My post message(success) is showing perfectly and now i want to add error message to show if the attendance is not marked.


@http.route('/new_attendance_record', type='json', auth='user')
def new_attend_record(self, **rec):
    new_format = "%Y-%m-%d %H:%M:%S"
    local_tz = request.env.user.tz
    local_dt = pytz.timezone(local_tz)
    if request.jsonrequest:
        user = request.env.user
        mob_checkin = rec['check_in']
        # mob_checkout= rec['check_out']
        locate = rec['location']
        long = rec['longitude']
        lat = rec['latitude']
        print(long,lat,locate,'Hi')
        if mob_checkin:
            upd_checkin_time = datetime.strptime(mob_checkin, "%Y-%m-%dT%H:%M")
            local_dt1 = local_dt.localize(upd_checkin_time, is_dst=None)
            cin = local_dt1.astimezone(pytz.utc)
            mob_checkin = cin.strftime(new_format)
        # if mob_checkout:
        #     upd_checkout_time = datetime.strptime(mob_checkout, "%Y-%m-%dT%H:%M")
        #     local_dt2 = local_dt.localize(upd_checkout_time, is_dst=None)
        #     cout = local_dt2.astimezone(pytz.utc)
        #     mob_checkout = cout.strftime(new_format)
        print(mob_checkin)
        # print(mob_checkout)
        print(rec['location'])
        if user.id:
            vals = {
                # 'employee_id': user.id,
                'check_in': mob_checkin,

            }
            new_record = request.env['hr.attendance'].sudo().create(vals)
            if not new_record:
                return {'error': _('Unable to create attendance.')}
            else:
                args = {
                    'success': True, 'message': 'Mark Attendance successfully', 'id': new_record.id
                }
                return args
