功能字段在OpenERP中不起作用 [英] Function field is not working in OpenERP

问题描述

在purchase.order.line中，我添加了新字段pln price，并将单价字段更改为功能:

In purchase.order.line I added new field pln price and changed unit price field to function:

'price_unit': fields.function(_amount_pln, string='Unit Price', required=True, digits_compute= dp.get_precision('Product Price')),
'plnprice': fields.float('PLN Price', digits_compute= dp.get_precision('PLN Price')),

这是功能:

def _amount_pln(self, cr, uid, ids, prop, arg, context=None):
    res = {}
    for line in self.browse(cr, uid, ids, context=context):
        res[line.id] = line.plnprice * 0.25
    return res

现在，

交换值已进行硬编码，如_amount_pln函数中所示0.25

exchange value now is hardcoded, 0.25 as you see in _amount_pln function

然后我在purchase.order类中添加了新字段:

Then I added new field in purchase.order class:

'exchange_value': fields.float('Exchange',readonly=False)

但是我不知道如何将该字段值添加到我的_amount_pln函数中. 您能帮我解决这个问题吗?

But how get this field value to my _amount_pln function I don't know. can you please help me how to resolve this problem?

推荐答案

"purchase.order"和"purchase.order.line"之间的关系是"order_id". "purchase.order.line"包含"order_id".您可以使用此"order_id"获取"purchase.order"的值.

Relation between "purchase.order" and "purchase.order.line" is "order_id". "purchase.order.line" contains "order_id". You can get values of "purchase.order" using this "order_id".

for purchase_line in self.browse(cr, uid, ids, context=context):
    res[line.id] = purchase_line.plnprice * purchase_line.order_id.exchange_value
