Python Flask - TypeError: __init__() 得到了一个意外的关键字参数“lable”

Question

I am using flask wtform to create a registration page:

form.py

from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField

class RegisterForm(FlaskForm):
    username = StringField(label='username')
    email_address = StringField(label='email')
    password1 = PasswordField(label = 'password1')
    password2 = PasswordField(label = 'password2')
    submit = SubmitField(lable='Submit')

Routing like this:

Route.py

from market import app
from flask import render_template
from market.models import Item
from market.forms import RegisterForm

@app.route('/')
@app.route('/home')
def home_page():
    return render_template('home.html')

@app.route('/register')
def register_page():
    form = RegisterForm()
    return render_template('register.html', form=form)

I am getting the following error:

TypeError: __init__() got an unexpected keyword argument 'lable'

Answer 1

它有可能是 label='Submit' 而不是 label='Submit' 吗？
