You should subclass UserMixinon your model. You should also add a user_loader
您应该UserMixin对模型进行子类化。您还应该添加一个 user_loader
from flask.ext.login import UserMixin
from yourapp import login_manager
@login_manager.user_loader
def get_user(ident):
return User.query.get(int(ident))
class User(db.Model, UserMixin):
id = db.Column(db.Integer, primary_key=True)

From the Flask-login documentation, it specifically says:
从Flask-login 文档中，它特别指出：
"To make implementing a user class easier, you can inherit from UserMixin, which provides default implementations for all of these methods. (It's not required, though."
“为了更轻松地实现用户类，您可以从 UserMixin 继承，它为所有这些方法提供默认实现。（但这不是必需的。”
The methods refered will be: is_authenticated(), is_active(), is_anonymous()and get_id(), which by the look of your model, they are missing. Once you implement those functions to your model, there should be no problem with Flask-login.
引用的方法将是：is_authenticated()、is_active()、is_anonymous()和get_id()，从您的模型来看，它们是缺失的。一旦您将这些功能实现到您的模型中，Flask-login 应该没有问题。
