Odoo 10 : Call a confirmation form (Yes / No) from Wizard

Question

I want to add to my purchase order a \'cancel\' button. This button will change the state of my record to \'canceled\'. When the user click on this button the script verify

Answer 1

Well, this is what I wrote :

    @api.multi
    def yes(self):
        print 'yes function'
        self.env['tjara.purchase_order'].function1()

    @api.multi
    def no(self):
        print 'no function'
        self.env['purchase_order'].function1()

The 'canceled_progressbar' method return :

    @api.multi
    def canceled_progressbar(self):
        print 'canceled_progressbar'
        return {
            'name': 'Are you sure?',
            'type': 'ir.actions.act_window',
            'res_model': 'tjara.confirm_wizard',
            'view_mode': 'form',
            'view_type': 'form',
            'target': 'new',
        }

And I added two function according to the confirmation :

    @api.multi
    def function1(self):
        print 'this function 1'

    @api.multi
    def function2(self):
        print 'this function 2'

I was wondering if I can make only one function but it seems like impossible.

Thank you all for helping.
