Django，我不能将函数表单放入 generic.UpdateView

Question

我正在为我所在城市的一所幼儿园制作应用程序。我有儿童模型和付款模型。 为了更新孩子，我正在使用基于类的视图通用 UpdateView，为了创建付款，我正在使用表单和函数视图。当我使用不同的模板时，我的付款表格没有问题，但是当我尝试将其放在同一个模板上时，付款表格没有显示并且它不起作用。是否可以在与 UpdateView 类相同的模板上使用付款表格？我正在使用 UpdateView 类作为个人资料页面，我希望在同一页面上有付款表格。请帮忙。谢谢

class UpdateKidView(UpdateView):
    model = Kids
    form_class = KidsForm
    second_form_class = PaymentForm
    template_name = 'vrtic/update_kid.html'
    success_url = reverse_lazy('vrtic:kids')

    def get_context_data(self, **kwargs):
        context = super(UpdateKidView, self).get_context_data(**kwargs)
        context['form'] = self.form_class(instance=self.get_object())
        context['second_form'] = self.second_form_class()
        return context

    def post(self, request, **kwargs):
        kids_form = self.form_class(request.POST, request.FILES, instance=self.get_object())
        if kids_form.is_valid():

              ...
