如何将自动生成的输入传递给 laravel 中的 api 函数

Question

我有一个网络系统，输入字段会自动生成并保存在数据库中。我想将输入数据推送到 API 函数，并且能够推送一些输入。我有自动生成的输入字段，但无法推送它这是生成它的代码。

  $SystemID        = new SystemID('product');
  //the new SystemID('product'); autogenerates the the systemid which is saved in the product table
  $product         = new product();
  $product->systemid = $SystemID;
  $product->save();

我已经在控制器的 api 函数中尝试过此代码，但它显示错误 systemid 不能为 null

$productdetails=new Product;
$productdetails->systemid =$request->systemid;

我也有一个 SystemID 类其他 API 端点 Web 系统。 如何将自动生成的 systemid 传递给 api 中的控制器？

on dd(系统ID);我明白了

你必须先保存SystemID，这里你只创建了一个对象SystemID，所以它没有id。

  $SystemID        = new SystemID('product');
  $SystemID->save();
  $product         = new product();
  $product->systemid = $SystemID;
  $product->save();
