尝试在Django中保存多个文件：未返回HttpResponse对象。它返回了None

Question

请帮忙。我正在尝试使用CreateView在Django中保存多个文件。但是我只能将最后一个文件保存在所选列表中。然后，我将视图更改为与在此处看到的大多数解释都匹配的函数视图。.现在，我遇到了“值错误”。

下面是两个视图。 CreateView（CBV）和函数视图。 谢谢

CreateView

@method_decorator(login_required, name='dispatch')
class UpdateMatterCreateView(CreateView):
    form_class = UpdateMatterForm
    model = MatterUpdates
    template_name = 'matter/matter_instance_create.html'
    success_url = reverse_lazy('matter_list')

    def form_valid(self, form):
        form = UpdateMatterForm(self.request.POST, self.request.FILES)
        with transaction.atomic():
            form.instance.client_id = self.kwargs['client_id']
            form.instance.firm_id = self.kwargs['firm_id']
            form.instance.matter_id = self.kwargs['matter_id']
            form.instance.user_id = self.request.user.id

            files = self.request.FILES.getlist('files')

            for f in files:
                docs_path = Documents.objects.create(matter_update_id=self.kwargs['matter_id'], file_path=f)
                docs_path.save()

        return super(UpdateMatterCreateView, self).form_valid(form)


    def get_context_data(self, **kwargs):
        context = super(UpdateMatterCreateView, self).get_context_data(**kwargs)

        context['object'] = Matter.objects.get(id=self.kwargs['matter_id'])

        return context
