WithCast issues with Laravel Enum package?

[designvoid]

I have the following:

use App\Enums\BookingTypeEnum;
use Spatie\Enum\Laravel\Casts\EnumCast;
use Spatie\LaravelData\Attributes\WithCast;
use Spatie\LaravelData\Data;

class NewBookingData extends Data
{
    public function __construct(
        #[WithCast(EnumCast::class, class: BookingTypeEnum::class)]
        public BookingTypeEnum $type,
        public int $property_id,
    ) {
    }
}

and

use Spatie\Enum\Laravel\Enum;

/**
 * @method static self inventory()
 * @method static self inventoryCheckIn()
 */
final class BookingTypeEnum extends Enum
{
    protected static function labels(): array
    {
        return [
            'inventory' => 'Inventory',
            'inventoryCheckIn' => 'Inventory and Check-In',
        ];
    }
}

But when I call $newBooking = NewBookingData::from($request->validated());
It throws the following:

Spatie\LaravelData\Exceptions\CannotCreateCastAttribute
WithCast attribute needs a cast that implements `Spatie\LaravelData\Casts\Cast`

Hi @designvoid,

You're using a Eloquent cast, these types of casts are not compatible with the data package cast's. You can create your own EnumCast fairly quickly, more information about that over here: https://spatie.be/docs/laravel-data/v1/advanced-usage/creating-a-cast

Ok cheers - will give that shot!

there you go.

<?php

namespace Support\Casts;

use Spatie\Enum\Laravel\Enum;
use Spatie\LaravelData\Casts\Cast;
use Spatie\LaravelData\Casts\Uncastable;
use Spatie\LaravelData\Support\DataProperty;

class EnumCast implements Cast
{
    public function cast(
        DataProperty $property,
        mixed        $value
    ): Enum|Uncastable
    {
        $enum = $this->type ?? $this->findType($property);

        if ($enum === null) {
            return Uncastable::create();
        }

        return $enum::from($value);
    }

    protected function findType(
        DataProperty $property
    ): ?string
    {
        foreach ($property->types()->all() as $type) {
            if (is_a($type, Enum::class, true)) {
                return (string)$type;
            }
        }

        return null;
    }
}
