def action_button_confirm(self, cr, uid, ids, context=None): assert len(ids) == 1, 'This option should only be used for a single id at a time.' wf_service = netsvc.LocalService('workflow') wf_service.trg_validate(uid, 'sale.order', ids[0], 'order_confirm', cr)

# redisplay the record as a sales order
view_ref = self.pool.get('ir.model.data').get_object_reference(cr, uid, 'sale', 'view_order_form')
view_id = view_ref and view_ref[1] or False,
return {
    'type': 'ir.actions.act_window',
    'name': _('Sales Order'),
