Question

我试图从我继承的模型中获取字段。

from openerp import api, fields, models

class Calculate(models.Model):
    _inherit = 'sale.order.line'
    company_discount = fields.Float(string='Company Discount')
    customer_discount = fields.Float(string='Customer Discount')
    company_price_amount_total = fields.Monetary(string='Price after discount', store=True, readonly=True, compute='_calc_company_price', track_visibility='always')
    customer_price_amount = fields.Monetary(string='Customer price', store=True, readonly=True, compute='_calc_customer_price', track_visibility='always')
    transport  = fields.Float(string='Transport')
    transport_amount = fields.Monetary(string='Transport amount', store=True, readonly=True, compute='_calc_transport', track_visibility='always')

    @api.depends('order_line.price_unit', 'customer_discount')
    def _calc_customer_price(self):
        self.customer_price_amount = self.order_line.price_unit * ((100 - self.customer_discount) / 100)

    @api.depends('order_line.price_unit', 'company_discount', 'customer_discount')
    def _calc_company_price(self):
         self.company_price_amount_total = self.order_line.price_unit * ((100 - self.customer_discount) / 100) * ((100 - self.company_discount) / 100)

    @api.depends('customer_price_amount', 'transport')
    def _calc_transport(self):
        self.transport_amount = self.customer_price_amount * ((100 - self.transport) / 100)

我收到错误 NameError: global name 'price_unit' is not defined。

字段price_unit位于我继承的模型sale.order.line中。

更新：

我已尝试price_unit和sale.order.line.price_unit但结果相同。

Answer 1

您不需要每次都写 order_line.price_unit ，但只需 price_unit

Answer 2

在py中添加继承是执行正确继承的两个步骤之一。我认为你缺少的是在 openerp .py文件中添加它。

在＆＃34;依赖＆＃34; attr add＆＃34; sale＆＃34;作为您继承的模块，因为它包含sale.order.line声明。
