如何从timestamp类型更改为datetime?

updated_at 是因为 datetime(3)

errors: "Trailing data"

因为Laravel需要timestamp类型而不是datetime。如何说larevel是datetime字段?

日志文件是:

[2019-06-02 14:41:07] local.ERROR: Trailing data {"userId":8,"exception":"[object] (InvalidArgumentException(code: 0): Trailing data atCarbon\\Traits\\Creator.php:537)
[stacktrace]
esbot\\carbon\\src\\Carbon\\Traits\\Creator.php(559): Carbon\\Carbon::rawCreateFromFormat('Y-m-d H:i:s', '2019-06-07 00:0...', NULL)

我试过了:

const UPDATED_AT = "AT_lastupdateuser";

protected $casts = [
    'AT_lastupdateuser' => 'datetime',
];
