Hi

Update the code,

In python:
from odoo import fields, models

class ResPartner(models.Model):
    _inherit = 'res.partner'

    district = fields.Char(string='District', size=32)
   
In XML:
<record id="add_new_partner" model="ir.ui.view">
<field name="name">new.customer.model</field>
<field name="model">res.partner</field>
    <field name="inherit_id" ref="base.view_partner_form"/>
    <field name="arch" type="xml">
        <xpath expr="//field[@name='vat']" position="before">
            <field name="district" placeholder="District"/>
        </xpath>
    </field>
</record>

Hope it helps

Please help

Hi Sharath,

You gave wrong value of '_name'. 

Instead of _name = 'new.customer.model' , you should use  _name = 'res.partner'.

Hope this will help you!

Thanks.
