Computed Field pada Pengembangan Aplikasi Odoo 17

Dalam melakukan pemrograman kita akan menjumpai field-field yang tidak dimasukkan oleh pengguna tetapi dihitung dari field-field yang lain. Begitu juga pada pengembangan aplikasi berbasis Odoo 17 ini kita menggunakan computed field untuk field-field yang dihitung berdasarkan nilai dari field-field lain.

Computed field pada pengembangan aplikasi Odoo 17 adalah seperti pada langkah-langkah berikut ini

1. Menjalankan SSH Filesystem
   

   

2. Model asrama.room
   

   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

   from odoo import fields, models, api, _ from odoo.exceptions import ValidationError   class AsramaRoom(models.Model):     _name = 'asrama.room'     _description = 'Informasi Kamar Asrama'     _rec_name = 'room_no'       name = fields.Char('Nama kamar',required=True)     room_no = fields.Char('No kamar',required=True)     floor_no = fields.Integer('No Lantai',default=1, help='No Lantai')     currency_id = fields.Many2one('res.currency',string='Mata uang')     rent_amount = fields.Monetary('Harga sewa',help='Masukkan harga sewa')       hostel_id = fields.Many2one('asrama.hostel','Hostel', help='Nama hostel')          student_per_room = fields.Integer('Jml pelajar per kamar',required=True,         help='Jml yang dialokasikan per kamar')       @api.depends('student_per_room','student_ids')     def _compute_check_availability(self):         """Mengecek ketersediaan"""         for rec in self:             rec.availability = rec.student_per_room - len (rec.student_ids.ids)           availability = fields.Float(compute='_compute_check_availability',store=True,         string='Ketersediaan',help='Ketersediaan kamar pada asrama')       student_ids = fields.One2many('asrama.student','room_id','Daftar pelajar',         help='Pelajar-pelajar dalam room ini')       asrama_amenities_ids = fields.Many2many('asrama.amenities',         'asrama_amenities_rel','room_id','amenity_id',         string='Amenities', domain="[('active','=',True)]",         help='Pilih fasilitas room'     )       _sql_constraints = [('room_no_unique','unique(room_no)','Nomor room harus unik!')]       @api.constrains('rent_amount')     def _check_rent_amount(self):         """Constraint pada nilai negatif"""         if self.rent_amount < 0:             raise ValidationError(_('Nilai rental tidak boleh negatif'))

3. View asrama.room
   

   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

4. Menjalankan odoo-bin dengan mengupgrade modul
   
   

   

5. Tabel asrama_room
   

   

6. Tampilan
