Hi Guys,
I have simple database:
db.define_table('ipaddress',
Field('ip', unique=True, length=200),
Field('subnet', length=200),
format = '%(ip)s')
db.define_table('server',
Field('servername', length=200),
Field('port', length=200),
Field('ipaddress_id', 'reference ipaddress'))
I have few records in ipaddress table and not would like to add some
validators.
When adding record to server table i would like to check if ipaddress_id
exist in ipaddress table AND if it hasn't been used before in server table.
That can be done by doing:
db.server.ipaddress_id.requires = IS_IN_DB(db,db.ipaddress.id, '%(ip)s')
,IS_NOT_IN_DB(db,db.server.ipaddress_id, '%(ip)s')]
But in that case Filed server.ipaddress_id is not a dropdown menu and it's
not presented as %(ip)s. I would like to have dropdown to choose IP
available in ipaddress table, but just the one which hasn't been used
before. Any tips?
Thanks,
