custom module, field does not exists in model odoo v16 sale.order

Question

Hi,
I'm trying to add an extra field to Sale Order form:
sale.py​:

from odoo import _, api, fields, models

class SaleOrderTest(models.Model):
​_inherit = "sale.order"
sale_test = fields.Char(string="Test", help="Test field")

record model="ir.ui.view" id="sale_order_am_excise">
excise.sale_order_am_inherit
sale.order

odoo service has been restarted, but always get error:

Field "sale_test" does not exist in model "sale.order"
View error context:
{'file': '/usr/lib/python3/dist-packages/

Thanks everyone!
Didn't add models to init.py.

Hello, visztani

I hope this message finds you well.

Make sure to add sales py file in init.py [1] .
Please find the attached screenshot to add a custom field in the sale order form view. I’ve added field Test after field Payment terms.

Feel free to contact me if needed
Hope this will help you.
Thanks & Regards,

Hello,
in you python module structure each directory contain a __init__.py in those file you should write a line with the file name wthout py extension as sample from . import sale
from . import xxxxxxx  where xxxxxx is the file name of your python file
