MARKER常量覆盖Symfony2错误 [英] MARKER constant override Symfony2 error

问题描述

所以，我有一个类别实体设置，一个 parent_id 是自引用。但是由于某些原因，当我以表单保存条目时，我收到此错误。

So, I have a categories entity set up with a parent_id being self-references. But for some reason when I save the entry in the form I get this error.

Fatal error: Cannot inherit previously-inherited or override constant MARKER from interface Doctrine\Common\Persistence\Proxy in /var/www/html/project/vendor/doctrine/orm/lib/Doctrine/ORM/Proxy/Proxy.php on line 30

无法弄清楚它可能是什么。我根据教义文件设置了关系。

Can't figure out what it might be. I set the relationship up according to the Doctrine documentation.

/**
 * Set parent
 *
 * @param string $parent
 * @return Category
 */
public function setParent($parent)
{
    $this->parent = $parent;

    return $this;
}

/**
 * Get parent
 *
 * @return string 
 */
public function getParent()
{
    return $this->parent;
}

任何帮助将不胜感激。

推荐答案

显然这是 Doctrine-bundle 中的错误。将其更新到版本1.2。*（并随后更新相关软件包）修复了问题。

Apparently it was a bug in Doctrine-bundle. Updating it to version 1.2.* (and subsequently updating dependent packages) fixed the issue.
