Provides a beautiful, simple ActiveRecord implementation for working with your database.

Eloquent Events

Allow you to easily execute code each time a specific model class is saved or updated in the database.


namespace App;

use App\Events\UserSaved;
use App\Events\UserDeleted;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
    use Notifiable;

     * The event map for the model.
     * @var array
    protected $dispatchesEvents = [
        'saved' => UserSaved::class,
        'deleted' => UserDeleted::class,

$flight = App\Flight::find(1);

// Retrieve the first model matching the query constraints...

$flights = App\Flight::find([1, 2, 3]);
