Laravel에서 모델 이벤트를 사용하는 방법에 대해 이야기해 보겠습니다.

declare(strict_types=1);

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;

class Office extends Model
{
    public static function boot(): void
    {
        static::creating(fn (Model $model) =>
            $model->uuid = Str::uuid(),
        );
    }
}

declare(strict_types=1);

namespace App\Models\Concerns;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;

trait HasUuid
{
    public static function bootHasUuid(): void
    {
        static::creating(fn (Model $model) =>
            $model->uuid = Str::uuid(),
        );
    }
}

declare(strict_types=1);

namespace App\Observers;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;

class OfficeObserver
{
    public function creating(Model $model): void
    {
        $model->uuid = Str::uuid();
    }
}

declare(strict_types=1);

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;

class Office extends Model
{
    protected $dispatchesEvents = [
        'creating' => SetModelUuid::class,
    ];
}

declare(strict_types=1);

namespace App\Models\Events;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;

class SetModelUuid
{
    public function __construct(Model $model)
    {
        $model->uuid = Str::uuid();
    }
}

declare(strict_types=1);

namespace App\Models\Pipelines;

use App\Models\Office

class OfficeCreatingPipeline
{
    public function __construct(Office $model)
    {
        app(Pipeline::class)
            ->send($model)
            ->through([
                ApplyUuidProperty::class,
                TapCreatedBy::class,
            ]);
    }
}
