缺少用户加载器或request_loader错误 [英] Missing userloader or request_loader error

问题描述

我遇到了烧瓶登录问题，用户加载程序不起作用

i have an isssue with flask-login the user loader is not working

Exception: Missing user_loader or request_loader. Refer to http://flask-login.readthedocs.io/#how-it-works for more info.

和当我尝试在shell中导入用户模型时:

and when i try to import the user model in shell:

AttributeError: 'LoginManager' object has no attribute 'load_user'

这是我的代码:

-------------------app/__init__.py----------------

from app.config import Config
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_login import LoginManager


#create app
app = Flask(__name__)
app.config.from_object(Config)

#init pckages
db = SQLAlchemy(app)
login_manager = LoginManager(app)

#import Blueprints
from app.blueprints.user.routes import user
from app.blueprints.dashboard.routes import dashboard

#register Blueprints
app.register_blueprint(user)
app.register_blueprint(dashboard)

------------------------------app.py-------------------------------
from app import app

if __name__ == "__main__":

    app.run(debug=True)
------------------------------user model------------------------------------
from app import db, login_manager
from flask_login import UserMixin


@login_manager.load_user
def load_user(user):
    return User.get(user)


class User(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(20), unique=True, nullable=False)
    email = db.Column(db.String(20), unique=True, nullable=False)
    avatar = db.Column(db.String(50), default="default.jpg")
    password = db.Column(db.String(60), nullable=False)


    def __repr__(self):
        return self.username

推荐答案

装饰器应该是

@ login_manager.user_loader 不是 load_user
