Doctrine2:未定义索引

Question

当我尝试执行这个DQL查询时：

SELECT r, s FROM Rule r
JOIN r.splash_page s
WHERE r.active = 1

我想要做的就是加入两个实体，然后我得到了一个错误：

Notice: Undefined index: rules in C:\xampp\htdocs\excap\vendor\doctrine\orm\lib\Doctrine\ORM\Internal\Hydration\ObjectHydrator.php on line 110
Notice: Undefined index: rules in C:\xampp\htdocs\excap\vendor\doctrine\orm\lib\Doctrine\ORM\Internal\Hydration\ObjectHydrator.php on line 428
Notice: Undefined index: rules in C:\xampp\htdocs\excap\vendor\doctrine\orm\lib\Doctrine\ORM\Internal\Hydration\ObjectHydrator.php on line 428
Notice: Undefined index: rules in C:\xampp\htdocs\excap\vendor\doctrine\orm\lib\Doctrine\ORM\Internal\Hydration\ObjectHydrator.php on line 428
Notice: Undefined index: rules in C:\xampp\htdocs\excap\vendor\doctrine\orm\lib\Doctrine\ORM\Internal\Hydration\ObjectHydrator.php on line 428

这些是我的实体文件的一部分，我在其中声明了它们之间的关系：

// Rule.php 
/**
 *
 * @var type 
 * @ManyToOne(targetEntity="SplashPage", inversedBy="rules")
 */
protected $splash_page;

// SplashPage.php
/**
 *
 * @var type
 * OneToMany(targetEntity="Rule", mappedBy="splash_page") 
 */
protected $rules = null;

知道为什么会这样吗？

在您的$rules文档块中有一个错误:您在OneToMany之前忘记了@符号

文档块应该是：

/**
 * @OneToMany(targetEntity="Rule", mappedBy="splash_page") 
 */
protected $rules = null;

而不是

/**
 * OneToMany(targetEntity="Rule", mappedBy="splash_page") 
 */
protected $rules = null;
