There are two problems in the following codeL
db.define_table('state',
Field('country_id', db.country),
Field('name', unique=True),
# Field('full_name',compute=lambda row: row.country_id, unique=True),
format = '%(name)s')
#db(db.country.id==r['country_id']).select().first().name
#class StateVirtualFields(object):
# def namecountryid(self):
# return str(self.state.country_id)+self.state.name
#db.state.virtualfields.append(StateVirtualFields())
#db.state.full_name = Field.Virtual(lambda row: row.country_id)
db.state.fullname.compute = lambda row: str(row.country_id)+row.name
1. db.state.fullname.compute doesnot work at all.
2. if I use Field('full_name',compute=lambda row: row.country_id,
unique=True), for some reason it does *NOT* access country_id properly.
Please Help.
Regards.
