I can't find out what's the cause of this error
TypeError: __init__() takes at most 2 arguments (3 given)
which is pointing to
@user_blueprint.route('/login', methods=['GET', 'POST'])
def login():
if g.user.is_authenticated:
flash("You are already Logged in", 'warning')
return redirect(url_for('members'))
error = ""
form = LoginForm()
if request.method == 'POST':
if form.validate_on_submit():
user = User.query.filter_by(username=form.username.data).first()
if user is not None and bcrypt.check_password_hash(user.password, form.password.data):
login_user(user, remember=form.remember.data)
flash('You are sucessfuly Logged in', 'success')
return redirect(url_for('members'))
else:
error = "You have entered an incorrect username and password"
return render_template("front/login.html", forms=form, error=error)
The LoginForm
looks like this:
class LoginForm(Form):
username = StringField("Username", validators=[DataRequired()])
password = PasswordField('Password', validators=[DataRequired])
remember = BooleanField("Remember Me", default=False)
