WTForms erreur: TypeError: formdata doit être un emballage de type multidict

Question

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

quand j'utilise LoginForm sur webapp (Gae) comme ceci:

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

mais il montre l'erreur:

Traceback (most recent call last): 
    File "D:\Program Files\Google\google_appengine\google\appengine\ext\webapp\__init__.py", line 513, in __call__ 
    handler.post(*groups) 
    File "D:\zjm_code\forum_blog_gae\main.py", line 189, in post 
    form=LoginForm(self.request) 
    File "D:\zjm_code\forum_blog_gae\wtforms\form.py", line 161, in __call__ 
    return type.__call__(cls, *args, **kwargs) 
    File "D:\zjm_code\forum_blog_gae\wtforms\form.py", line 214, in __init__ 
    self.process(formdata, obj, **kwargs) 
    File "D:\zjm_code\forum_blog_gae\wtforms\form.py", line 85, in process 
    raise TypeError("formdata should be a multidict-type wrapper that supports the 'getlist' method") 
TypeError: formdata should be a multidict-type wrapper that supports the 'getlist' method 

comment le faire fonctionner

merci

Vous êtes censé passer dans self.request.form (les champs de formulaire réels, pas la demande entière)
