Hi,

This is how we can add fields to any model by inheriting. I think, here you may be facing field does not exist error right ?

 If this is the case and if this happens on adding new field to partner model in an installed module, you should upgrade the module from command line by passing -u module_name

Hi kevin,

For adding a new field in the contact form first inherit the model and add corresponding field to it in python.After that add its view. find its external id of the corresponding view and add it on xml.

For example:

In python:

from odoo import models, fields, api
class ResPartner(models.Model):
    _inherit = 'res.partner'
    document_nit = fields.Char(string="NIT", required=True)

In xml:

<?xml version="1.0"?>

<odoo>

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

         <field name="name">res.partner.form.inherit</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='category_id']" position="after">

              <field name="document_nit"/>

             </xpath>

         </field>

    </record>

</odoo>
