In the Sale Order Line table, I want to add columns Quantity on Hand from the Inventory tab in Product view afer the columns Product. To achieve this, I try to create a custom module with self.pool.get and browse method. The problem right now is it shows the error of invalid XML for view architecture. Please help me.

Here is my code

qty_available.py

from openerp.osv import fields, osv
from openerp import netsvc, tools, pooler
import openerp.addons.decimal_precision as dp

class qty_available_add(osv.osv):

    _inherit = "sale.order"

    _columns = {
        'qty_available': fields.float('Qty Disponible',digits_compute= dp.get_precision('Product UoS')),
    }

    def get_qty(self, cr, uid, id, product, context=None):
        wg_qty_avail = self.pool.get('product.product').browse(cr,uid,product,context=None).qty_available
        result['qty_available'] = wg_qty_avail


qty_available_add()

qty_available.xml

<?xml version="1.0" encoding="utf-8"?>
<openerp>
  <data>
    <record model="ir.ui.view" id="qty_available">
        <field name="name">sale.order.form</field>
        <field name="model">sale.order</field>
        <field name="inherit_id" ref="sale.view_order_form" />
        <field name="arch" type="xml">
            <xpath expr="/form/sheet/notebook/page/field[@name='order_line']/form/group/group/field[@name='product_id']" position="after">
                <field name="qty_available" />
            </xpath>
        </field>
    </record>
  </data>
</openerp>

Thank you very much

Use below code:

In qty_available.py

from openerp.osv import fields, osv
from openerp import netsvc, tools, pooler
import openerp.addons.decimal_precision as dp

class sale_order_line(osv.osv):

    _inherit = "sale.order.line"

    _columns = {
        'qty_available': fields.float('Qty Disponible',digits_compute= dp.get_precision('Product UoS')),
    }    

sale_order_line()

In qty_available.xml

<?xml version="1.0" encoding="utf-8"?>
<openerp>
  <data>
    <record model="ir.ui.view" id="view_sale_order_line_form_inherit">
        <field name="name">view.sale.order.line.form.inherit</field>
        <field name="model">sale.order</field>
        <field name="inherit_id" ref="sale.view_order_form"/>
        <field name="arch" type="xml">

    <xpath expr="/form/sheet/notebook/page[@string='Order Lines']/field[@name='order_line']/form/group/group/field[@name='product_id']" position="after">                    
                    <field name="qty_available" />
                </xpath>

        </field>
    </record>
  </data>
</openerp>

Thank you for your response. The module has been installed successfully. However, the column Quantity on Hand and it's associated value didn't show on the Sale Order Line table after the column Product. Do you have any suggestion?

The field "Qty Disponible" is displaying after the product field in sale order line(form) view. If you want to display the "Quantity on Hand" field value in the "Qty Disponible" field, you have to write onchange function.
