Python 使用flask security确认注册时出错

我正在使用flask security来处理用户注册、登录等。在使用默认flask security视图注册新用户时，我面临一个问题

编辑 我设法在解决这个问题上取得了一些进展。最初的问题是我没有提供load_用户回调。现在我在做：

@login_manager.user_loader
def load_user(user_id):
    return User.objects.get(id=user_id)

问题是确认url/视图似乎使用了匿名用户，因此，查询筛选器与正确的用户不匹配。有线索吗，伙计们

起初的 我能够在注册视图中提供用户邮件和密码，我成功地收到了确认电子邮件（flask security提供的默认模板），但当我尝试确认帐户时，单击邮件确认链接，我得到以下属性错误：

AttributeError: 'AnonymousUserMixin' object has no attribute 'roles'

以下是完整的回溯：

以下是我的应用程序配置：

from flask import Flask
from flask.ext.security import MongoEngineUserDatastore, Security
from flask_login import LoginManager
from flask_mail import Mail

from wpapp.models import db, User, Role
from wpapp.views import frontend
from wpapp.configs import CONFS


login_manager = LoginManager()
app = Flask(__name__)

app.config["MONGODB_SETTINGS"] = CONFS['MONGODB_SETTINGS']
app.config["SECRET_KEY"] = CONFS['SECRET_KEY']
app.config['SECURITY_PASSWORD_HASH'] = CONFS['SECURITY_PASSWORD_HASH']
app.config['SECURITY_PASSWORD_SALT'] = CONFS['SECURITY_PASSWORD_SALT']
app.config['SECURITY_REGISTERABLE'] = CONFS['SECURITY_REGISTERABLE']
app.config['SECURITY_CONFIRMABLE'] = CONFS['SECURITY_CONFIRMABLE']
app.config['SECURITY_RECOVERABLE'] = CONFS['SECURITY_RECOVERABLE']
app.config['SECURITY_REGISTER_URL'] = CONFS['SECURITY_REGISTER_URL']
app.config['MAIL_SERVER'] = CONFS['MAIL_SERVER']
app.config['MAIL_PORT'] = CONFS['MAIL_PORT']
app.config['MAIL_USE_SSL'] = CONFS['MAIL_USE_SSL']
app.config['MAIL_USERNAME'] = CONFS['MAIL_USERNAME']
app.config['MAIL_PASSWORD'] = CONFS['MAIL_PASSWORD']

mail = Mail(app)
app.register_blueprint(frontend)

db.init_app(app)

user_datastore = MongoEngineUserDatastore(db, User, Role)
security = Security(app, user_datastore)

login_manager.init_app(app)

if __name__ == '__main__':
    app.run()

下面是我的模型定义（我使用的是mongodb）：

有人知道问题出在哪里吗？

提前谢谢

我不确定您的确切问题是什么，但flask principal似乎正试图像身份验证用户一样使用

匿名用户

（无人登录时内存中的身份）。

匿名用户

没有

角色

属性，因此当它试图访问它时，会抛出一个异常。

谢谢deadbeef404，非常成功。我会对你的答案发表评论，但我没有任何代表

实际上，flask登录使用它自己的AnonymousUserMixin类。下面的代码片段显示了如何使用flask security的AnonymousUser类覆盖它

login_manager = LoginManager()
from flask.ext.security import AnonymousUser
login_manager.anonymous_user = AnonymousUser

谢谢你的回答！你能猜到怎么解决吗？我想我不久前遇到了这个问题或是一个非常类似的问题，但不幸的是我记不太清楚了。我遇到了这么多这样的事情，我不得不深入研究flask/flask security/flask principal等的源代码。唯一的选择是真正深入研究自己，并尝试找出发生了什么。这是我仍然喜欢Django而不是flask的原因之一；Django用户系统都包装得很好，可以实现基本功能。谢谢！我正设法四处挖掘。问题似乎是，我应该将flask登录匿名用户设置为flask安全匿名用户，并提供一个自定义加载用户函数。我正试着这么做。再次感谢您的时间广告帮助！

login_manager = LoginManager()
from flask.ext.security import AnonymousUser
login_manager.anonymous_user = AnonymousUser
