我正在为我的项目使用 Laravel，我需要从记录、created_at->hour和created_at->minute的id生成no_track。我可以将数据保存到数据库，但在创建no_track后无法将数据保存到数据库。错误消息说：
array_key_exists((：第一个参数应该是字符串或 整数。
我附上了错误消息的图像。当我将数据保存到数据库时，我想从记录、小时和分钟的id获取no_track，并将no_track保存到no_track字段中。
我收到此错误消息

这是我的表结构：

在我的情况下，错误在以下行中：
$attrs = Attribute::get();
$attribute_ids = $attrs->map->only(['id']); // solved
而不是
$attrs = Attribute::get();
$attribute_ids = $attrs->get(['id']); // here was my error
我先替换
第二个不起作用
这是发生的错误
"message": "array_key_exists(): The first argument should be either a string or an integer", "exception": "ErrorException",
就我而言，代码中没有错误，然后我重新启动本地服务器，但没有任何反应我清除了我的缓存，视图，重新运行服务器，作曲家转储自动加载，但什么都不起作用。溶液
I terminate the current project server and run another project,
this project is run successfully, and after this I run my current project so it works like a charm.
