Laravel - Mutators / Casts - Castables

You may want to allow your application's value objects to define their own custom cast classes. Instead of attaching the custom cast class to your model, you may alternatively attach a value object class that implements the Illuminate\Contracts\Database\Eloquent\Castable interface:

    
    use App\Models\Address;
    
    protected $casts = [
        'address' => Address::class,
    ];

Objects that implement the Castable interface must define a castUsing method that returns the class name of the custom caster class that is responsible for casting to and from the Castable class:



    When using Castable classes, you may still provide arguments in the $casts definition. The arguments will be passed to the castUsing method:

    
    use App\Models\Address;
    
    protected $casts = [
        'address' => Address::class.':argument',
    ];
