我有一个带有DataRequired验证器和相关错误消息的Flask-WTF表单.但是,Chrome浏览器似乎忽略了我的错误消息,只显示"请填写此字段".如何让Flask覆盖它并显示我的消息？

from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField
from wtforms.validators import DataRequired

class SignupForm(FlaskForm):
    first_name = StringField('First Name', validators=[DataRequired(message='Hey, put in your first name!')])
    last_name = StringField('Last Name', validators=[DataRequired("What, you can't remember your last name?")])
    email = StringField('Email', validators=[DataRequired('Gonna need your email address!')])
    password = PasswordField('Password', validators=[DataRequired('Really need a password, Dude!')])
    submit = SubmitField('Sign Up')
