I made help'er function to generate representation
def ref_repr(reffered_table):
return lambda foreign_key, self: reffered_table[foreign_key].name
so you can add representation this way:
Even when using the following it does not show the country name.
> Field('shipping_country','reference country',requires=IS_EMPTY_OR(
> IS_IN_DB(db, db.country.id,'%(name)s'), null=None),
>
> requires=ref_repr(db.country)),
>
