python tornado.web.uimodules没有用jinja2渲染

我在一个简单的web应用程序上运行龙卷风。目前，我正在尝试创建一个用户模块来显示base.html中包含的navbar.html组件上的登录用户信息。python tornado.web.uimodules没有用jinja2渲染

我创建了一个uimodules.py文件，添加我的菜单类

import tornado.web 

class Menu(tornado.web.UIModule): 
    def render(self): 
    return '<div>THE MODULE HAS ARRIVED</div>'

然后在我的app.py今年进口

from uimodules import Menu

在我的设置

快译通我

"ui_modules": {"Menu": Menu}

我的理解是，现在，菜单模块应该可以访问我的整个应用程序，我应该可以添加...

{% module Menu() %}

...标记包含此模块。当我运行该应用程序时，出现以下错误。
