Onchange untuk Perubahan Field Pembuatan Aplikasi Odoo 17

Ketika mengembangkan aplikasi menggunakan Odoo 17 kita biasa membuat tampilan di mana nilai suatu field bergantung dari field-filed lain. Di sini kita akan menggunakan onchange.

Penggunaan onchange untuk perubahan field pembuakan aplikasi Odoo 17 adalah seperti pada langkah-langkah berikut ini

1. Start SSH filesystem
   

   

2. Model asrama.student
   

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88
