Presumably session.account is not always defined -- first you have to save 'account' to the session, so any request before that happens won't include 'account' in the session.
session is a Storage() object, so when you attempt to access keys that are not defined, it simply returns None. That's why session.account doesn't produce an error, even if 'account' hasn't been defined. However, session.account.id produces an error because session.account is None, and None does not have an attribute named 'id'. What do you want the default to be in case there is no 'account' in session? Maybe something like: default=session.account and session.account.id or None Anthony On Dec 6, 2:06 am, lyn2py <lyn...@gmail.com> wrote: > Reference post: > Scope authenticated users in > accountshttps://groups.google.com/group/web2py/browse_thread/thread/4e2bfa3f4... > > I used fishwebby's method to scope authenticated users.
