Hi !

I wrote an @api.onchange method (ation_afaire) that detects a change in a Datetime field and calls another method (action_confirm) of the same class which among other things changes the order status to 'sale'. Everything works fine, when I make a change in the date_realization field the order state changes to sale. The problem is that when I click on save the system doesn't pick up the change and it all goes back to the previous state !

Does anybody knows why I am being unable to save this state change ?

Thank you !

Here's the code:

# -*- coding: utf-8 -*-

from odoo import models, fields, api

class gescom_states(models.Model):

    _inherit = 'sale.order'

    date_realization= fields.Datetime(string='Date de réalisation', store=True)

@api.multi
    def action_confirm(self):
        for order in self:         
            order.state = 'sale'          
        if self.env.context.get('send_email'):
                self.force_quotation_send()
            order.order_line._action_procurement_create()
        if self.env['ir.values'].get_default('sale.config.settings', 'auto_done_setting'):
            self.action_done()          
        return True

    @api.onchange('date_realization')
    def action_afaire(self):
        super (gescom_states,self).action_confirm()
