如何在单个视图中使用多个表单集？

Question

我需要为单个视图使用自定义表单的多个表单集。我知道您需要为表单集添加前缀，以便它们不会相互冲突。但是，当我尝试为表单集添加前缀时，会引发ValidationError。

我创建表单集的方法是将表单列表传递给视图，然后使用formset_factory创建FormSets列表。然后我创建一个初始化的表单集列表。

这是我的代码：

def edit_stuff2(request, business_id, template_name="business/edit_info.html",
                *args, **kwargs):
    business = BusinessDoc.get(business_id)
    FormSets=[]
    formsets=[]
    info_forms = [(EmailDocForm,'emails'), (URLDocForm,'urls')]
    for form in info_forms:
        FormSets.append(formset_factory(form[0], max_num =0,
                                        can_delete=True, extra=1))
    if request.user:
        if request.method == "POST":
            for FormSet,tup in zip(FormSets,info_forms):
                FormSet.form = staticmethod(curry(tup[0], business))
                formsets.append(FormSet(request.POST,prefix=tup[1],
                                        initial = business[tup[1]]))
                if formsets[-1].is_valid():
                    for form in formsets[-1].forms:
                        form.save()
                        #request.user.message_set.create(message=u"Check it")
            formsets = []
            for FormSet, tup in zip(FormSets, info_forms):
                FormSet.form = staticmethod(curry(tup[0], business))
                formsets.append(FormSet(prefix=tup[1], initial=business[tup[1]]))
        return direct_to_template(request, template=template_name,
                       extra_context={'business': business,
                                      'formsets': formsets,
                                      'info_type': info_type})
    else:
        return HttpResponseRedirect(reverse('home'))
