我正在尝试使用表单向导，但我不知道在哪里设置字段的选项。

#views.py
class QuizWizard(SessionWizardView):
    def done(self, form_list, **kwargs):
        return render_to_response('done.html', {
            'form_data':[form.cleaned_data for form in form_list],
        })

#forms.py
class QuestionForm(forms.ModelForm):
    #selection = forms.ChoiceField()
    class Meta:
        model = Question

我看到一个空表单，看起来像是添加对象的管理面板。我希望能够将问题传递给表单并填写问题字段且不可编辑且最好不要提交。

如果我做

(r'^(?P<quiz_id>\d+)', QuizWizard.as_view(get_form_list)),

函数 get_form_list 没有长度

(r'^(?P<quiz_id>\d+)', QuizWizard.as_view(get_form_list(quiz_id))),

Quiz_id 未知。

所以现在我正在尝试将 quiz_id 传递给视图函数并生成要在表单向导中使用的问题表单列表

网址.py

url(r'^(?P<quiz_id>\d+)', 'quiz.views.get_form_list'),

视图.py

class QuizWizard(SessionWizardView):
    def done(self, form_list, **kwargs):
        return render_to_response('done.html', {
            'form_data':[form.cleaned_data for form in form_list],
        })

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

    question_forms = []

    for question in quiz.questions.all():        
        choices = []
        for choice in question.choices.all():
            choices.append(choice)
        f = QuestionForm(instance=question)        
        question_forms.append(f)

    return QuizWizard.as_view(question_forms)(request)

我收到错误消息

issubclass() arg 1 must be a class

根据 Rohan 的回答更新：

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

    question_forms = []

    for question in quiz.questions.all():        
        choices = []
        for choice in question.choices.all():
            choices.append(choice)
        f = QuestionForm(instance=question)        
        question_forms.append(f)

    inst_dict = {}
    for idx, question in enumerate(question_forms):
        inst_dict[str(idx)] = question
    print inst_dict
    #inst_dict = { str(index(x)) : x for x in question_forms}

    QuestFormList = []
    for i in range(len(question_forms)):    
        QuestFormList.append(QuestionForm)

    QuizWizard.as_view(QuestFormList, instance_dict=inst_dict)(request)

使用此代码，我收到错误

'ModelFormOptions' object has no attribute 'many_to_many'

这是我的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

您应该使用类而不是对象来调用它。所以把你的电话改成

QuizWizard.as_view(question_forms)(request)

更新：

向导视图将表单类列表作为参数而不是表单实例。您正在创建表单实例question_forms并将其传递给视图。

如果你想在每一步中为表单传递实例，你可以传递instance_dict. 就像是 ...

inst_dict = { '0': question_forms[0], #step 0 instance
              '1': question_forms[1], #step 1 instance
            }
QuestFormList = [QuestionForm, QuestionForm ...]
QuizWizard.as_view([QuestFormList, instance_dict=inst_dict)(request)
