Question

我正在尝试使用表单向导，但我无法确定在哪里设置字段的选择。

#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，看起来像是用于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，不可编辑，最好不要提交。

如果我这样做

(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。

所以现在我试图将quiz_id传递给view函数并生成要在表单向导中使用的问题表单列表

urls.py

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

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],
        })

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。所以将你的电话改为

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question_forms中创建表单实例并将其传递给查看。

如果要在每个步骤中传递表单的实例，可以传递instance_dict。有点像...

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)

在运行时为表单向导设置选项和表单？

urls.py

views.py
