How to implement eloquent 'saving' event for all models , not individually

Question

Based on documentation of laravel eloquent event, all the eloquent event are triggered individually based on each model, is there any way to use 'creating' event or any other eloquent event to be triggered by all the Models

For example , if any Models is created , event A is triggered

@AdamKozlowski no , i really mean about how to use laravel eloquent event globally to all model, right now in the documentation it's just show how to use it individually — Lejiend, Dec 06 '17 at 09:39

Listen for the Eloquent creating event that is fired. It is a 'string' event still not an object so you can do some ... wildcard matching here.

This is the string of the events that are fired from Eloquent:

"eloquent.{$event}: ".static::class

So you could listen for "eloquent.creating: *" to catch all those string events for Eloquent creating for any Model.

Event::listen('eloquent.creating: *', function ($event, $model) {
    ....
});

Obviously if you have defined your model to use custom event objects this would not be able to catch those.

You also could make a model observer, but you would have to register it to every model in your application you wanted to catch events for.

how about if i want to put an exception for a certain model ? — Lejiend, Dec 07 '17 at 08:53

Extend the model class:

use Auth;
use Illuminate\Database\Eloquent\Model;

class GeneralModel extends Model
{
  public static function boot()
  {
    parent::boot();

    static::creating(function ($model) {
        if (Auth::user()) {
            $model->created_by = Auth::user()->id;
            $model->updated_by = Auth::user()->id;
        }
    });
  }
}

When you say create a say property object, it will be triggered. Use it for all the models you need this.

class Property extends GeneralModel
{
  //..
}
