Abstract Model untuk Fitur yang Banyak Digunakan pada Odoo 17

Dalam melakukan pemrograman kita mungkin mendapati suatu fitur yang banyak digunakan di banyak tempat. Akan tidak efisien jika kita menulis code yang sama di berbagai tempat. Untuk kita kita dapat menggunakan abstract model.

Abstract model untuk fitur yang banyak digunakan pada Odoo 17 adalah seperti pada conroh berikut ini

1. Stat SSH filesystem
   

   

2. Model base.archive dan  asrama.room
   

   from odoo import fields, models, api, _
   from odoo.exceptions import ValidationError
   
   class BaseArchive(models.AbstractModel):
   	_name = 'base.archive'
   	active = fields.Boolean(default=True)
   	
   	def do_archive(self):
   		for record in self:
   			record.active = not record.active
   
   class AsramaRoom(models.Model):
       _name = 'asrama.room'
       _inherit = ['base.archive']
       _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
