Hello Manoj,

You can try this

return {
    'warning': {
        'title': 'Warning!',
        'message': 'Your warning text here.'}
}

Regards

Hi, I have the same problem, and I used the following format in my code, but it does not display any message:

I want to display a warning message on a custom button (btc_approved) in sale.order.

I don't know what the issue is!

I understand this method is typically used under the onchange decorator, but I don’t have a field to use with onchange. Is there any alternative solution?

Here is my method:

def btc_approved(self):
    for record in self:
        user = record.user_id
        if record.b2c_status != 'ready':
            raise ValidationError(_("Only B2C Sale Orders with Ready can be Approved"))
        elif record.b2c_sales == False:
            raise ValidationError(_("Only B2C Sale Orders can be Approved"))
        else:
            if user.has_group('vatanzarin_security.visitor_group') and record.b2c_status == 'ready':
                partner =  record.partner_id
                if partner.sale_warn and partner.sale_warn_msg != 'no_message':
                    return {
                        'warning': {
                            'title': _("There is a warning note for %s") % partner.name,
                            'message': partner.sale_warn_msg,
                            'type': 'notification',
                        }
                    }
                record.b2c_status = 'approved'
                record.financial_status = 'approved'
                record.sudo().trigger_picking_atv(True)

Hi

You can use ValidationError or Usererrors  to display warning messages

from odoo.exceptions import ValidationError, UserError


def action_confirm(self):
    if (apply the condition):
        raise UserError(_('Warning Message'))
