property attributes not working (validator, cast, etc.)?

[wivaku]

I am having trouble getting any (PHP 8) attributes to work.
Using Laravel v10, Spatie Laravel Data v3.4.3, PHP v8.2.

E.g.

class UserData extends Data
{
    public function __construct(
        #[Max(5)]
        public string $name,

        #[WithCast(DateTimeInterfaceCast::class, format: 'Y-m-d')]
        public ?CarbonImmutable $date,

        #[MapInputName('createdAt')]
        public CarbonImmutable $created_at,
    ) {
    }
}

$user = [
    'name' => 'John Doe',
    'date' => '1972-11-05',
    'createdAt' => now()->toAtomString(), // in DTO: created_at
];

$dto = App\Data\UserData::from($user);

gives error for date (and not for name)

Spatie\LaravelData\Exceptions\CannotCastDate �Could not cast date `1972-11-05` into a `Carbon\CarbonImmutable` using formats: Y-m-d\TH:i:sP.

So, the attributes (the cast, but also validation and mapinputname) are ignored?
(For the date attribute, the alternative works fine: add to data.php: 'date_format' => [DATE_ATOM, 'Y-m-d'],).

When adding ReflectionClass to the constructor, I do see the attributes for each of the properties.

  +name: "__construct"
  +class: "App\Data\UserData"
  parameters: {▼
    $name: ReflectionParameter {#1463 ▼
      +name: "name"
      position: 0
      allowsNull: true
      attributes: array:1 [▼
        0 => ReflectionAttribute {#1476 ▼
          name: "App\Data\Max"
          arguments: array:1 [▼
            0 => 5
          ]
        }
      ]
      typeHint: "string"
    }
    $date: ReflectionParameter {#1462 ▼
      +name: "date"
      position: 1
      attributes: array:1 [▼
        0 => ReflectionAttribute {#1475 ▼
          name: "App\Data\WithCast"
          arguments: array:2 [▼
            0 => "App\Data\DateTimeInterfaceCast"
            "format" => "Y-m-d"
          ]
        }
      ]
      typeHint: "string"
    },
    $created_at: ReflectionParameter {#1462 ▼
      +name: "created_at"
      position: 1
      allowsNull: true
      attributes: array:1 [▼
        0 => ReflectionAttribute {#1475 ▼
          name: "App\Data\MapInputName"
          arguments: array:1 [▼
            0 => "createdAt"
          ]
        }
      ]
      typeHint: "Carbon\CarbonImmutable"
    }
  }

From another discussion (#357) I understand I should be using validateAndCreate since from will only validate when a request has been passed on to it. I agree with the original poster: quite confusing. Maybe mention that when validations are first mentioned in the quick start and not only in the "from a request" section?

More importantly:

1. from should still handle the WithCast and MapInputName attributes, right?
2. with validateAndCreate I still get the same result

UserData::getValidationRules($user) does not show the Max(5) restriction:

[
  ["name" => ["required", "string"],
  ["date" => ["nullable"],
  ["created_at" => ["nullable"],
]

I can manually overwrite the rules which works fine (for the validation):

    public static function rules(): array
    {
        return [
            'name' => ['required', 'string', 'max:5'],
        ];
    }

But it will still not recognise the WithCast and MapInputName attributes

It was not clear from the documentation that Attributes are classes that need to imported...

use Spatie\LaravelData\Attributes\MapInputName;
use Spatie\LaravelData\Attributes\WithCast;
use Spatie\LaravelData\Attributes\Validation\Max;
use Spatie\LaravelData\Casts\DateTimeInterfaceCast;
// etc.
