Pemanggilan Onchange on Server pada Pembuatan Addon Odoo 17

Kadang-kadang kita memerlukan onchange di mana datanya diambil dari server yang mungkin diubah oleh aplikasi lain saat kita membuat aplikasi dengan Odoo 17.

Pemanggilan onchange on server pada pembuatan aplikasi Odoo 17 adalah seperti pada penjelasan-penjelasan berikut ini

1. Start SSH Filesystem
   
2. Model asrama.student
