That's how you catch Exceptions (with try/catch)...

If you don't want the Exception, what do you want?

public function render($request, Throwable $e)
{
    if ($e instanceof \Illuminate\Database\Eloquent\ModelNotFoundException) {
        return Response::json([
            'message' => $e->getMessage(),
            'code' => $e->getCode(),
        ], $e->getCode());
    }

    return parent::render($request, $e);
}

@tykus No,I want to tackle this exception without using try catch block.


   $isUserCreate = User::findorFail(30);


        throw_if(!$isUserCreate, Exception::class, 'test', 404);

@Amrith you can handle the ModelNotFoundException in the app/Exceptions/Handler.php by implementing the render method like I have shown above.

Or, you don't use the findOrFail method:

$isUserCreate = User::find(30);
throw_unless($isUserCreate, // ...)

@tykus Thanks mate. here is my edited code , according to this code. how can i catch another exception. I want to handle all exception in global way. without using controller's try() catch{}

@tykus ,What is different beween renderable method vs render method

RegisterationController.php

 $isUserCreate = User::findorFail(30);

handler.php

 public function register()
    {

        $this->renderable(function (Exception $e, $request) {


            if ($request->wantsJson()) {
                return Response::json([
                    'myMessage' => $e->getMessage()
                ], $e->getStatusCode());
            }
        }

        );


    }

@Amrith there is no difference between the renderable Closure and the render method - both will allow you to define your own responses either for your own custom exceptions, or to intercept before the default render methods of built-in Exception classes.

If you're all set; please mark your thread(s) closed.
