我的代码中存在问题，我看不到它。代码：
路线
Route::resource("prices", "PriceController", ['except' => ['edit', 'update']]);
控制器
public function store(Request $request)
{
if ($request->ajax()) {
$user = User::findOrFail($request->input("user_id"));
$user->prices()->save(new Price());
$price = $user->prices()->latest()->first();

我正在阅读，而我发现的所有事情都是由于路线造成的最偶然的错误，但我认为这里的路线是正确的。

您正在发帖user：
var array_string = '{"user":' + user + ', ...
但是在寻找user_id：
$user = User::findOrFail($request->input("user_id"));
由于找不到匹配的用户，findOrFail throws a 404。
