Laravel request validation throwing HttpResponseException in version 5.2 - php

Question

I'm trying to update Laravel from version 5.1 to 5.2 in my project, I have followed this upgrade guide from the documentation, but now I'm getting this HttpResponseException when a validation fails
* Handle a failed validation attempt.
*
* #param \Illuminate\Contracts\Validation\Validator $validator
* #return mixed
*
* #throws \Illuminate\Http\Exception\HttpResponseException
*/
protected function failedValidation(Validator $validator)
{
throw new HttpResponseException($this->response(
$this->formatErrors($validator)
));
}
In 5.1, the framework redirected to the previous url automatically with the validation errors.
This is my validation request
namespace domain\funcao\formRequest;
use autodoc\Http\Requests\Request;
class StoreFuncaoRequest extends Request
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'codigo' => 'required|max:255|unique:funcao,codigo,'.$this->input('id').',id,deleted_at,NULL',
'nome' => 'required|max:255|unique:funcao,nome,'.$this->input('id').',id,deleted_at,NULL'
];
}
}
I have already updated my Exceptions Handler according to the guide
class Handler extends ExceptionHandler
{
/**
* A list of the exception types that should not be reported.
*
* #var array
*/
protected $dontReport = [
\Illuminate\Auth\Access\AuthorizationException\AuthorizationException::class,
\Illuminate\Database\Eloquent\ModelNotFoundException::class,
\Illuminate\Foundation\ValidationException\ValidationException::class,
\Symfony\Component\HttpKernel\Exception\HttpException::class,
];
...
}
Did someone had this problem??

Answer 1

I found the cause for this error, I was calling PrettyPageHandler from Whoops manually in my Exception Handler class.
class Handler extends ExceptionHandler
{
/**
* A list of the exception types that should not be reported.
*
* #var array
*/
protected $dontReport = [
\Illuminate\Auth\Access\AuthorizationException\AuthorizationException::class,
\Illuminate\Database\Eloquent\ModelNotFoundException::class,
\Illuminate\Foundation\ValidationException\ValidationException::class,
\Symfony\Component\HttpKernel\Exception\HttpException::class,
];
...
/**
* Render an exception into an HTTP response.
*
* #param \Illuminate\Http\Request $request
* #param \Exception $e
* #return \Illuminate\Http\Response
*/
public function render($request, Exception $e)
{
// I just needed to remove this call to get rid of the problem
if (config('app.debug'))
{
return $this->renderExceptionWithWhoops($e);
}
return parent::render($request, $e);
}
/**
* Render an exception using Whoops.
*
* #param \Exception $e
* #return \Illuminate\Http\Response
*/
protected function renderExceptionWithWhoops(Exception $e)
{
$whoops = new \Whoops\Run;
$whoops->pushHandler(new \Whoops\Handler\PrettyPageHandler());
return new \Illuminate\Http\Response(
$whoops->handleException($e),
$e->getStatusCode(),
$e->getHeaders()
);
}
}
I'm still using Whoops, but now automatically through Laravel Exceptions

Answer 2

This was the first question I came across when I had this problem although for me it was with Sentry not Whoops.
Here's a couple of exceptions and how I dealt with them:
public function render($request, Exception $e)
{
if ($e instanceof TokenMismatchException) {
return redirect()->back()->withInput()->with('error', 'Your Session has Expired');
}
if ($e instanceof HttpResponseException) {
return $e->getResponse();
}
return response()->view('errors.500', [
'sentryID' => $this->sentryID,
], 500);
}
I handle the HttpResponseException by simply returning the response the same way the ExceptionHandler class does.

All you have to do is, just write your business logics inside the protected failedValidation() inside your custom FormRequest class like follows
use Illuminate\Http\Exceptions\HttpResponseException;
use Illuminate\Contracts\Validation\Validator;
/**
* [failedValidation [Overriding the event validator for custom error response]]
* #param Validator $validator [description]
* #return [object][object of various validation errors]
*/
public function failedValidation(Validator $validator) {
// write your business logic here otherwise it will give same old JSON response
throw new HttpResponseException(response()->json($validator->errors(), 422));
}
