Hi,

Refer to the blog on creating and configuring server actions for detailed guidance: How to Create and Configure Server Actions in Odoo 17.

Here is the code to be used in your server action method:

def custom_server_action(self):

matching_record = self.env['your.custom.model'].search( [

('x_estado', '=', 7),

('x_marcanew', '=', self.x_dispmarca),

('x_modelonew.x_mprimario', '=', self.x_dispmodeloprim)

], limit=1)

# Assign the found record to the Many2one field

if matching_record:

self.x_related_record_id = matching_record.id

Hope it helps
