add one2many field in inherited class odoo 15

Question

Good day everyone,
In custom module I inherited sale.order to add a few columns, however it does not add the one2many column.  Any idea what could be wrong?
Table sale_status exists and has a field called xorder_id

xstatus_line = fields.One2many('sale.status', 'xorder_id')

on  module update no errors displays

thanks in advance.

Hi,
Please check the below example
Create new model ‘sale.status’
Class SaleStatus(models.Model):
_name = "sale.status"
xorder_id = fields.Many2one('sale.order', ‘Order’) Inherit sale order to add One2Many field
Class SaleOrder(models.Model):
_inherit = "sale.order"
xstatus_line  = fields.One2Many('sale.status, ‘xorder_id’, ’Lines’)

reply to myself, the column xstatus_line is not created on the table but its works.  I guess thats the way odoo function internally.
