Python Flask 应用中 NameForm 对象为何没有 'validate_on_submite' 属性？

Question

python小白，今天按课本上的实例写了如下代码，运行后一直报错：AttributeError: 'NameForm' object has no attribute 'validate_on_submite'
，上网查之后说是可能导入了两个Form，导致后面的Form覆盖前面导入的Form，我仔细地核对了一遍，并没有发现这个问题，已经校对了一下午，仍不能运行，通过自查也不能解决，现向各位大佬求助。另外，我的VScode不能识别validate_on_submite，也不知道什么原因，截图如下：

from flask_wtf import FlaskForm
from wtforms import StringField, SubmitField
from wtforms.validators import DataRequired
from flask import Flask, render_template, session, redirect,url_for
# from collections.abc import Sequence
# import _collections_abc
# from typing import Any, Mapping




app=Flask(__name__)
app.config["SECRET_KEY"] = "123456"

class NameForm(FlaskForm):
    name = StringField('What is your name?', validators=[DataRequired()])
    submit = SubmitField('Submit')


@app.route("/",methods=["GET", "POST"])
def index():
    name=None
    form = NameForm()
    if form.validate_on_submite(): 
        name = form.name.data
        form.name.data = ''
    return render_template('index1.html', form=form, name=name)
    #     old_name=session.get("name")
    #     if old_name is not None and old_name !=form.name.date: 
    #         flash("看看你输入的什么")
    #     session["name"] = form_name_data
    #     return redirect(url_for("index"))
    # return render_template("index1.html",form = form, name = session.get("name"))


if __name__=="__main__":
    app.run(debug=True)

求助各位大佬

方法名称拼写错误,form.validate_on_submit(), 另外如果vscode不识别的话可以加上类型注解form: NameForm = NameForm()
