Handling Race Conditions in Laravel Jobs and Queues

Use the withDefault() method to set a default related model when none exists:

   public function author()
   {
       return $this->belongsTo(User::class)->withDefault([
           'name' => 'Guest Author',
       ]);
   }

   Cache::remember('shared_data', 3600, function () {
       return [
           'max_uploads' => 10,
           'api_rate_limit' => 100,
           'features' => [
               'uploads_enabled' => true,
               'comments_enabled' => false,
           ],
       ];
   });

       App\Providers\CustomDataServiceProvider::class,
   ],

   php artisan make:provider SharedDataServiceProvider

Open the generated file in app/Providers/SharedDataServiceProvider.php and define a singleton for the shared data:
