Question

我想扩展sale.order.line模型的onchange_product_id方法。我尝试用新的和旧的api风格做，但没有任何效果。以下是我的尝试：

老pi：

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

尝试这种方式（我还没试过，但它应该有效）

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)

如何在Odoo 8的sale.order.line中的onchange_product_id方法中添加功能？
