Hi Marin,
we've found a temporary solution for this problem until they fix it in
web2py.
Here are some code excerpts from gluon/tools.py
def login_user(self, user):
"""
login the user = db.auth_user(id)
"""
from gluon.settings import global_settings
if global_settings.web2py_runtime_gae:
user = Row(self.db.auth_user._filter_fields(user, id=True))
delattr(user,'password')
else:
user = Row(user)
for key,value in user.items():
if callable(value) or key=='password':
delattr(user,key)
current.session.auth = Storage(
user = user,
last_visit=current.request.now,
expiration=self.settings.expiration,
hmac_key=web2py_uuid())
self.user = user
self.update_groups()
def update_groups(self):
if not self.user:
return
user_groups = self.user_groups = {}
if current.session.auth:
current.session.auth.user_groups = self.user_groups
table_group = self.table_group()
table_membership = self.table_membership()
memberships = self.db(
table_membership.user_id == self.user.id).select()
for membership in memberships:
group = table_group(membership.group_id)
if group:
user_groups[membership.group_id] = group.role
Function update_groups raises the error, we don't know why.
It stores the user's groups in a dict, this dict is used only by wiki
functions in gluon/tools.py.
has_membership doesn't use this dict, it creates a new select query.
So the simplest solution is to comment out or remove self.update_groups()
from login_user function.
Or like we did, create a new Auth class with an empty load_user function.
modules/auth2.py
#!/bin/python
# -*- coding: utf-8 -*-
from gluon.tools import Auth
class Auth2(Auth):
def __init__(self,
environment,
db=None,
controller='default'):
super(Auth2, self).__init__(environment, db, controller)
def update_groups(self):
return
And in db.py
#auth = Auth(db)
exec('from applications.%s.modules.auth2 import Auth2' % request.application
)
auth=Auth2(globals(),db)
Regards,
Oliver
