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/资源时或尝试在Laravel Nova中查看页面/资源时，会出现此错误。
但是，页面/资源仍然被创建...但是当尝试查看页面/资源时，我只是遇到此错误并看到空白页面...
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');
}
}
解决方法
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.id来指定postStatus的列。
