Answer 1

# -*- coding: utf-8 -*-

from openerp import models, fields, api

class old_residual(models.Model):

    _inherit = "account.invoice"

    old_residual = fields.Monetary(string='Nợ cũ',currency_field='company_currency_id', compute='_compute_o$


@api.multi
def _compute_old_residual(self):
for invoice in self:
    invs = self.search([('state', '=', 'open'), ('partner_id', '=', invoice.partner_id.id)])
    out_invoice = 0
    in_invoice = 0
    out_refund = 0
    in_refund = 0
    for inv in invs:
        if inv.type == 'out_invoice':
            out_invoice += inv.residual
        if inv.type == 'in_invoice':
            in_invoice += inv.residual
        if inv.type == 'out_refund':
            out_refund += inv.residual
        if inv.type == 'in_refund':
            in_refund += inv.residual
    invoice.old_residual = out_invoice + in_refund - in_invoice - out_refund - invoice.amount_total

Answer 2

在函数声明之后，您应该提供意图

@api.multi
def _compute_old_residual(self):
    for invoice in self:
        invs = self.search([('state', '=', 'open'), ('partner_id', '=', invoice.partner_id.id)])
