[web2py] session.about[0].NodeNav.nodeID!=session.id error.

[Annet]

This code is part of a function:

session.about=db((db.NodeNav.nodeID==283)&(db.NodeNav.navID==db.Nav.id)&\
    (db.Nav.navbarID==ABOUTNAVBARID)).select(db.Nav.name,db.NodeNav.nodeID)
    print session.about

It prints:

Nav.name,NodeNav.nodeID
about,283
who_we_are,283
what_we_do,283
how_we_work,283

In the same function I have the following condition:

if not session.about or session.about[0].NodeNav.nodeID!=session.id:

... which results in the following error:

Traceback (most recent call last):

    if not session.about or session.about[0].NodeNav.nodeID!=session.id:
AttributeError: 'dict' object has no attribute 'nodeID'


Why cannot I compare session.about[0].NodeNav.nodeID!=session.id ?


Kind regards,

Annet.
