TypeError: __init __() получил неожиданное ключевое слово аргумент «пароль»

Question

Я не могу выяснить, что является причиной этой ошибки

TypeError: __init__() takes at most 2 arguments (3 given) 

, которая указывает на

@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) 

LoginForm выглядит это:

class LoginForm(Form): 
    username = StringField("Username", validators=[DataRequired()]) 
    password = PasswordField('Password', validators=[DataRequired]) 
    remember = BooleanField("Remember Me", default=False)

Answer 1

Вы не называли одной из ваших валидаторов:

password = PasswordField('Password', validators=[DataRequired]) 

() Добавить:

password = PasswordField('Password', validators=[DataRequired()])
