无法将表单数据绑定到学说查找功能。 "ORMInvalidArgumentException"

Question

我正试图在Symfony 4中制作一个简单的留言簿，我的目标是您可以向留言簿中添加一条消息，但在此之前，它需要内部激活我现在正在激活网站，但有一个问题我真的无法解决。错误消息如下：

将实体绑定到查询参数只允许具有标识符。

我想做的是，在您在ActivatorForm中键入未激活消息的ID后，它会从给定的表单获取数据(ID)，并且Doctrine会找到该ID的特定行。然后，它将smallint(非布尔值)"isActive">行更改为1，以便留言簿知道要显示哪些消息

在">$message=$repository->find($id)；">处，symfony无法将我的表单数据与查询参数绑定。我已经试过这个答案了，但也没用。

GBActivatorController.php：

use AppEntityGuestbook;
use SymfonyBundleFrameworkBundleControllerAbstractController;
use SymfonyComponentRoutingAnnotationRoute;
use SymfonyComponentHttpFoundationResponse;
use SymfonyComponentHttpFoundationRequest;
use SymfonyComponentFormExtensionCoreTypeTextType;
use SymfonyComponentFormExtensionCoreTypeNumberType;
use SymfonyComponentFormExtensionCoreTypeSubmitType;

class GBActivatorController extends AbstractController
{
public function index(Request $request)
{
//sets up the entity guestbook and the entitymanager from doctrine
$guestbook = new Guestbook();
$entityManager = $this->getDoctrine()->getManager();
//get all messages
$list = $this->getDoctrine()
->getRepository(Guestbook::class)
->findAll();
//create form for activating a non-activated message
$activator = $this->createFormBuilder($guestbook)
->add('id', NumberType::class,
array(
'mapped' => false,
))
->add('activate', SubmitType::class, ['label' => 'Activate'])
->getForm();
$activator->handleRequest($request);
/*when the submit button is clicked, get the data and
find the row with the specific id that was given.*/
if($activator->isSubmitted())
{
//gets the data from the form
$id = $activator->getData();
//sets up repository, so i dont need to type it again
$repository = $this->getDoctrine()->getRepository(Guestbook::class);
//(should) find the row
$message = $repository->find($id);
//activates row. (isActive = 1 instead of isActive = 0)
$message->setIsActive(1);
//persist and then execute to table
$entityManager->persist($message);
$entityManager->flush();
}
//renders the template
return $this->render('GBActivator.html.twig', array(
'list' => $list,
'activator' => $activator->createView()
));
}
}

谢谢Eakethet。我的问题是我需要一个数组而不是字符串。愚蠢的我，我换了

public function setId(Array $id)
{
$this->id = $id;
}

至

public function setId(string $id)
{
$this->id = $id;
}
