// 1. Create an Observer: php artisan make:observer UserObserver --model=User

// app/Observers/UserObserver.php
namespace App\Observers;

use App\Models\User;

class UserObserver
{
    public function creating(User $user)
    {
        // Logic before a User is created
        $user->uuid = (string) \Illuminate\Support\Str::uuid();
    }

    public function created(User $user)
    {
        // Logic after a User is created
        \Log::info('User ' . $user->id . ' was created.');
    }

    public function updating(User $user)
    {
        // Logic before a User is updated
        // For example, preventing updates to certain fields
    }

    public function deleted(User $user)
    {
        // Logic after a User is deleted
        \Log::warning('User ' . $user->id . ' was deleted.');
        // Clean up related resources, e.g., delete profile image
    }
}

// 2. Register the Observer (e.g., in AppServiceProvider.php boot method)
// use App\Models\User;
// use App\Observers\UserObserver;
// User::observe(UserObserver::class);
