تعديل بيانات الطالب

السلام عليكم ممكن حل مشكلة لدي كود تالي لتعديل بيانات 

Route::get('/student', [StudentController::class, 'index'])->name('/student');
Route::get('/student/create', [StudentController::class, 'create'])->name('/student/create');
Route::post('/student/create', [StudentController::class, 'store'])->name('/student/create');
Route::get('/students/{student}/edit', [StudentController::class, 'edit'])->name('students.edit');
Route::patch('/students/{student}/update', [StudentController::class, 'update'])->name('students.update');
