Python django 'QueryDict' object 没有属性 'subject'

Question

how do I write here because I do not know how to solve my problem, it turns out that I am creating an online test portal and I need to know that I am failing, I explain the context at the time of creating a question an evaluation index should be indicated, and this has a filter that agrees the subject and course of the test in question. Well the filter works shows me the indicators that are of a specific course and subject, but only when I enter a manual id instead when I pass the quiz variables it throws the error: 'QueryDict' object has no attribute 'subject 'I leave the form code and the view so they can tell me that I am failing please.

forms.py

class QuestionForm(forms.ModelForm):

class Meta:
    model = Question
    context_object_name = 'questions'  
    fields = ('number','planificacion','text','description', 'puntaje' ,'image','document' )
    label = 'Pregunta'



def __init__(self ,quiz ,*args, **kwargs):
    super().__init__(*args, **kwargs)
    self.fields['planificacion'].queryset = PlanificacionIndicador.objects.filter(planificacion__asignatura__id=quiz.subject.id, planificacion__curso__id=1)

As you can see in the filter I did the planning__course__id = 1 has an id set manually and the other has as I want, I must say that the filter works what fails is that at the time of wanting to save throws the error.

view.py

@login_required
@teacher_required
def question_add(request, pk):

quiz = get_object_or_404(Quiz, pk=pk, owner=request.user)

if request.method == 'POST':
    form = QuestionForm(request.POST, request.FILES)


    if form.is_valid():
        question = form.save(commit=False)
        question.quiz = quiz
        question.save()
        messages.success(request, 'Ahora puede agregar respuestas / opciones a la pregunta.')
        return redirect('teachers:question_change', quiz.pk, question.pk)
else:
    form = QuestionForm(quiz=quiz)
return render(request, 'classroom/teachers/question_add_form.html', {'quiz': quiz,'form': form})

this is the error

Answer 1

You forgot to put in the quiz arg to QuestionForm.__init__ in the POST case. That line should read

    form = QuestionForm(quiz, request.POST, request.FILES)
