如何實例化一個formset的字段以預先填充？

Question

我的看法讓我現在看看我是否有兩個問題，它向我展示了兩種形式。我希望我現在可以實例化我的兩個表單，每個表單都有一個問題。以便用戶不再僅僅回答沒有選擇的問題...

我的看法。潘岳：

def access(request, instance): 
    replies = Reply.objects.all() 
    pages = Page.objects.all() 
    numPages = Page.objects.get(pk=instance) 
    questions = Question.objects.filter(page=instance) 
    length_questions = len(questions) 
    logged_user = get_logged_user_from_request(request) 
    ReplyFormSet = modelformset_factory(model=Reply, form=ReplyForm, extra=length_questions, can_delete=True) 
    formset = ReplyFormSet(request.POST, queryset=Reply.objects.none()) 
    if request.method == 'POST': 
     formset = ReplyFormSet(request.POST, queryset=Reply.objects.none()) 
     if formset.is_valid(): 
      new_instances = formset.save(commit=False) 
      for new_instance in new_instances: 
       new_instance.user = logged_user 
       new_instance.save() 
      return HttpResponseRedirect('/baseVisite/') 
     else: 
      messages.add_message(request, messages.INFO, 'Le formulaire est incorrecte !') 
      return render_to_response('polls/error.html', context_instance=RequestContext(request)) 
    else: 
     formset = ReplyFormSet(queryset=Reply.objects.none()) 
    return render_to_response('polls/access.html', { 
    'formset': formset, 
    'questions':questions, 
    'logged_user':logged_user, 
    'numPages' : numPages 
    }) 

我的models.py：

class Page(models.Model): 
    title = models.CharField(max_length=30) 


    def __str__(self): 
     return self.title 

class Question(models.Model): 
    label = models.CharField(max_length=30) 
    page = models.ManyToManyField(Page) 

    def __str__(self): 
      return self.label 

class Reply(models.Model): 
    question = models.ForeignKey(Question) 
    user = models.ForeignKey(Personne) 
    answer = models.CharField(max_length=30) 
    creationDate = models.DateTimeField(default=django.utils.timezone.now) 

    def __str__(self): 
     return str(self.answer) 

和我forms.py：

class ReplyForm(forms.ModelForm): 
    class Meta: 
     model = Reply 
     exclude = ('user','creationDate') 

我想用此過濾器預填充字段「問題」 - > Question.objects.filter（page = instance）是否可以放置這樣的過濾器？

可以使用的queryset參數
