Php 类App\PageStatus（DateTime？）的对象无法转换为int

我正在使用，但遇到以下错误：类App\PageStatus的对象

无法转换为int

。在Laravel Nova中创建新页面/资源或尝试在Laravel Nova中查看页面/资源时，会出现此错误

但是，仍然会创建页面/资源。。。但是当我试图查看页面/资源时，我只是得到了这个错误，并看到一个空白页面

这是我的

更新

pageStatus

迁移文件：

class CreatePageStatusesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()

            $table->bigIncrements('id');
            $table->string('status')->index()->unique();
            $table->string('label');

     */

我发现了问题。我必须将

->dependsOn（'pageStatus'，pageStatus:：getIdByStatus（'future'））更改为
->dependsOn（'pageStatus.id'，pageStatus:：getIdByStatus（'future'））

缺少指定postStatus列的
.id
。
请检查迁移文件，可能有问题。检查mysql中列中的类型。我已经检查了所有内容，所有内容都是正确的。我将把迁移文件添加到just gusting中——它是函数getIdByStatus（$status），从return的末尾删除id
return self:：where（'status'，$status）->first（）并调整您的资源。我发现了问题。我会回答我的问题。如果你感兴趣，请仔细阅读。
