Hello,

I want to do a simple test : trigger an onchange on res_partner model, and it never trigerred !

Module is installed, without errors.

Here is my code ( res_partner.py ) : 

from odoo import fields, models, api


class res_partner(models.Model):
    _name = 'res.partner'
    _inherit = ['res.partner']
    
    @api.onchange('name')
    def _onchange_name(self):

        self.name = self.name + "xxx"

        return {
            'warning': {
                'title': "name",
                'message': "Name was changed",
            }
        }

__init__.py code from package models :

import res_partner

root __init__.py code :

from . import models

Here is my strucure :

test

    >__init__.py

    >__manifest__.py

    >static

    >models

        > __init__.py

        > res_partner.py

Thanks.
