我正在尝试在我的关系ManyToOne中保存我的ID,但是返回了一个错误:
这就是我试图保存数据的方式:
$user = $this->getUser()->getId();
$catalogcomment = new CatalogComment();
$form = $this->createForm(CatalogCommentType::class, $catalogcomment);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$catalogcomment->setUserId($user);
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($catalogcomment);
$entityManager->flush();
return $this->redirectToRoute('catalog_index');
}
这是与关系user_id相关的我的Entity CatalogComment
public function getUserId(): ?User
{
return $this->user_id;
}
public function setUserId(?User $user_id): self
{
$this->user_id = $user_id;
return $this;
}
收到的错误是:
传递给App \ Entity \ CatalogComment :: setUserId()的参数1必须是App \ Entity \ User的实例或null,int给出
我做错了什么?
谢谢你的时间。
我认为你必须调整实体CatalogComment中的映射关系,不要有属性$ userId,而是属性$ user,应该是User类型
class CatalogComment
{
// ...
/**
* @ManyToOne(targetEntity="User")
* @JoinColumn(name="user_id", referencedColumnName="id")
*/
private $user;
}
您还必须为$ user创建getter和setter,然后您可以在CatalogComment对象中设置用户,如下所示
$user = $this->getUser();
$catalogComment = new CatalogComment();
$catalogComment->setUser($user);
$em = $this->getDoctrine()->getManager();
$em->persist($catalogComment);
$em->flush();
希望能帮助到你 :)
