Flask-login:AttributeError: 'User' object 没有属性 'is_active'

Question

我正在关注 Corey Schafer 的教程，每当我提交登录详细信息时，我都会收到错误 AttributeError: 'User' object has no attribute 'is_active'

注册工作正常

@app.route("/login", methods=['GET', 'POST'])
def login():
    form = LoginForm()
    if form.validate_on_submit():
        user = User.query.filter_by(email=form.email.data).first()
        if user and bcrypt.check_password_hash(user.password, form.password.data):
            login_user(user, remember=form.remember.data)
            return redirect(url_for('main'))
        else:
            flash('Login Unsuccessful check again')
    return render_template('login.html', title='Login', form=form)

from datetime import datetime
from main import db, login_manager
from flask_login import UserMixin


@login_manager.user_loader
def load_user(user_id):
    return User.query.get(int(user_id))




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(120), unique=True, nullable=False)
    image_file = db.Column(db.String(20), nullable=False,
                           default='default.jpg')
    password = db.Column(db.String(60), nullable=False)
    posts = db.relationship('Post', backref='author', lazy=True)

    def is_active(self):
        return True

    def __repr__(self):
        return f"User('{self.username}', '{self.email}', '{self.image_file}')"

Answer 1

那是因为您需要在User model 中添加列is_active 。 例如：

is_active= db.Column(db.Boolean, default=True, nullable=False)
