从继承的模型odoov9社区调用字段

Question

让我解释一下我想做什么。在

在stock模块中，当您导航到任何操作（拾取）类型时，无论它是树视图还是表单视图，显示的一些字段都来自product.product，例如name。在

现在，模型product.product有一个名为price的字段，因此，我需要显示stock.picking运动的产品价格。在

由于stock.picking模型没有继承price字段，所以我创建了一个小模块，从product.product继承{}，然后在stock.picking上显示。在

它是stock和product旁边的第三个模块。在

现在，在我的models.py中，我声明：

# -*- coding: utf-8 -*-

from openerp import models, fields, api

class StockMove(models.Model):
    _inherit = 'stock.move'

    @api.onchange('name','product_id','move_line_tax_ids','product_uom_qty')

    price_unit = fields.Float( digits_compute=dp.get_precision('Product Price'), string='Price')

在我的view.xml中，我将此字段添加到stock.picking：

^{pr2}$

每次我尝试运行这个时，它都会让我进入控制台：

有什么办法让我做到这一点吗？在

我希望我已经解释过了，如果你还需要进一步的解释，请你问我。在

提前谢谢！在

Answer 1

尝试使用以下代码：

更换

price_unit = fields.Float( digits_compute=dp.get_precision('Product Price'), string='Price')

与

^{pr2}$

在导入部分的下面一行写下

import openerp.addons.decimal_precision as dp

然后重新启动Odoo服务器并升级您的自定义模块。在

编辑：

更换

_inherit = 'stock.move'

与

_inherit = 'stock.picking'
