【问题描述】：

我的数据库中只有 1 行，当我将此代码放在我的 AnnouncementController 上时，我有一个 500 错误页面。

public function search(AnnouncesRepository $announcesRepository){

    $announces = $announcesRepository->findAll();

    return $this->render('announces/search.html.twig', ['announces' => $announces]);

}

仅当我使用 find($id) 或 findOne 时才有效。

感谢您的帮助！

编辑：

{% for announce in announces %} {{ dump(announce) }} {% endfor %}

我清除了缓存，是的，增加内存不是好主意，我只有 1 行！在我的模板中，我也尝试了转储宣布，但我有同样的错误。如果我删除转储，我有任何错误。

【问题讨论】：

Fatal Error: Allowed Memory Size of 134217728 Bytes Exhausted (CodeIgniter + XML-RPC)的可能重复
日志中的错误来自 twig -> 因此在您的 search.html.twig 内部 - 您可以进一步对公告执行 var_dump 以查看其中的真正内容吗？
增加内存限制不是个好主意，还有问题，他在表中只有一行
可能是模板中的无限循环？
在开发模式下运行您的应用程序并查看错误消息的内容。尝试在生产模式下调试应用程序充其量是具有挑战性的。顺便说一句，在生产中使用转储也是不行的。

【解决方案1】：

public function search(AnnouncesRepository $announcesRepository) {
    
    ini_set('memory_limit', '-1');

    $announces = $announcesRepository->findAll();

    return $this->render('announces/search.html.twig', ['announces' => $announces]);

}

或 php.ini -> memory_limit = 1024M
