Hi,
I try to put a reference from a party to a party. The referenced party will
be the party that will pay the invoices.
The field on the form is made as widget="selection".
I don't want that the user can select the same party as the refernced
party. So I want to apply the domain to show all parties, but the current.
Probably I have wrong the Eval expression and cannot found further
documentation.
Regards.
from trytond.model import fields
from trytond.pool import PoolMeta
from trytond.pyson import Eval
__all__=['Party']
__metaclass__ = PoolMeta
class Party:
__name__ = 'party.party'
payer = fields.Many2One('party.party','Payer',domain=[('code','!=',Eval(
'code'))])
