数据列表

{{ item }}

效果展示

列表页面默认显示列

如果没有数据，需要默认显示列
修改服务v1.py代码

    def changelist_view(self, request):
        """
        列表页面
        :param request:
        :return:

                verbose_name = self.model_class._meta.get_field(key).verbose_name
                header_list.append(verbose_name)
        else:

                'body_list': body_list
            }

列表页面预留钩子方法
