here si my code :



def invitation():
    form=FORM("Code Invitation :", INPUT(_name='invitation'),"<Email 
:",INPUT(_name='email'),  INPUT(_type='submit'))
    if form.process(onvalidation=verif_invitation).accepted and  
form.vars.invitation != None  :
        email = form.vars.email
        if db(db.auth_user.email == email).count() == 0:
            password= form.vars.invitation  
            my_crypt = CRYPT(key=auth.settings.hmac_key)
            crypt_pass = my_crypt(password)[0]  
            john = db.auth_user.insert(
               email= email,
               username="John_Doe",
               password=crypt_pass,
               invitation = form.vars.invitation,
            )
            db.commit()  


            auth.user = Storage(auth.settings.table_user._filter_fields(john, 
id=True))

#line 686 where the bug is ????????????????
            auth.environment.session.auth = Storage(user=john, 
last_visit=request.now,
                                                
expiration=auth.settings.expiration)
            redirect(URL('inscriptioninvit'))
    return dict(form=form)
