golang pongo2 function 的问题

html

                <div class="layui-form-item">
                    {{form_label("登陆绑定 IP" ,label_cls)}}
                    <div class="layui-input-inline" data-name="{{optionSessionBindIp.Name}}" data-value="optionSessionBindIp.Value">
                        {{switch_option_render(optionSessionBindIp, fn_format("/a/admin/setting/update?name=%s",option.Name) )}}

                    </div>
                </div><!-- 登录绑定 IP -->

fn_format 的代码

func GinContextExtend(c *gin.Context, dataList ...pongo2.Context) pongo2.Context {
	// 可以把获取当前用户放在这里
	d := pongo2.Context{
		"fn_format": fmt.Sprintf,
	}
	user, err := service.GinGetUser(c)
	if err == nil {
		d["user"] = user
		menuList, err := ReadMenuList(user.Role)
		if err != nil {
			panic(err)
		}
		menuListByte, err := json.Marshal(menuList)
		if err != nil {
			panic(err)
		}
		d["menuList"] = string(menuListByte)
	}

	var newList = []pongo2.Context{
		d,
	}
	newList = append(newList, dataList...)

	return ContextExtend(newList...)
}

现在运行报错

该怎么弄呀, 在 macro 里面不能调用 function?

py 转来 golang 好不习惯呀
