I am not sure how to track partner_id in accounting. My code:
from openerp import api, fields, models, _
class TwojStary(models.Model):
_inherit = 'res.partner'
bukcirra = fields.Monetary(string='Amount Due', currency_field='company_currency_id',
related='account.invoice.partner_id.residual_company_signed', store=True, help="Remaining amount due in the currency of the company.")
This is wrong I guess:
related='account.invoice.partner_id.residual_company_signed'
