如何在 Odoo 8 中向 sale.order.line 中的 onchange_product_id 方法添加功能？

Question

我想扩展 sale.order.line 模型的 onchange_product_id 方法。我试着用新旧 api 风格来做，但没有任何效果。这是我的尝试：

旧 api:

import logging
from openerp.osv import fields, osv

_logger = logging.getLogger(__name__)

class sale_order_line(osv.osv):
    _inherit = 'sale.order.line'

    def onchange_product_id(self, cr, uid, ids, product_id, context=None):
        _logger.debug('product_id has changed')
        return {}

新 api:

from openerp import models, fields, api
import logging

_logger = logging.getLogger(__name__)

class sale_order_line(models.Model):
    _inherit = 'sale.order.line'

    @api.onchange('product_id')
    def onchange_product_id(self):
        _logger.debug('product_id has changed')
        return True

Answer 1

试试这个方法（我还没试过，但应该可以）

from openerp.osv import fields, osv

class CustomSaleOrderLine(osv.osv):
    _inherit = 'sale.order.line'

    def product_id_change(self, cr, uid, ids, pricelist, product, qty=0,
            uom=False, qty_uos=0, uos=False, name='', partner_id=False,
            lang=False, update_tax=True, date_order=False, packaging=False, fiscal_position=False, flag=False, context=None):

        # some operations

        return super(CustomSaleOrderLine, self).product_id_change(cr, uid, ids, pricelist, product, qty,
            uom, qty_uos, uos, name, partner_id,
            lang, update_tax, date_order, packaging, fiscal_position, flag, context)
