《Flask Web Development》学习笔记---chapter4 Web Forms

1.  我们用 wrapper了WTForms的Flask-WTF扩展来处理表单生成和验证。


2.  Cross-Site Request Forgery (CSRF) 保护

配置config,‘SECRET_KEY‘


3. Form class definition

from flask.ext.wtf import Form
from wtforms import StringField, SubmitField
from wtforms.validators import Required

class NameForm(Form):
    name = StringFiled('what is your name?', validators=[Required])
    submit = SubmitFiled('Submit')



4. 标准 Fields

StringField
TextAreaField
PasswordField
HiddenField
DateField            Text field accepts a dattime.date value in a given format
DateTimeField   
IntegerField
DecimalField
FloatField
BooleanField
RadioField
SelectField
SelectMultipleField
FileField
SubmitField

5.  标准validators

卧槽,这个有点老,还是看WTForms的文档去吧。

IPAddress
Length
