【问题描述】：
我正在使用nova-dependency-container，但收到以下错误Object of Class App\PageStatus could not be converted to 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...但是在尝试查看页面/资源时，我只是收到此错误并看到一个空白页面...
这是我的app/Nova/Page.php 模型

更新
pageStatus迁移文件：
class CreatePageStatusesTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('page_statuses', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('status')->index()->unique();
$table->string('label');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('page_statuses');
}
}
【问题讨论】：
-
检查迁移文件，可能有问题。检查mysql中列的类型。
-
我已经检查了一切，一切都是正确的。我也会添加迁移文件
-
只是猜测 - 它是函数 getIdByStatus($status)，从返回
return self::where('status', $status)->first();的末尾删除 id 并调整您的资源。 -
我发现了问题。我会回答我的问题。如果您有兴趣，请阅读。
