php - 无法从 StudentController 更新功能更新学生数据

Question

我试图从数据库中更新学生数据，但更新数据时出现此错误。错误如下：

错误：

Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_RECOVERABLE_ERROR) 函数 App\Http\Controllers\StudentController::update() 的参数太少，通过了 1 个，预期正好有 2 个

public function store(Request $request)
{

    //Insert data into Student Table
    $student = new Student;
    $student->name = $request->name;
    $student->registration_id = $request->registration_id;
    $student->department_name = $request->department_name;
    $student->info = $request->info;
    $student->save();

    return redirect()->route('index');   
}

public function update(Request $request, $id)
{
    $student = Student::find($id);

    $student->name = $request->name;
    $student->registration_id = $request->registration_id;
    $student->department_name = $request->department_name;
    $student->info = $request->info;
    $student->save();

    return redirect()->route('index');
}[enter image description here][1]

我已经得到了我的问题的偿付能力，问题是我没有在路由函数中保留 ID，比如 ****Route::post('/update/{id}', 'StudentController@update')->name( '更新'）;****
