admin中的layer弹出层问题

我写了一个通用的批量修改模型的方法，想把这个方法从单个模型抽离到通用的公共组件中，但是在公共组件中，layer无法正常获取。

    def querysets_update_config(self, request, queryset):
        return {
            'title': '测试批量修改',
            'params': [{
                'type': 'radio',
                'key': 'type',
                'label': '修改类型',
                'require': True,
                'value': 1,
                'options': [{
                    'key': 1,
                    'label': '更新'
                }, {
                    'key': 0,
                    'label': '新增'
                }]
            }, {
                'type': 'checkbox',
                'key': 'ck',
                'label': 'Checkbox',
                'require': True,
                'value': [1],
                'options': [{
                    'key': 1,
                    'label': '更新'
                }, {
                    'key': 0,
                    'label': '新增'
                }]
            }]
        }

    @layer(querysets_update_config)
    def querysets_update(self, request, queryset):
        # 这里的queryset 会有数据过滤，只包含选中的数据
        post = request.POST
        field_name = post.get('field_name')
        # print(field_name)
        old_value = post.get('old_value')
        new_value = post.get('new_value')
        # post中 _selected 是选中的数据，逗号分割
        if not post.get('_selected') and post.get('select_across') == '0':
            return JsonResponse(data={
                'status': 'error',
                'msg': '请先选中数据！'
            })
        else:
            kwargs = {f'{field_name}__icontains': old_value}
            queryset = queryset.filter(**kwargs)

            return JsonResponse(data={'status': 'success','msg': '处理成功！'})

查看后台报错如下
