AttributeError：“用户”对象没有属性“is_active”烧瓶应用程序

Question

我正在尝试登录我的烧瓶应用程序。我尝试过调试，但没有发现任何错误。注册工作正常，当我使用错误的详细信息时，应用程序会引发验证错误，但是当我尝试登录时出现以下错误

我有以下routes.py

from flask import render_template, url_for, flash, redirect
from flaskblog.forms import RegistrationForm, LoginForm
from flaskblog.models import User, Post
from flaskblog import app, db, bcrypt
from flask_login import login_user


@app.route("/")
@app.route("/home")
def home():
    return render_template('home.html', posts=posts)


@app.route("/about")
def about():
    return render_template('about.html', title='About')


@app.route("/register", methods=['GET', 'POST'])
def register():
    form = RegistrationForm()
    if form.validate_on_submit():
        hashed_password = bcrypt.generate_password_hash(form.password.data).decode('utf-8')
        user = User(username =form.username.data, email=form.email.data, password=hashed_password)
        db.session.add(user)
        db.session.commit()
        flash('Your account has been created! you are now able to log in', 'success')
        return redirect(url_for('login'))
    return render_template('register.html', title='Register', form=form)


@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('home'))
        else:
            flash('Login Unsuccessful. Please check email and password', 'danger')
    return render_template('login.html', title='Login', form=form)

我已尝试运行我的 run.py 文件，但我一直在运行

AttributeError: 'User' object has no attribute 'is_active'

我的models.py如下

from datetime import datetime
from flaskblog 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 __repr__(self):
        return f"User('{self.username}', '{self.email}', '{self.image_file}')"


class Post(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(100), nullable=False)
    date_posted = db.Column(db.DateTime, nullable=False, default=datetime.utcnow)
    content = db.Column(db.Text, nullable=False)
    user_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)

    def __repr__(self):
        return f"Post('{self.title}', '{self.date_posted}')"

我来不及了，但是如果以后有人遇到同样的问题，那么可以通过在 User 类中编写你赢得的 is_active() 函数来简单地解决它

from flask_login import UserMixin

class User(db.Model, UserMixin):
        #code

    def is_active(self):
       return True


    def __repr__(self):
       return " "
