django - 尝试在 Django 中保存多个文件：没有返回 HttpResponse 对象。它返回 None 而不是

Question

请帮忙。我正在尝试使用 CreateView 在 Django 中保存多个文件。但我只能保存所选列表中的最后一个文件。然后我将我的视图更改为与我在这里看到的大部分解释相匹配的函数视图。现在我得到了值错误。

下面是两个视图。CreateView(CBV) 和函数 View。谢谢

创建视图

@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

功能视图

            content = form.instance.content
            created_date = form.instance.created_date
            created_time = form.instance.created_time

                                                              user_id=request.user.id, )
            matter_update_link.save()

            return redirect('matter_list')

        else:

        return render(request, 'matter/matter_instance_create.html', {'form': form})
