How to call a function with Request from under the controller?

Question

Laravel

Good afternoon, there is a function with which I get a list through Ajax

public function get(Request $request)
  {
    $lists = DB::table('lists')->where('user_id', $this->__user_id)->get();
    
    return json_encode($lists);
  }

How can I call this function from under the controller itself?

public function index()
  {
    $lists = $this->get();
    return view('lists', ['lists' => $lists]);
  }

Answer 1

pass null as an argument.
Better yet, move the shared code into another method, and then call it via get(); and through index();

Answer 2

Make a service (repository) User and pull it from anywhere

Answer 3

public function get(Request $request)
Remove Request $request , because you don't use it anywhere.
If used, take it in index() and pass the instance to the get function.
If it is not possible to receive it in index(), but it is required in get() - create a new instance of the Request class, fill it with the necessary or dummy data, and pass it.
A bunch of options. It all depends on the implementation and your code.
If the parts of the code in the question are not fictitious, but real, the first option will suit you. Remove Request.
