Apply domain in Many2One

[Peter Müller]

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'))])

And what is not working?
For me, you have just forgot to add 'code' to depends.
And instead of 'code', you could use 'id'.

Ok, got this know. May I ask, the drop down selection shows only the code. Is it possible to show other fields (name, etc) ?

Thank you.

Just remove the widget="selection" to use the default Many2ONe widget
which provides this functionality.

IIRC the selection widget only shows the party rec_name

P.S: Don't top post in this mailing list. See

They both only show the rec_name which represent the name of the record.
I do not know but maybe it could be a feature to allow to define a
different Char field than the rec_name. But it will depend on how easy
it is.
