来自继承模型 Odoo v9 社区的调用字段

Question

让我解释一下我想做什么。

在 stock 模块上，当您导航到任何操作（选择）类型时，无论是树视图还是表单视图，显示的一些字段来自 product.product，例如，示例 name.

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

由于stock.picking模型不继承price字段，我正在创建一个小模块，从product.product继承price，然后显示它在 stock.picking.

它是 stock 和 product 之后的第三个模块。

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:

<?xml version="1.0" encoding="utf-8"?> 
<openerp>
<data>

<record id="view_stock_move_tree" model="ir.ui.view">
    <field name="name">Stock Move Price Tree</field>
    <field name="model">stock.picking</field>
    <field name="inherit_id" ref="stock.vpicktree"/>
    <field name="arch" type="xml">
        <field name="state" position="before">
            <field name="price_unit"/>
        </field>
    </field> 
</record>

<record id="view_stock_move_form" model="ir.ui.view">
    <field name="name">Stock Move Price Form</field>
    <field name="model">stock.picking</field>
    <field name="inherit_id" ref="stock.view_picking_form"/>
    <field name="arch" type="xml">
        <field name="state" position="before">
                <field name="price_unit"/>
            </field>
    </field>
</record>

</data>
</openerp>

每次我尝试运行这个，它都会让我进入控制台：

关于如何实现此目标的任何想法？

我希望我已经解释清楚了，如果您需要进一步的解释，请问我。

提前致谢！

Answer 1

尝试使用以下代码：

替换

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

和

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

并在导入部分的下面一行写上

import openerp.addons.decimal_precision as dp

之后重启 Odoo 服务器并升级您的自定义模块。

编辑：

替换

_inherit = 'stock.move'

和

_inherit = 'stock.picking'
