from wtforms import Form, BooleanField, TextField, validators,PasswordField class LoginForm(Form): username= TextField(\'Username\', [validators.Length(min=4, max=25)])
from wtforms import Form, BooleanField, TextField, validators,PasswordField
class LoginForm(Form):
    username     = TextField('Username', [validators.Length(min=4, max=25)])
    password = PasswordField('Password')

when i use LoginForm on webapp(gae) like this :

def post(self):
    form=LoginForm(self.request)

but it show error :

TypeError: formdata should be a multidict-type wrapper that supports the 'getlist' method

You are supposed to pass in self.request.form (the actual form fields, not the entire request)
