Проблема с Django formview, не удается добавить форму в детальное представление

У меня проблема с установкой классов detail view и form view в django, когда я пытаюсь нажать кнопку send в моей экзаменационной форме django выкидывает эту ошибку: AttributeError: 'TestDetails' object has no attribute 'object'

class TestDetails(DetailView, FormView):
model = Test
form_class = QuestionForm
context_object_name = 'test'
pk_url_kwarg = 'test_id'
template_name = 'app/views/test_details.html'

def get_context_data(self, **kwargs):
    test_id = self.kwargs.get('test_id')
    context = super().get_context_data(**kwargs)
    context['title'] = f'Тест - {test_id}'
    context['questions'] = Question.objects.filter(test_id=test_id)
    return context

def form_valid(self, form):
    print(form.cleaned_data)
    return super().form_valid(form)

def form_invalid(self, form):
    print(form.cleaned_data)
    return super().form_invalid(form)

And this is a full traceback

    Internal Server Error: /tests/1

    if self.object:
AttributeError: 'TestDetails' object has no attribute 'object'

Вообще-то, я не знаю, как решить эту проблему

def get_context_data(self, **kwargs):
   context = super().get_context_data(**kwargs)
   test_id = context['test'].id 
   context['title'] = f'Тест - {test_id}'
   context['questions'] = Question.objects.filter(test_id=test_id)
   return context
