Flask 登录和“current_user.is_authenticated”不工作

Question

我在一个烧瓶应用程序中工作，我在登录时遇到问题。创建新帐户并将其添加到 sqlite 数据库后，我尝试登录，登录似乎接受我提供的任何密码。此外，

current_user.is_authenticated

方法不起作用贝洛是与登录页面相关的所有代码。

模型.py

from flaskblog import db, login_manager
from datetime import datetime
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}')"

路线.py

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




@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():
    if current_user.is_authenticated:return redirect(url_for('home'))
    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('Account created succefuly, you can now login', 'success')
    return redirect(url_for('login'))
        
        
    return render_template('register.html', title='Register', form=form)

我尝试输入错误的密码并登录。我期待一个身份验证失败的错误。
