Hi Omi: I think this should work:
put this in models/menu.py
response.menu = [
('Public', True, URL('index')),
('Member Only', False, URL('member')),
]
if (auth.user_id != None) and ((auth.has_membership(role = 'vip')) :
response.menu += [('VIP Only', False, URL('vip')), ]
NOT TESTED, but i think could help.
Bye.
