How to perform action globally when record get updated in laravel-CodePudding

Is that possible to run this job UpdateRateZone globally wheneven Consignment Model gets updated anywhere in the system?

One method is to use Observer but observer doesn't work when update multiple reccord at once like

Consignment::where('status',1)->update(['address'=>'This']);

Is there anything else we can do?

Yes you can create a Event Listener for your model. You can read up on more info here

In short first you need to create an Event for the needed model, so if its a Updated event create something like this.

php artisan make:event Consignment/Updated

In that file add

class Updated
{
use Dispatchable, InteractsWithSockets, SerializesModels;

 /**
 * @var Consignment
 */
public $consignment;

/**
 * Create a new event instance.
 *
 * @return void
 */
public function __construct(Consignment $consignment)
{
    $this->consignment= $consignment;
}

/**
 * Get the event consignment property
 *
 * @return Consignment
 */
public function getConsignment()
{
    return $this->consignment;
}
}

Now you must create a Listener for this event

php artisan make:listener Consignment/UpdatedEvent

And in the handle function add youre logic

/**
 * Handle the event.
 *
 * @param  Updated  $event
 * @return void
 */
public function handle(Updated $event)
{
    //
}

And all that is left after that is to register the events for you Model and you do that in your Consignment.php class where you add

/**
 * The event map for the category.
 *
 * @var array
 */
protected $dispatchesEvents = [
    'updated' => Updated::class,
];

As per laravel docs :

When issuing a mass update via Eloquent, the saving, saved, updating, and updated model events will not be fired for the updated models. This is because the models are never actually retrieved when issuing a mass update.

Laravel does not fire updated event in case of mass update, so its not possible as per my knowledge. Other way is to do manually.

Other than observers there is methods such using closures for events and Registering events manually but all these methods would work if only laravel trigger an event on mass updation .

When you do this:

Model::where('status',1)->update([some stuff]);

Query Builder's update() method is executed instead of Eloquent's update() method.

If you want to trigger Eloquent events, you need to update rows one by one. You can fire these events manually, but it's tricky and it's a bad idea.

You could just run the UpdateRateZone job manually for all the Consignments that were updated
