Update Boolean field and Integer fields from Django view

Question

Can someone please point me in the right direction here. I have a quiz app where I want to implement some user progress objects. I have a QuizResult model which foreignkeys to user, quiz and lesson. What I want is to be able to update a couple of fields: score (integer field) and complete (boolean field) from my views.py function. when I try to update these fields from my frontend I get a no errors, but the object shows complete and score fields as null.

Here is my model:

class QuizResult(models.Model):
    student = models.ForeignKey(User, related_name="results", on_delete=models.CASCADE)
    quiz = models.ForeignKey(Quiz, related_name="results", on_delete=models.CASCADE)
    lesson = models.ForeignKey(Lesson, null=True, blank=True, related_name="results", on_delete=models.CASCADE)
    score = models.IntegerField(blank=True, null=True)
    complete = models.BooleanField(default=False)

and my view.py function:

@api_view(['POST'])
def post_progress(request, pk):
    data = request.data
    score = data.get('score')
    complete = data.get('complete') 

    quiz = Quiz.objects.get(pk=pk)

    user_progress = QuizResult.objects.create(quiz=quiz, score=score, complete=complete, student=request.user)

    serializer = QuizResultSerializer(user_progress, data=data)

    return Response(serializer.data)
