使用 symfony 请求 2 个表的问题
problem with a request on 2 tables with symfony
我试图通过条令请求获取存储在 message_document table 中的消息的文档，但请求循环并最终填满了我的记忆
我在 Dbeaver 上用 sql 尝试了相同的请求，它运行没有问题
非常感谢您的帮助

'authorId' => $messageUnique->getUser()->getId(),
'content' => $messageUnique->getContent(),
'createdAt' => $messageUnique->getCreatedAt()
);
$allMessages->add($messageUnique);
}
我完全不确定如何将 $messageUnique = array() 设置为同一个变量的值，您可能应该使用另一个变量名称。如果你有一个无限循环问题，它来自你的 PHP。
我更改了我的代码，现在错误消息是关于循环引用的

我认为一切都在那里。
有点长抱歉...
希望有人能找到我有这个循环引用的原因
谢谢
我终于解决了问题:)
我在 MessageDocument 实体
的两个属性上使用了 @ignore 装饰器
我试图通过条令请求获取存储在 message_document table 中的消息的文档，但请求循环并最终填满了我的记忆 我在 Dbeaver 上用 sql 尝试了相同的请求，它运行没有问题

//$messageUnique->addMessageDocument($document);
}
$conversation->setLastMessage($messageUnique);
$messageUnique = array(
'id' => $messageUnique->getId(),
'author' => $messageUnique->getUser()->getFullName(),
'authorId' => $messageUnique->getUser()->getId(),
'content' => $messageUnique->getContent(),
'createdAt' => $messageUnique->getCreatedAt()
);
$allMessages->add($messageUnique);
}
我完全不确定如何将 $messageUnique = array() 设置为同一个变量的值，您可能应该使用另一个变量名称。如果你有一个无限循环问题，它来自你的 PHP。
我更改了我的代码，现在错误消息是关于循环引用的
