Laravel 5.2 - creating a model from a variable

Question

I am trying to access dynamically models so that I can get the count for each of them depending on which string I pass to the function. This is what my function in the controller looks like:

public function numberOf(Request $request){
    $modelName = $request['option'];
    $model = new $modelName;
    $data = $model->count();

    return json_encode($data);
  }

But when I pass a string, like in this case 'Article' I get an error:

Fatal error: Class 'Article' not found

Even though I am calling it in the controller:

use App\Article;

Yes, and it is working fine in the other function in the same controller when I am using Article model like this: $numberOfArticles = Article::count(); — Ludwig

I had to add App to model name, so that my function looks like this now and everything works fine now:

$modelName = 'App\\'.$request['option'];
$model = new $modelName;
$data = $model->count();

return json_encode($data);
