从继承模型Odoo v9社区调用字段

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(它是一个树或窗体视图)时，显示的一些字段来自product.product，例如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模型没有继承price字段，所以我创建了一个小模块，从product.product继承price，然后在stock.picking上显示它。

它是stock和product之外的第三个模块。

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，我将这个字段添加到stock.picking中

<?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>

每次我尝试运行它时，它都会将我抛到控制台上：

对我如何做到这一点有什么想法吗？

我希望我已经解释过了，如果你需要进一步的解释，请问我。

提前感谢！

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')

使用

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

并在“导入”部分写下一行。

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。

编辑：

替换

_inherit = 'stock.move'

使用

_inherit = 'stock.picking'
