This?

Yup

It didnt work🤔

this is what you can do for this kind of issue. first, dont store your answer inside your question, you did a great job giving verbose name for your model already, so why inconsistent? so the end result should looks like: class Question(models.Model): test = models.ForeignKey(Test, models.CASCADE, null=True) question_text = models.TextField() and then by doing that, you can use your Answer model like this class Answer(models.Model): question = models.ForeignKey(Question, models.CASCADE, related_name='answers') answer_text = models.CharField(max_length=10) is_correct_answer = models.NullBooleanField(default=None) class Meta: unique_together = ('question', 'is_correct_answer',)

But then again, there are supposed to be four choices related to a question, one True, three False. I've observed that it is only allowing me to give one choice as True and another as False if I try for the remaining two to be set to false, gives me an error. What more can I do?

dont set any answer to False, so you can use the database level checks for unique fields, use None value as replacement of False Answer instead

I also noticed setting the values to NULL work. Thanks a lot 👏🏾
