How do you handle exceptions when using firstOrFail with relationships

1. Try-Catch Block:
- Wrap the `firstOrFail()` call in a `try-catch` block to handle the `ModelNotFoundException` that may be thrown if no matching record is found.
- Example:

php
     try {
         $post = Post::with('comments')->whereHas('comments', function ($query) {
             $query->where('content', 'like', 'foo%');
         })->firstOrFail();
         
         $firstComment = $post->comments->firstOrFail();
     } catch (\Illuminate\Database\Eloquent\ModelNotFoundException $e) {
         // Handle the exception, e.g., return a 404 response
         return response()->json(['error' => 'Resource not found'], 404);
     }
     

2. Handling Exceptions in the `render()` Method:
- Override the `render()` method in the `App\Exceptions\Handler` class to handle the `ModelNotFoundException` exception globally.
- Example:

php
     public function render($request, Throwable $exception)
     {
         if ($exception instanceof \Illuminate\Database\Eloquent\ModelNotFoundException) {
             return response()->json(['error' => 'Resource not found'], 404);
         }
     
         return parent::render($request, $exception);
     }
     

3. Handling Exceptions in the Model:
- You can override the `findOrFail()` method in your model to provide a custom exception message.
- Example:

php
     public static function findOrFail($id, $columns = ['*'])
     {
         try {
             return static::findOrNew($id, $columns)->firstOrFail();
         } catch (\Illuminate\Database\Eloquent\ModelNotFoundException $e) {
             throw new \Illuminate\Database\Eloquent\ModelNotFoundException(
                 'The requested ' . static::class . ' resource was not found.'
             );
         }
     }
     

Regardless of the approach you choose, the key is to handle the `ModelNotFoundException` exception gracefully and provide a meaningful response to the user or client. This ensures that your application handles missing resources appropriately and provides a better user experience.
