Python Database Django

[gilesgerman]

I have a list of questions with a list of multiple choice answers.

I am trying to get details of a user who will then answer the questions and store their answers next to their name. The questions/answers may change moving forward.

I have the following code is this correct can you help please?

from django.db import models

class Investor(models.Model):
    Investor = models.CharField(max_length=100, default="")

    def __str__(self):
        return self.Investor

class Question(models.Model):
    Question_text = models.TextField(max_length=200,default="")

    def __str__(self):
        return self.Question_text

class Option(models.Model):
    Question = models.ForeignKey(Question, on_delete=models.CASCADE)
    Option = models.CharField(max_length=50, default="")

    def __str__(self):
        return self.Option

class Answer(models.Model):
    Investor = models.ForeignKey(Investor, on_delete=models.CASCADE, default="")
    Question = models.OneToOneField(
        Question,
        on_delete=models.CASCADE,
        primary_key=True,
    )
    Answer = models.OneToOneField(
        Option,
        on_delete=models.CASCADE,
        primary_key=True,
    )
