[web2py] Exporting foreign keys as represented value

[joe]

Hello

I am working with xlwt and trying to export a table of mine into a .xls 
file.  This table contains some foreign keys, and they are being exported 
as the id of the other table rathan than the 'name' field, which is what I 
want to display.  I define the foreign key fields in the table like this:


Field('owner', db.person, requires = IS_EMPTY_OR(IS_IN_DB(db, db.person, 
'%(name)s')), represent=lambda id, row: db.person(id).name if id else ' '),

Thanks!
