Dear all,

I set a tracking=True in an one2many field of child model by Odoo17 community. I followed the link How to use track_visibility='onchange' on order lines fields [odoo14] and edited the code in the child model.

When running, below error popped up. 

if set(vals) & set(self._get_tracked_fields(vals)):

                       ^^^^^^^^^^^^^^^^^^^^^^^^

AttributeError: xxx' object has no attribute '_get_tracked_fields'

Could someone advise how I can get child's model "tracking=True" working at the parent model or fix this error?
