Extend Method Write dan Create pada Kustomisasi Odoo

Kita mungkin ingin menambahkan logika tertentu pada method yang sudah ada misalnya function write dan create. Di sini kita akan melakukan extend method write dan create.

Extend method write dan create pada kustomisasi Odoo adalah seperti pada contoh berikut ini

1. Start SSH file system
   

   

2. Model asrama.room
   Pembatasan create dan write untuk pengisian field remark:
