python - 在同一 View 中使用多个表单

Question

我正在尝试使用一些示例应用程序来学习 Django 框架。目前，我正在处理反馈/调查应用程序。它使用以下模型:

class Survey(models.Model):
    title = models.CharField(_(max_length=255)
    slug = models.SlugField(_(max_length=255, unique=True)
    description= models.TextField(blank=True)


class Question(models.Model):
    survey = models.ForeignKey(Survey, related_name='questions')
    question = models.TextField()

class Answer(models.Model):
    question = models.ForeignKey(Question, related_name='answers')
    answer = models.TextField()

基本上，调查将包含问题，他们的答案将保存在答案中。

现在我不明白的是如何创建一个表单，该表单将在调用 View 时显示调查的所有问题。我试图创建这样的表单

class BaseAnswerForm(Form):
    answer = None
    def __init__(self, question,*args, **kwdargs):
        self.question = question
        #self.answer = None
        super(BaseAnswerForm, self).__init__(*args, **kwdargs)
        answer = self.fields['answer']
        answer.label = question.question

    def save(self, commit=True):
        ans = self.answer
        if ans is None:
            ans = Answer()
        ans.question = self.question
        ans.answer = self.cleaned_data['answer']
        if commit: ans.save()
        return ans

class TextAnswerForm(BaseAnswerForm):
    answer = CharField()

def forms_for_survey(survey, request):
    if request.POST:
        post = request.POST
    else:
        post = None
    return [TextAnswerForm(q,data=post)
            for q in survey.questions.all()]

这个的 View 是这样的

def show_questions(request, slug):
    survey = get_object_or_404(Survey.objects, slug=slug)
    forms = forms_for_survey(survey, request)
    context = {
        'survey':survey,
        'forms':forms,
        }
    if (request.POST and all(form.is_valid() for form in forms)):
        for form in forms:
            form.save()
        return HttpResponseRedirect(reverse('show_surveys',))
    return render_to_response(
        'feedback/show_questions.html',
        context,
        context_instance = RequestContext(request)
        )

它的作用是，它根据我的需要生成表单，但所有答案都保存在最后一个答案字段中。请帮助我，使用表单集会更容易吗，你能告诉我如何更容易地实现它吗？谢谢

Answer 1

原因可能是表单字段的名称冲突。

您可以解决该问题，但您是否已经查看了 Formsets Documentation ？

A formset is a layer of abstraction to working with multiple forms on the same page.
