Hi,

To add custom statuses to the Odoo Repair app, you simply need to extend the existing state field on the repair.order model. Odoo allows you to add extra selection values using selection_add, so you don’t need to override the entire field. After that, you can optionally create simple methods to switch to each new state. Once this is added in your custom module and the module is updated, the new statuses such as Waiting Parts, Waiting Confirmation, and Ready for Pickup will appear in the status field of the repair order form.

from odoo import models, fields

class RepairOrder(models.Model):

    _inherit = 'repair.order'

    state = fields.Selection(selection_add=[

        ('waiting_parts', 'Waiting Parts'),

        ('waiting_confirmation', 'Waiting Confirmation'),

        ('ready_pickup', 'Ready for Pickup'),

    ])

Hope it helps

you need to inherit the model and redefine the field like this:

class OriginalModel(models.Model):
	​_inherit = 'original.model'

	state = fields.Selection(selection_add=[
	​	​('waiting_parts', 'Waiting Parts'),
	​	​('ready', 'Ready'),
	​	​// and etc...
	​])
