General model event listener

[lloricode]

Hi!

Is there a way to listen to all model event rather than creating observer to each model?

We have numerous models that needs to clear its cache in every update. Implementing listener or booting event to each model seems too tedious for us now.

Thank you!

Hi ✋🏻

You could try this:

1.- Create an observer to listen the Illuminate\Database\Eloquent\Model class, since all models inherit from this class.

<?php

namespace App\Observers;

use Illuminate\Database\Eloquent\Model as Eloquent;

class EloquentObserver
{
    /**
     * Handle the eloquent "created" event.
     *
     * @param  \App\Models\Eloquent  $eloquent
     * @return void
     */
    public function created(Eloquent $eloquent)
    {
        //
    }

    /**
     * Handle the eloquent "updated" event.
     *
     * @param  \App\Models\Eloquent  $eloquent
     * @return void
     */
    public function updated(Eloquent $eloquent)
    {
        //
    }

   // The rest of the observer's methods...
}

2.- Define this in the EventServiceProvider boot method.

    /**
     * Register any events for your application.
     *
     * @return void
     */
    public function boot()
    {
        // We can not instanciate Illuminate\Database\Eloquent\Model 
        // so we create a new instance of each model
        $models = [
            new \App\Models\User,
            new \App\Models\Post,
            // The rest of your models...
        ];

        collect($models)->each->observe(EloquentObserver::class);
    }

With this, any Model registered in the array, will have the same EloquentObserver assigned.
