Question

由于我不知道如何解决问题，我该怎么写，事实证明我正在创建在线测试门户，我需要知道我失败了，我在创建主题时解释了上下文如果有问题，则应指出评估指标，并且该指标具有一个过滤器，以使所讨论的测试的主题和过程一致。好了，过滤器的工作原理向我展示了特定课程和主题的指标，但是只有当我输入手册ID而不是通过测验变量时，它才会引发错误：'QueryDict'对象没有属性'subject'我离开了表单代码和视图，以便他们可以告诉我我失败了。

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)

正如您在过滤器中看到的那样，我确实在Planning__course__id = 1上手动设置了一个ID，而另一个我想要的，我必须说该过滤器有效，是因为要保存时抛出了错误

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})

这是错误

Answer 1

在quiz情况下，您忘记将QuestionForm.__init__ arg放入POST。该行应显示为

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

Python Django'QueryDict'对象没有属性'subject'
