Pembuatan Button di Form pada Pemrograman Odoo ERP

Dalam menjalankan aplikasi berbasis web tentu kita akan melihat tombol-tombol untuk menjalankan suatu aktifitas. Demikian juga kita juga dapat menambahkan button dan aktifitasnya pada pemrograman pada lingkup Odoo.

Pembuatan button dan aktifitasnya pada pemrograman Odoo ERP adalah seperti pada penjelasan-penjelasan berikut ini

1. Mendefinisikan Aktifitas pada Model
   
   Kita masuk ke Virtualmin pada Webmin dan mengupdate model seperti pada gambar di atas.
   
2. Menambahkan button pada view
   
   Kita melanjutkan ke View bagian form dan melakukan penambahan button seperti pada gambar di atas.
   
3. Restart Odoo
   
   Karena kita mengubah model maka kita perlu melakukan restart Odoo seperti pada gambar di atas.
   
4. Upgrade modul
   
   Karena kita mengunah view maka kita perlu melakukan Upgrade aplikasi seperti pada gambar di atas.
   
5. Menggunakan form
   
   Kita kemudian masuk ke form dan mencoba tombol CANCEL seperti pada gambar di atas.
   
   
   Tampak property tersebut sudah pada stage CANCELLED.
   
6. Source code model estate_property.py

   from odoo import api, fields, models
   
   class EstateProperty(models.Model):
   	_name = "estate.property"
   	_description = "Real Estate Property"
   
   	active = fields.Boolean(default=True)
   	state = fields.Selection(
       	[ 
           	('n', 'New'),
           	('o', 'Offer Received'),
           	('a', 'Offer Accepted'),
           	('s', 'Sold'),('c', 'Cancelled'),
           ],
       	'State', default='n'
       )
   
   	name = fields.Char(required=True,default='Rumah Baru')
   	description = fields.Text()
   
   	property_type_id = fields.Many2one("estate.property.type", string="Property Type")
   	tags_id = fields.Many2many("estate.property.tag", string="Property Tags")
   
   	postcode = fields.Char()
   	date_availability = fields.Date(copy=False)
   	expected_price = fields.Float()
   	selling_price = fields.Float(readonly=True,copy=False)
   	bedrooms = fields.Integer(default=2)
   	living_area = fields.Integer()
   	facades = fields.Integer()
   	garage = fields.Boolean()
   	garden = fields.Boolean()
   	garden_area = fields.Integer()
   	garden_orientation = fields.Selection(
       	[ 
           	('n', 'North'),
           	('s', 'South'),
           	('e', 'East'),
           	('w', 'West'),
           ],
       	'Garden Orientation', default='e'
   	)
   
   	user_id = fields.Many2one("res.users", string="Salesman",default=lambda self: self.env.user)
   	buyer_id = fields.Many2one("res.partner", string="Buyer",copy=False)
   
   	offer_ids = fields.One2many("estate.property.offer", "property_id", string="Offer")
   
   	best_price = fields.Float("Best Offer", compute="_compute_best_price", help="Best offer received")
   
   	@api.depends("offer_ids.price")
   	def _compute_best_price(self):
   		for prop in self:
   			prop.best_price = max(prop.offer_ids.mapped("price")) if prop.offer_ids else 0.0
   
   	@api.onchange("garden")
   	def _onchange_garden(self):
   		if self.garden:
   			self.garden_area = 10
   			self.garden_orientation = "n"
   		else:
   			self.garden_area = 0
   			self.garden_orientation = False
   
   	def action_sold(self):
   		if "c" in self.mapped("state"):
   			raise UserError("Canceled properties cannot be sold.")
   		return self.write({"state": "s"})
   
   	def action_cancel(self):
   		if "s" in self.mapped("state"):
   			raise UserError("Sold properties cannot be canceled.")
   		return self.write({"state": "c"})
