I wonder why the IS_IN_DB() validator doesn't suit your needs.
I have a field day:
Field('day', 'reference cal_day', default=None, required=True,
requires=IS_IN_DB(db, 'cal_day.id', '%(id)s %(name)s', zero='Select a day'),
ondelete='RESTRICT', notnull=True, label='Day *'),
Doesn't zero = '*Whats your place of operations?'* do what you want?
