laravel project 404 error code example

Example 1: 404 json laravel

To do that, we need to add this logic to the app/Exceptions/Handler.php class:

use Illuminate\Database\Eloquent\ModelNotFoundException;

// ...

public function render($request, Exception $exception)
{
    if ($exception instanceof ModelNotFoundException && $request->wantsJson()) {
        return response()->json(['message' => 'Not Found!'], 404);
    }

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

Example 2: show 500 or 404 page in laravel

public function render($request, Exception $e)
{

    // 404 page when a model is not found
    if ($e instanceof ModelNotFoundException) {
        return response()->view('errors.404', [], 404);
    }

    if ($this->isHttpException($e)) {
        return $this->renderHttpException($e);
    } else {
        // Custom error 500 view on production
        if (app()->environment() == 'production') {
            return response()->view('errors.500', [], 500);
        }
        return parent::render($request, $e);
    }

}
