hello one and all,
ok, under the DAL model, say i have a county and zip code table, like, as
defined as:
db_region.define_table('county',
Field('country_id', db_region.country, requires=IS_IN_DB(db_region,
db_region.country.id, '%(country)s'), writable=False, readable=False),
Field('state_id', db_region.state, requires=IS_IN_DB(db_region,
db_region.state.id, '%(state)s'), writable=False, readable=False),
Field('county', length=64, requires=NE, comment='county'),
...
and
db_region.define_table('post',
Field('country_id', db_region.country, requires=IS_IN_DB(db_region,
db_region.country.id, '%(country)s'), writable=False, readable=False),
Field('state_id', db_region.state, requires=IS_IN_DB(db_region,
db_region.state.id, '%(state)s'), writable=False, readable=False),
Field('county_id', db_region.county, requires=IS_IN_DB(db_region(
*db_region.post.state_id==db_region.county.state_id*), db_region.county.id,
'%(county)s'), comment='county'),
Field('city', length=64, requires=NE, comment='city'),
Field('post', length=11, requires=NE, comment='zip or postal code'),
see what i am trying to do in the bold? i am trying to limit the counties
listed in the subsequent SQLFORM select/options to only those counties that
are in the state.
when i try to compile i get an error, specifically an AttributeError. any
suggestions? thanx in advance, lucas
