事实上，我希望学会在Laravel上更新我的数据。我能够用记录中的信息恢复ID，但当我更改表单上的几个元素时，我会确认。
我有一个关于Illuminate\Routing\RouteCollection methodNotAllowed的问题，错误消息是Auth：：routes（）; route：：resource（'student'，'AdminController'）;
我的水平还慢，理解问题......我该怎么办？
这里是我的代码
我有一个名为AdminController的文件

class AdminController extends Controller
{
    public function index()
    {
      $students = Student::paginate(5);
      return view('student.index', compact('students'))
             ->with('i', (request()->input('page',1)-1)*5);
    }

    public function create()
    {
        return view('student.create');

    }

    public function store(Request $request)
    {
        $request->validate([
                'firstname' => 'required',
                'lastname' => 'required'
        ]);

        Student::create($request->all());
        return redirect()->route('student.index')
                    ->with('success', 'save');
    }

    public function edit($id)
    {
        $student = Student::find($id);
        return view('student.edit', compact('student'));

    }

    public function update(Request $request, $id)
    {
        $request->validate([
                'firstname' => 'required',
                'lastname' => 'required'
        ]);

        $student = Student::find($id);
        $student->firstname = $request->get('firstname');
        $student->lastname = $request->get('lastname');
        $student->save();

        return redirect()->route('student.index')
                  ->with('success', 'updated successfully');

    }

}

在视图中，我有一个名为Student的文件夹，其中包含2个文件

关于文件夹路线，我有，

Auth::routes();
route::resource('student','AdminController');

你有办法吗？因为我不明白我的问题...
