如何在flask-admin中添加额外的字段？

Question

我知道使用form_extra_fields可以在flask-admin中添加一个额外的字段.但是我怎么能让它"需要"？提前致谢.

form_extra_fields = {
    'password2': PasswordField('Password')
}

Answer 1

非常感谢,机甲.其实我想出了一个更简单的方法:

from wtforms import validators
form_extra_fields = {
    'password2': PasswordField('password',[validators.DataRequired()])
}

Answer 2

您可以使用 WTForms。请参阅下面的示例，摘自Flask 的文档：

from wtforms import Form, BooleanField, TextField, PasswordField, validators

class RegistrationForm(Form):
    username = TextField('Username', [validators.Length(min=4, max=25)])
    email = TextField('Email Address', [validators.Length(min=6, max=35)])
    password = PasswordField('New Password', [
        validators.Required(),
        validators.EqualTo('confirm', message='Passwords must match')
    ])
    confirm = PasswordField('Repeat Password')
    accept_tos = BooleanField('I accept the TOS', [validators.Required()])
