Symfony2插入错误“警告：spl_object_hash（）需要参数...”

时间：2015-05-12 00:25:16

标签： php symfony doctrine-orm doctrine

当我尝试保留我的对象并刷新它时，我收到此错误消息：

  

警告：spl_object_hash（）期望参数1为object，integer   给出500内部服务器错误 - ContextErrorException

我知道在堆栈溢出中已经发布了很多这样的问题，但它仍然无法解决我的问题。这就是为什么我在这里再问一次，希望有人可以帮助我。

以下是我保留用户类的代码： 

$package = $em->getRepository('MyBundle:Package')->findOneBy(array('id' => 1));
$new_user->addPackage($package);

$role = $em->getRepository('MyBundle:Role')->findOneBy(array('id' => 3));
$new_user->addRole($role);

$new_user->setCmsPrize(2); //int
$new_user->setCmsBet(3); //int
$new_user->setName("new user");
$new_user->setUserName("test123");
$new_user->setPassword("abc");
$new_user->setCreditLimit(1000);
$new_user->setCreditBalance(2000);
$new_user->setSelectedPackage($currentuser->getSelectedPackage());
$new_user->setParentId($currentuser->getId());
$new_user->setLayer($currentuser->getLayer() + 1);
$em->persist($new_user);
$em->flush();

以下是我的用户类：

错误日志：

  

CRITICAL - 未捕获的PHP异常   Symfony \ Component \ Debug \ Exception \ ContextErrorException：“警告：   spl_object_hash（）期望参数1是对象，给定“at”的整数   C：\ XAMPP \ htdocs中\项目\供应商\原则\ ORM \ LIB \原则\ ORM \ UnitOfWork.php   1389行

我能看到的另一件事是$ child，$ roles和$ packages变量的数据类型。它有什么不同吗？对于变量子，我没有设置任何东西，因为它不属于数据库的变量。它仅用于自引用，$ parent_id与此$ child具有自引用关系，所以我只设置$ parent_id。

我真的不知道，也许我对自我引用有错误的概念。

感谢您的帮助。

1 个答案:

答案 0 :(得分：5)

看一下注释，我的猜测是User :: setParentId（）期望一个User对象，而不是一个整数：

  /**
     * @ORM\ManyToOne(targetEntity="User", inversedBy="children")
     * @ORM\JoinColumn(name="parent_id", referencedColumnName="id", nullable=true)
     * 
     */

所以不要传递

$new_user->setParentId($currentuser->getId());

尝试：

$new_user->setParentId($currentuser);

如果可行，则应将字段名称适当更改为parent而不是parent_id。
