         return $this->showall($user);
    }

protected function showall(Collection $collection, $code =  200){
    if ($collection ->isEmpty()) {
      return $this->successResponse(['data'->$collection],$code);
    }

    $transformer = $collection->first()->transformer;
    $collection = $this->sortData($collection, $transformer);
