动态视图不显示

Question

我想要参加测验，如果您回答错误的问题，您会看到该问题会被添加到错误问题列表中。

问题，可以在多个测验中使用，所以我不能硬编码问question_1然后question_2等

当我打开我看到的第一个问题，但这时如果我提交或刷新我看到右边的页面。 html模板。它没有提出所有的问题。

应该要求所有的问题渲染right.html页面之前

for question in quiz.questions.all(): 
    if question not in asked_questions: 
     asked_questions.append(question) 
     return answer_question(request, quiz_id, question.id, module_list) 

models.py

class Choice(models.Model): 
    choice = models.CharField(max_length=64) 
    def __unicode__(self): 
     return self.choice 

#create a multiple choice quiz to start 
class Question(models.Model): 
    question = models.CharField(max_length=64) 
    answer = models.CharField(max_length=64) 
    choices = models.ManyToManyField(Choice) 
    module = models.CharField(max_length=64) 

    def __unicode__(self): 
     return self.question 

class Quiz(models.Model): 
    name = models.CharField(max_length=64) 
    questions = models.ManyToManyField(Question) 

    def __unicode__(self): 
     return self.name 

views.py

asked_questions = [] 
module_list = [] 
module_list.append('test') 

def take_quiz(request, quiz_id): 
    quiz = Quiz.objects.get(id=str(quiz_id)) 

    for question in quiz.questions.all(): 
     if question not in asked_questions: 
      asked_questions.append(question) 
      return answer_question(request, quiz_id, question.id, module_list) 
    #quiz is over 
    return render (request, 'right.html') 

def answer_question(request, quiz_id, question_id, module_list): 
    question = Question.objects.get(id=question_id) 
    #module_list = [] 
    if request.method == 'POST': 
     form = QuestionForm(request.POST) 
     choices = [(i, i) for i in question.choices.all()] 
     form.fields['selection'].choices = choices 

     if form.is_valid(): 
      if form.cleaned_data['selection'] != str(question.answer): 
       module_list.append(question.module) 
      return take_quiz(request, quiz_id) 
    else: 
     form = QuestionForm() 
     choices = [(i, i) for i in question.choices.all()] 
     form.fields['selection'].choices = choices 

    return render(request, 'answer_question.html', {'question':question, 'form':form, 'module_list':module_list}) 

Answer 1

如果您计划托管这并在网上提供，你应该重新开始。您不应该使用这样的列表来存储内容，您应该使用sessions或cache。此外，您最好使用FormWizard进行测验，因为它旨在完成您想要做的事情：处理多个表单并处理它们。

Answer 2

也许你应该尝试

return HttpResponseRedirect(reverse('answer_question', args=[quiz_id, question_id, module_list])) 

到视图重定向到另一个视图。

P.S .:反转应该包含你的“answer_question”鉴于
