当我运行以下代码时，订单确实保存在数据库中。但在某些情况下id，保存的结果是。0在数据库中，Order 的正常 ID 为 100,101。

        $this->order->save(); // new order not in database yet
        //dd($this->order);

        $id = $this->order->id;
        if ($id === 0  || $id === null) {
            throw new CreateOrderFailedException('Order ID = null');
        }

上面的代码在 Homestead 沙盒上本地运行。当我将代码推送到暂存和生产环境时（它们都是 Vapor 环境）。保存函数总是返回一个$order->id我0 不知所措的原因。再次在本地工作。在会破坏这种情况的蒸汽环境中可能有什么不同？相同的 php 版本，相同的 laravel 版本。相同的（会话）缓存，相同的数据库。

这些dd语句在本地显示一个全新的 ID，但0在蒸汽（登台/生产）环境中。任何想法都会非常受欢迎。

我试过了：

  • $id = DB::table('orders')->insertGetId([atts])
  • $this->order = new Order([atts]); $this->order->save()
  • $this->order->create([atts])

结果保持不变（在本地完美运行，而不是在 Vapor 上部署一次）

编辑，做了一个非常肮脏的修复，现在解决了这个问题

        $id = DB::select('SELECT id FROM orders ORDER BY id DESC LIMIT 1');

        if ($id === null || $id[0]->id === 0) {
            throw new CreateOrderFailedException('Order ID = null');
        }

        $this->order->id = $id[0]->id;
        $this->addProductsToOrder($id[0]->id);
        $this->updateStatusAndCreateNote($id[0]->id);

因此，在没有 Model 类的情况下工作似乎可以正确检索最新的 ID。但是，如果有人可以详细说明这个 Eloquent 返回 id = 0 的问题，我会全力以赴。

根据要求dd放入保存功能的属性。

即使在这里，我也没有注意到任何实质性的东西，因为我已经在想了。我唯一的其他可能的解释是，蒸汽与数据库相关的一些事情是异步的。除此之外，我没有线索。
