    public function setModerated($moderated)
    {
        $this->isModerated = $moderated;

}

如你所见，我在照片中有isActive，这说明是否删除了照片。所以，我通过User-＆gt; getPhotos（）得到所有用户的照片，这是一对多的。但它返回所有用户的照片。该怎么做，所以它返回所有isActive = true的照片？

谢谢

Answer 1

您可以尝试使用过滤方法查询实体内部

$user->getPhotos()->filter(
    function($photo) {
       return $photo->isActive();
    }
); 

Answer 2

你可以使用@Cosmin Ordean的代码在User实体中创建一个方法:)像这样的东西

public function getActivePhotos() {
     return $this->getPhotos()->filter(
        function($photo) {
           return $photo->isActive();
        }
     );
}

Answer 3

有很多方法可以做到这一点。

Cosmin为您提供了一个，这将导致Doctrine加载每张照片，然后PHP代码检查以查看它是否处于活动状态。这将适用于大多数情况，但可能效率低下。

另一种解决方案是使用“标准”：

$exp = new \Doctrine\ORM\Query\Expr();
$activePhotos = $user->getPhotos()->matching(
    new \Doctrine\Common\Collections\Criteria(
        $exp->eq('active', true)
    )
);

这将执行与Cosmin建议的filter类似的操作，但允许Doctrine在数据库级别进行过滤。
