Symfony2:即使存在对象，也要在非对象上调用成员函数 getId()? [英] Symfony2: Call to a member function getId() on a non-object even though there is an object?

问题描述

我不断收到此错误:

    /* ... */
    $em = $this->getDoctrine()->getEntityManager();
    $movie = $em->getRepository('MyMyBundle:Movie')->findMovieByName('moviename'); // Repository Class
    DoctrineCommonUtilDebug::dump($movie); // dumps the object just fine! The Repository found it
    echo $movie->getId(); // brings me the error nevertheless

致命错误:在...中的非对象上调用成员函数getId()在线...

Fatal error: Call to a member function getId() on a non-object in ... on line ...

我的实体中有 getId() 方法.即使它是和对象，其他方法也不起作用！

I have the getId() method in my Entity. Other methods also don't work even though it is and object!

对象被转储如下:

..... array(1) { [0]=> object(stdClass)#759 (59) { ["__CLASS__"]=> string( .....

有什么提示吗?

推荐答案

没关系，我找到了答案:echo $movie[0]->getId();(存储库返回一个数组对象).抱歉，有时您只见树木不见森林.

Nevermind, I found the answer: echo $movie[0]->getId(); (the repository returned an array of objects). Sorry, sometimes you lose sight of the wood for the trees.
