Hello.

I want to add a custom field to my purchase order form (Product Weight) to store the weight of every product I purchase. I would like to show this field's value for every product purchased in Stock Move Tree.

I have created a custom field (Product Weight) to my Purchase Order Form and a related one (Stock Weight) to Stock Move Tree. I created two modules and when I create a new purchase order everything works fine, but when I view Stock Moves I see the related field but it's empty.

Any help is appreciated!

Here is the code.

Module: Product Weight

File: product_weight.py

*****************

from openerp.osv import fields, osv

class product_weight(osv.osv):

_inherit = "purchase.order.line"

_columns = {

'x_product_weight': fields.float('Product Weight')

}

product_weight()

*********************

File: product_weight.xml

*********************

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

<openerp>

<data>

<record id="product_weight_field" model="ir.ui.view">

<field name="name">order.line</field>

<field name="model">purchase.order</field>

<field name="inherit_id" ref="purchase.purchase_order_form"/>

<field name="arch" type="xml">

<xpath expr="/form/sheet/notebook/page/field/tree/field[@name='pric$

<field name="x_product_weight" />

</xpath>

</field>

</record>

</data>

</openerp>

Module: Stock Weight

File: stock_weight.py

**********************

from openerp.osv import fields, osv

class stock_weight(osv.osv):

_inherit = "stock.move"

_columns = {

'x_stock_weight': fields.many2one('purchase.order.line','Stock Weight'),

}

stock_weight()

<field name="arch" type="xml">
