Question

Let me explain what I'm trying to do.

On stock module, when You navigate to whatever operation (picking) type, being it a tree or form view, some of the fields that are shown are from product.product, like, for example name.

Now, the model product.product has a field called price, so, I need to show product price on stock.picking movements.

Since the stock.picking model doesn't inherit the price field, I'm creating a little module, to inherit price from product.product, and then show it on stock.picking.

It is a third module beside stock and product.

Now, in my models.py I declare:

# -*- 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')

In my view.xml I add this field to 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>

Every time I try to run this, it throws me on console:

Any ideas on how can I achieve this?

I hope I've explained myself, if You need further explanation just ask me please.

Thanks in advance!

Answer 1

Try with following code:

Replace

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

with

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

And write below line in import section

import openerp.addons.decimal_precision as dp

Afterwards restart Odoo server and upgrade your custom module.

EDIT:

Replace

_inherit = 'stock.move'

with

_inherit = 'stock.picking'

Call field from inherited model Odoo v9 community
