I want to add a popup that shows up when I use the "write" methode, the methode is called when the status of the status bar is changed:

from odoo import models, fields,api

from odoo.exceptions import ValidationError

import json

class labSample(models.Model):

_name = 'lab.sample'

_description = 'lab Sample (Base)'

name = fields.Char(string="Name", required=True)

sample_request_id = fields.Many2one('sample.request', string="Sample Request")

sample_request_line_id = fields.Many2one('sample.request.line', string="Sample Request Line", ondelete='cascade')

state= fields.Selection([

('draft', 'Draft'),

('progress', 'In progress'),

('done', 'Done'),

], string='Status', default='draft', required=True)

datum_test = fields.Date(string='Datum test')

uitvoerder = fields.Many2one('hr.employee', string='Uitvoerder')

required_for_done_fields = []

@api.constrains('state')

def _check_required_fields_on_done(self):

for record in self:

if record.state == 'done' and record.required_for_done_fields:

missing_fields = [

field for field in record.required_for_done_fields

if not getattr(record, field)

]

if missing_fields:

field_labels = ', '.join(self._fields[f].string for f in missing_fields)

raise ValidationError(

f"Je kan deze staal niet op 'Done' zetten zonder volgende ingevulde velden: {field_labels}."

)

def write(self, vals):

result = super().write(vals)

if 'state' in vals:

self._notify_success_message()

return result
