Hi,
Please try with the below domain. Add it into the child product id field.
domain="[('category_id', '=', parent.category_id)]"
Hope it will help you.
Up vote please.
Invalid composed field farm_materials.category_id in domain of ([('categ_id', '=', farm_materials.category_id)])
also
ValueError: Invalid composed field materials.category_id in domain of ([('categ_id', '=', materials.category_id)])
No Not that way.
you have to use the "parent" key on a right side of the domain. Not 'farm_materials' or 'materials'.
please take the reference from here :
