 1

Question, Answer Model, and M2M A field next to a question that says which answers the question can follow. Plus the "initial question" flag.
