新添加的total_quantity field 回值显示0.00. 无报错,问题出在那里,请有经验的解答下, 求的值是全订单的物品数量值.谢谢 -
amount_all的返回值的数据格式错误。应该返回一个id-value的mapping。
res[order.id]=value -
添加return res[order.id]=value? 还是别的,请解释下,不太明白,谢谢

看来代码不是你写得
你现在返回的值是这样的：{ORDER_ID:{'total_quantity': QUANTITY_VAL}，...}
需要返回的值应该是这样的： {ORDER_ID: QUANTITY_VAL, ...} -
回的值还是不对,还是0.00,请指点

把你修改后的代码，贴出来，大家看看。修改后要重启服务器。
另外， 你这样的需求可以不用写function字段的，参考一下“会计凭证”表单中“分录明细”部分下面的“贷方合计”，“借方合计”。只要在销售订单表单视图中，订单行明细中 'product_uom_qty' 字段中添加“sum”属性就可以了。 -

'sale.order.line': (_get_order, ['product_uom_qty'], 10),
}, help="The total quantity", track_visibility='always'),
}
经修改和测试后能用的代码,谢谢大家指导.
6.1测试成功,如果已经建立的表单,需要修改表单里的产品数量(任意)并保存才能显示新的计算产品量 -
<br />for order in self.browse(cr, uid, ids, context=context): <br /> res[order.id] = {'total_quantity': 0.0,}
这段代码就不需要了。
