I know I'm late to the party, but I have to write to thank Anthony for
sharing such a wonderful trick!
One more thing, I happen to also discover that we do not have to use
lambda. The following form is less verbose, more intuitive.
db.define_table('room',
Field('room_no'),
Field('category', 'list:string'),
Field('status', 'list:string'),
Field('branch', 'reference branch'),
format='%(branch.address) %(room_no)s')
Thanks everyone, especially Massimo for building such an amazingly flexible
web2py!
Regards,
Ray
