Laravel 5 : on success Validation Request function - laravel-5

Question

In laravel 5, we can now use the Request classes for input validation like so :
public function store(StoreItemRequest $request)
{
$item = Item::create($request->all());
return 'success';
}
When the validation fails, I can get the errors thanks to the response function in the Request class :
public function response(array $errors) {
return response()->json(['errors' => $errors]);
}
But what if the validation succeeds? Is there a function that would get automatically triggered like so :
public function ????(){
if($request->ajax())
return response()->json(['success' => true]);
}
Note: it is required that the content of the function store does NOT get executed if the request is ajax (just as it would not get executed if the validation fails).

Answer 1

Yeah, I found validate method in ValidateWhenResolvedTrait which you could override in your form request class;
public function validate(){
$instance = $this->getValidatorInstance();
if($this->passesAuthorization()){
$this->failedAuthorization();
}elseif(!$instance->passes()){
$this->failedValidation($instance);
}elseif( $instance->passes()){
if($this->ajax())
throw new HttpResponseException(response()->json(['success' => true]));
}
}

Answer 2

Currently there is no such method. You can do this in your request with some "hacks" (like override validate method) but I do not recommend it.
Idea of Request was to move validation/authorization out of controller. If you move successful response to Request than we have the same situation as before (well, name changed).
I would suggest to let controller handle ajax too:
public function store(StoreItemRequest $request)
{
$item = Item::create($request->all());
if($request->ajax())
return response()->json(['success' => true]);
return 'success';
}
Is there a reason why you are trying to achieve this in a request?
