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
   

   from datetime import datetime, timedelta
   from odoo import  _, fields, models, api
   from odoo.exceptions import UserError
   
   class AsramaStudent(models.Model):
       _name = 'asrama.student'
       _description = 'Informasi Asrama Student'
       partner_id = fields.Many2one('res.partner', ondelete='cascade', delegate=True)
   
       #name = fields.Char('Nama pelajar')
       gender = fields.Selection(
           [('male','Male'),('female','Female'),('other','Other')],
           string='Jenis kelamin',
           help='Jenis kelamin pelajar',
       )
       active = fields.Boolean('Active',default=True,help='Activate/Deactive record')
   
       room_id = fields.Many2one('asrama.room','Room',help='Pilih room')
       hostel_id = fields.Many2one('asrama.hostel',related='room_id.hostel_id')
       
       status = fields.Selection(
           [('draft','Draft'),('reservation','Reservation'),('pending','Pending'),('paid','Paid'),('discharge','Discharge'),('cancel','Cancel')],
           string='Status',copy=False,default='draft',
           help='Status asrama student'
       )
   
       @api.depends('admission_date','discharge_date')
       
       def _compute_check_duration(self):
           """Mengecek durasi"""
           for rec in self:
               if rec.discharge_date and rec.admission_date:
                   rec.duration = (rec.discharge_date - rec.admission_date).days
   
       def _inverse_duration(self):
           for stu in self:
               if stu.discharge_date and stu.admission_date:

                   if duration != stu.duration:
                       stu.discharge_date = (stu.admission_date + timedelta(days=stu.duration)).strftime('%Y-%m-%d')
                       
       admission_date = fields.Date('Tanggal masuk',help='Tangga di mana pelajar masuk asrama',
           default=fields.Datetime.today())
   
       discharge_date = fields.Date('Tanggal keluar',help='Tanggal di mana pelajar keluar asrama')
   
   #    duration = fields.Integer('Durasi', compute='_compute_check_duration',inverse='_inverse_duration',
   #        help='Durasi lamanya tinggal')
   
       duration = fields.Integer('Durasi', inverse='_inverse_duration',
           help='Durasi lamanya tinggal')
   
       def action_assign_room(self):
           self.ensure_one()
           if self.status != 'paid':
               raise UserError(_("Tidak bisa memberikan room jika belum Paid!"))
           room_as_super_user = self.env['asrama.room'].sudo()
           room_rec = room_as_super_user.create({
               'name': 'Kamar A-505',
               'room_no': 'A-505',
               'floor_no': 1,
               'student_per_room' : 5,

               'hostel_id': self.hostel_id.id,
           })
   
           if room_rec:
               self.sudo().room_id = room_rec.id
           
       def action_wizard_assign_room(self):
           return {
               'type' : 'ir.actions.act_window',

           if self.env.context.get('is_hostel_room'):
               self.room_id = False
   
       @api.onchange('admission_date','discharge_date')
       def onchange_duration(self):
           if self.discharge_date and self.admission_date:
               self.duration = (self.discharge_date - self.admission_date).days
   

3. Start Odoo dengan upgrade modul
   
   

   

4. Tampilan yang dihasilkan
