how to check if update on model did succeed?

Hello kenjis,

> $this->db->affectedRows()
Undefined property: App\Controllers\CliController::$db

PHP Code:

File CLIController.php

$db = db_connect();
$JobModel_obj = new JobModel();

$UpdateResult = $JobModel_obj
                ->where('id', $JobFound['id'])
                //->where('status', JOB_STATUS_IDLE)
                ->where('status', 5)
                ->set(['status' => JOB_STATUS_STARTED])
                ->update();

echo "4=" . $db->affectedRows() . "\n"; 


shows 4=1 when no update has been done
