How to get parameter from url in laravel?

Question

Laravel

There is a route:

Route::resource('/home/staff_doctor/patient/{patient}/passport', 'PassportController');

There is a link:

<a href="{{route('passport.index', ['id' => $patient->id])}}"
                       class="btn btn-success btn-xs">Добавить паспорт</a>

There is a controller:

public function index($id)
    {
        $patient = Patient::find($id);
        return view(route('passport.index'), compact('patient'));
    }

How to make controller accept value from url?
/home/staff_doctor/patient/ 3 /passport
SOLUTION
Corrected the link:

<a href="{{route('passport.create', ['patient' => $patient->id])}}"
                       class="btn btn-success btn-xs">Добавить паспорт</a>
                    <a href="{{route('passport.index', ['patient' => $patient->id])}}"
                       class="btn btn-primary btn-xs">Посмотреть все</a>

Added a request in the index function in the controller:

public function index(Request $request)
    {
        $patient = Patient::find($request->patient);
        return view(route('passport.index'), compact('patient'));
    }
