整点
我正在尝试使用 Flask（菜鸟！）制作一个相当基本的网站，并且在用户登录系统方面遇到了麻烦。我决定要使用 Flask-Login、Flask-BrowserID (Mozilla Persona) 和 SQLAlchemy。我将让 Persona 成为负责存储用户密码等的部分，一旦用户通过身份验证，我将使用 Flask-Login 来跟踪他们的会话，我将使用 SQLAlchemy 将所有内容存储在一个 sqlite3 数据库。我做了很多弹跳，我想我几乎已经完成了这些功能，但我似乎无法找回特定的错误。
更新 1
根据 davidism 的评论，我不得不将 db.Model 添加到 User 类中。不幸的是，这解决了第一个错误，但现在有一个新错误要处理。追溯在下面找到。
问题
是什么赋予了？我显然错过了一些东西，但我似乎无法找到那是什么。
我一直在使用的资源
- Flask-BrowserID：https ://github.com/garbados/flask-browserid/wiki
- 烧瓶登录： http: //flask-login.readthedocs.org/en/latest/
- Flask-SQLAlchemy： http: //pythonhosted.org/Flask-SQLAlchemy/quickstart.html#a-minimal-application
- 是否可以在 SQLite 中存储 Python 类对象？
- SQLAlchemy 文档：http ://docs.sqlalchemy.org/en/rel_0_9/orm/tutorial.html
- 工作 Flask-BrowserID：https : //github.com/garbados/flask-browserid/blob/master/tests/init .py
附加信息
这是我与 Flask 一起使用的 main.py 和 index.html 以及我得到的 Traceback：
