Yes, exactly, I finally found the problem yesterday, gaeutlities session
behaves different on each object. So how about this solution: I have a base
handler class for all the handlers and what I added is to refresh the user
param from the datastore for every __init__ function. How that sounds?
class scRequestHandler(webapp.RequestHandler):
def __init__(self):
webapp.RequestHandler.__init__(self)
self.Session = scSession()
# reload the user object, this is because the refeernce property in
the Session
# object is somehow pickled and the put() operation does not update
the real entity.
# even though they have the same keys().
# The solution is to get the user from DS for every request.
if self.Session.user:
self.Session.user = db.get(self.Session.user.key())
