Hi ,

To add a new field to the Customer (i.e., res.partner) form view, you're on the right track by inheriting the model and extending the existing view. Here’s how you can do it:

1. Python Model

You've already done this part correctly. Your model should look like:

python

from odoo import api, fields, models

class Buyer(models.Model):

    _inherit = "res.partner"

    buyer_name = fields.Char(string='Buyer Name', required=True)

2. XML View Inheritance

Now, to show this field on the customer form, you can inherit the standard res.partner form view like this:

xml

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

    <field name="name">res.partner.inherit.buyer.name</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='barcode']" position="after">

            <field name="buyer_name"/>

        </xpath>

    </field>

</record>

Here, we’re adding the buyer_name field right after the existing barcode field. You can adjust the position depending on where you'd like it to appear.

3. Manifest File

To ensure your module loads the correct dependencies, add the following to your __manifest__.py:

python

'depends': ['contacts'],

This is important because the customer view (res.partner) is defined in the contacts module.

Hope it helps

find the module in which the res.partner model is created. In this case: 'depends': ['contacts']
