Hello Vootipong Limpanitivat,


For that you need to inherit sale.order.line object and use xpath to display in sale order form view. 

In PY:-

class SaleOrderLine(models.Model):

     _inherit = 'sale.order.line'


     x_field = fields.Char('X Field')


In Xml:-

<record model="ir.ui.view" id="sale_order_view_inherit">
    <field name="name">sale.order.view.inherit1</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']/tree/field[@name='name']" position="after">
            <field name="x_field"/>
        </xpath>
    </field>
</record>


This fields shows after Description in the sale order line.


Hope it will helps you.

Thanks,

Similar to Jignesh Metha, but in my code, I use this <xpath>.

<xpath expr="//page[@string='Order Lines']/field[@name='order_line']/tree[@string='Sales Order Lines']/field[@name='tax_id']" position="after">

  <field name="x_field"/>

</xpath> 

It works for me.

In Odoo/OpenERP we can inherit or use existing modules object/class/model and views. We can also inherit single field of existing modules. The question is why we need such inheritance.

The purpose of inheritance or why we need inheritance is given below:

  • To change attributes of some fields which exists on existing/custom model (e.g. making fields readonly,invisible)

  • To add/modify/delete old or new fields in existing/custom model (e.g. Product, Sales, HR, Fleet Management, Attendance modules model etc)

  • We can also add buttons in already existing/custom model (form and tree) view by using inheritance
