I was finishing up a simple user login with Flask and flask-Bcrypt. However, when trying to login with a user that is stored in my database, I keep getting this error
ValueError: Invalid salt
models.py
class User(db.Model):
__tablename__ = "users"
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String, nullable=False)
email = db.Column(db.String, nullable=False)
password = db.Column(db.String, nullable=False)
posts = db.relationship("Post", backref="author", lazy="dynamic")
def __init__(self, name, email, password):
self.name = name
self.email = email
self.password = bcrypt.generate_password_hash(password)
def __repr__(self):
return '<User {}>'.format(self.name)
views.py
@app.route("/login", methods=["GET", "POST"])
def login():
form = LoginForm()
if form.validate_on_submit():
user = User.query.filter(User.name == form.username.data).first()
if user and bcrypt.check_password_hash(user.password, form.password.data):
flash("you were just logged in!")
login_user(user)
return redirect(url_for("home"))
else:
flash("bad username or password")
return render_template("login.html", form=form)
forms.py
class LoginForm(Form):
username = StringField('username', validators=[DataRequired()])
password = PasswordField('password', validators=[DataRequired()])
