來自繼承的模型Odoo v9社區的調用字段

Question

讓我解釋我想要做的事情。

在stock模塊，當導航到任何操作（拾取）的類型，它是一個樹或表單視圖，部分被示出的字段是從product.product，像，例如name。

現在，型號product.product有一個字段price，所以，我需要顯示產品價格stock.picking運動。

由於stock.picking模型不繼承price場，我創建一個小模塊，爲繼承product.productprice，然後顯示它在stock.picking。

它是stock和product旁邊的第三個模塊。現在

，在我models.py我宣佈：

# -*- 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view.xml我這個字段添加到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> 

每次我嘗試運行此，它拋出我的控制檯：

關於如何實現此目的的任何想法？

我希望我已經解釋了我自己，如果您需要進一步的解釋，請問我。

在此先感謝！

Answer 1

與下面的代碼試試：

更換

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

與

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

而下面寫一行在進口部分

import openerp.addons.decimal_precision as dp 

然後重新啓動Odoo服務器升級您的自定義模塊。

編輯：

更換

_inherit = 'stock.move' 

與

_inherit = 'stock.picking'
