Question

I am trying to insert those value I got from radio buttons after the user as taken options. Then I want to insert it into another table which I will use to prepare the final result for the student. After I've taken all my values and created an insert query, I am getting this error.
models.py:
class Question(models.Model):
course = models.ForeignKey(Course, on_delete=models.CASCADE, related_name='questions')
text = models.CharField('Question', max_length=500)
def __str__(self):

class Answer(models.Model):
question = models.ForeignKey(Question, on_delete=models.CASCADE, related_name='answers')
text = models.CharField('Answer', max_length=255)
is_correct = models.BooleanField('Correct answer', default=False)
def __str__(self):
return self.text
class TakenQuiz(models.Model):
student = models.ForeignKey(Student, on_delete=models.CASCADE, related_name='taken_quizzes')
course = models.ForeignKey(Course, on_delete=models.CASCADE, related_name='taken_course')

selected_choice = models.ForeignKey(Answer, on_delete=models.CASCADE, null=True)
marks_obtained = models.DecimalField('Marks Obtained', default=0, decimal_places=2, max_digits=6)
is_correct = models.BooleanField('Was this attempt correct?', default=False, null=False)
date = models.DateTimeField(auto_now_add=True)

Answer 1

question_pk = request.POST.getlist('question_pk')
question_obj = Question.objects.filter(id=int(question_pk)
while save
takenquiz.question = question_obj
