Symfony - '' 类型的预期值改为“字符串”

Question

我正在尝试将 id 从一个编队表传递到票证表，但我无法传递此错误..关联字段“App\Entity\Ticket#$formation”的“App\Entity\Formation”类型的预期值，取而代之的是“string”。组建实体：/** * @ORM\Entity(repositoryClass="App\Repository\FormationRepository") */class Formation{    /**     * @ORM\Id()     * @ORM\GeneratedValue()     * @ORM\Column(type="integer")     */    private $id;    /**     * @ORM\Column(type="array", nullable=true)     */    private $formations = [];    /**     * @ORM\Column(type="string", length=180, unique=true)     */    private $customerName;...票务实体：/** * @ORM\MappedSuperclass() */class Ticket implements TicketInterface{    use Timestampable;    /**     * @var integer     *     * @ORM\Column(name="id", type="integer")     * @ORM\Id     * @ORM\GeneratedValue(strategy="IDENTITY")     */    private $id;    /**     * @ORM\ManyToOne(targetEntity="Symfony\Component\Security\Core\User\UserInterface")     * @ORM\JoinColumn(name="author", referencedColumnName="id", nullable=true)     */    private $author;    /**     * @ORM\ManyToOne(targetEntity="App\Entity\Formation")     * @ORM\JoinColumn(nullable=false)     */    private $formation;...我的ticketControlleraddTicket()：public function addTicket(Request $request, TicketManager $ticketManager): Response{    $ticket = $ticketManager->newClass();    $user = $this->getUser();    $formationId = $user->getFormationId()->getId();    $ticketForm = $this->createForm(TicketForm::class, $ticket);    $ticketForm->handleRequest($request);    if ($ticketForm->isSubmitted() && $ticketForm->isValid()) {        $ticketManager->createTicket($user, $ticket, $formationId);        $this->addFlash('success', 'Le ticket est en ligne !');        return $this->redirectToRoute('ticketing_list');    }    return $this->render($this->ticketingTemplates['new'], [        'form' => $ticketForm->createView(),    ]);}我希望在添加票证时，将“formationId”保存在票证表中。其余的都很好，只有formulaId的注册不行

/**

 * @param UserInterface $user

 * @param TicketInterface $ticket

 * @throws \Doctrine\ORM\ORMException

 * @throws \Doctrine\ORM\OptimisticLockException

 */

public function createTicket(UserInterface $user, TicketInterface $ticket, Formation $formation)

{

    $status = $this->ticketStatusManager->getOpenStatus();

    $ticket->setStatus($status)->setFormation($formation)->setAuthor($user)->setPublic(false);

    if (!$this->isTicketRestrictionEnabled()) {

        $ticket->setPublicAt(new \DateTime())->setPublic(true);

    }

    $this->persistAndFlush($ticket);

}
