嵌套对象（来自DQL选择的混合结果） [英] Nested Objects (mixed results from DQL select)

问题描述

我有一个这样的doctrine2查询：

I have a doctrine2 query like this:

$query = $this -> doctrine -> em -> createQuery ("SELECT a, b FROM ORM\Dynasties2\Maillinks a JOIN a.msgId b");

它返回混合结果，类似于：

ORM\Dynasties2\Maillinks Object 
( 
    [id:ORM\Dynasties2\Millinks:private] => 1 
    [toUser:ORM\Dynasties2\Maillinks:private] => 16 
    [isRead:ORM\Dynasties2\Maillinks:private] => 0 
    [msgId:ORM\Dynasties2\Maillinks:private] => ORM\Dynasties2\Mailmsgs Object 
    ( 
        [id:ORM\Dynasties2\Mailmsgs:private] => 1 
        [msgText:ORM\Dynasties2\Mailmsgs:private] => asdfasdfasdfasdfasdfasdf 
        [fromUser:ORM\Dynasties2\Mailmsgs:private] => 13 
        [timeStamp:ORM\Dynasties2\Mailmsgs:private] => DateTime Object 
        (       
            [date] => 2012-04-20 12:17:29 
            [timezone_type] => 3 
            [timezone] => America/Los_Angeles 
        ) 
        [onTurn:ORM\Dynasties2\Mailmsgs:private] => 1 
        [importance:ORM\Dynasties2\Mailmsgs:private] => 2 
        [msgType:ORM\Dynasties2\Mailmsgs:private] => 1 
    ) 
)

我可以访问一些数据， 'top'很容易。

echo $ row - > getToUser（）; 返回'16'

I can access some of the data, at the 'top' easily enough.
echo $row -> getToUser(); returns '16'

我尝试过 echo $ row - > msgId-> getMsgText（）; ，但返回致命错误：无法访问私有属性ORM\Dynasties2\Maillinks :: $ msgId

如何访问对象内的数据？

或者：是我的查询和结果破碎？

Or: is my query and result broken? Do I need to do something different with my query or entities?

推荐答案

这是不是对你有用？

$row->getMsgId()->getMsgText();

你应该可以检查实际的实体文件（无论你有建造他们的原则还是其他人确定）检查该实体的getter和setter。

You should be able to check the actual entities files ( whether you had doctrine build them, or someone else did ) to check the getters and setters for that entity.
