我有一个控制器方法，我正在为我的实体 Order 创建一个插入方法，它与 User 实体有关系，一个用户可以有多个订单，现在当我创建订单并将用户设置为它，当我没有对其进行修改时，学说会尝试更新用户，我想知道我做错了什么 我的控制器方法

#[Route('/new', name: 'new', methods: ['POST'])]
    public function order(
        Request $request,
        ServiceRepository $serviceRepository,
        EntityManagerInterface $manager
    ): JsonResponse
    {
        $data = json_decode(json: $request->getContent());

        //get service
        if (!property_exists($data, 'service'))
            return $this->json(['status' => false, 'message' => 'service is required']);
        $service = $serviceRepository->find($data->service);

        $order = new Order();

        $order->setUser($this->getUser());
                $order->setCreatedAt(new \DateTimeImmutable());
        $order->setTotal(0);
        $order->setStatus(Order::STATUS_OPEN);
        $order->setService($service);

        $manager->persist($order);

    }

    public function addActivity(OrderItem $activity): self
    {
        if (!$this->activity->contains($activity)) {

所以我尝试保存订单，之后我使用订单 id 保存订单项是上面保存的订单，但它失败并给我 contstrain 错误 执行查询时发生异常： SQLSTATE[23000]: 完整性约束违规：1048 列“角色”不能为空 调试后发现，这里的doctrine是想更新我的用户，但是我对用户做了0修改，那为什么还要更新呢？
