I found out that you can create field using ORM method even compute field. i think creating a widget is better but good to know that wen can create costum fields .

Hope this helps you

Note i didn't create a menu for person record but you can see the view by clicking on the owner_id in the car form if the new one2many field not shown just refresh the page.
