Laravel mass update , still fire event - laravel

Question

As stated in the doc, laravel will not fire an event on mass update/insert/delete.
https://laravel.com/docs/5.8/eloquent#events
It uses the Builder for this and will not fire an event.
Is there a way that I can still fire an event after a mass update for example? I would only need the query Builder to extract the needed info myself ( log purposes).

It is actually possible , but you have to extend the Eloquent builder ,overwrite the update/insert methods and send the event there.
Just been playing around with it... Needs work, but the basic idea is the following :
class Test extends Model
{
protected $guarded = [];
public $dispatchesEvents = [
'saved' => SavedTest::class
];
/**
* INCLUDE this as a trait in your model.
* Overwrite the eloquentBuilder.
*
* #param \Illuminate\Database\Query\Builder $query
* #return \Illuminate\Database\Eloquent\Builder|static
*/
public function newEloquentBuilder($query)
{
return new TestBuilder($query);
}
}
Extend the eloquent builder...
class TestBuilder extends Builder
{
/**
* Update a record in the database and fire event.
*
* #param array $values
* #return int
*/
public function update(array $values)
{
// normal eloquent behavior.
$result =$this->toBase()->update($this->addUpdatedAtColumn($values));
/*
* Fire event.
*/
if($result){
if( $event = Arr::get($this->model->dispatchesEvents,'saved')){
// at the attributes.
$this->model->fill($this->addUpdatedAtColumn($values));
$queryBuilder =$this->toBase();
event(new $event($this->model,$queryBuilder));
}
}
}
public function insert(array $values)
{
// same idea..
}
}
The event class :
class SavedTest
{
use SerializesModels;
public $model;
public $query;
/**
* Create a new event instance.
*
* #return void
*/
public function __construct($model,$query =null)
{
$this->model = $model;
$this->query = $query;
}
}
The listener.
class SavedTestEvent
{
/**
* Create the event listener.
*
*
*/
public function __construct()
{
}
/**
* Handle the event.
*
* #param object $event
* #return void
*/
public function handle($event)
{
// The model , with the attributes.
dump($event->model);
// the query builder , you could extract the wheres or whatever to build your own log for it.
dump($event->query);
}
}

#Paolo on batch request it would not be file the event you must have to perform operation on single record.. like
Analytic::where('id', '>', 100)->get()->each(function($analytic) {
$analytic->delete();
});
