Doctrine 找不到目标实体

【中文标题】Doctrine 找不到目标实体【英文标题】:Doctrine The target-entity cannot be found in 【发布时间】:2017-09-23 00:56:42 【问题描述】:尝试加载我的网页时,我在服务器上收到此错误: 在“ArcaSolutions\ListingBundle\Entity\Listing#classified”中找不到目标实体 ArcaSolutions\ListingBundle\Entity\Classified。 我毫不怀疑问题在于目标实体引用的是 ListingBundle 而不是 ClassifiedBundle,但我在我的代码中看不到任何可能犯此错误的地方。
到目前为止,我已经尝试重新启动 Apache,并清除了学说缓存。
这是 Classified.php 的代码 (MyProject\src\ArcaSolutions\ClassifiedBundle\Entity\Classified.php)
namespace ArcaSolutions\ClassifiedBundle\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\ORM\Mapping\JoinColumn;
use JMS\Serializer\Annotation as Serializer;
/**

public function addListingArray(\ArcaSolutions\ListingBundle\Entity\Listing $listingArray)

【问题讨论】:
尝试删除列表中的classifiedId
,因为您不需要它,这可能会造成问题
你试过重启 Apache / php-fpm 吗?如果您启用了 apc 缓存,仅清除缓存文件夹是不够的。您还可以显示两个文件的完整文件名吗?
@kunicmarko20 删除分类 ID 没有影响,删除后仍然收到相同的错误。
@MaksymMoskvychev 我已经重新启动 Apache 以确保清除缓存,但仍然收到相同的错误。我还包括了 MyProject 根文件夹中的完整路径名。
它在错误的地方寻找你的实体 ArcaSolutions\ListingBundle\Entity\Classified
这个实体在 ClassifiedBundle
而不是 Listing
你是否清除了你的学说缓存?
【参考方案1】:
您的问题与这 2 个实体无关。 看,也许您在项目中有另一个具有相同命名空间的实体? (复制粘贴问题?)重构后可能会留下一些东西。
我用你的名字创建了 2 个包,用你的内容创建了 2 个实体,它工作得很好(索引除外,它是为不存在的字段定义的)。我能够生成有效的迁移,Doctrine 也说“0 个无效实体”:
CREATE TABLE Classified (id INT AUTO_INCREMENT NOT NULL, PRIMARY
KEY(id)) DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE =
InnoDB;
CREATE TABLE Listing (id INT AUTO_INCREMENT NOT NULL, classified_id
INT DEFAULT NULL, INDEX IDX_4BD7148A0B0417E (classified_id), PRIMARY
KEY(id)) DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE =
InnoDB;
ALTER TABLE Listing ADD CONSTRAINT FK_4BD7148A0B0417E FOREIGN KEY
(classified_id) REFERENCES Classified (id);
【讨论】:
Moskvychev 它必须是这两个实体,我可以注释掉 $classified 和 $listingArray 的私有声明,并且网页加载正常。 (即 //private $classified;)【参考方案2】:我设法通过将 $classified 重命名为 $theclassified、将 mappedBy="classified" 更改为 mappedBy="theclassified"、重新生成两个包并更新 db 架构来消除错误。我不确定这是如何修复错误的,因为我没有在其他任何地方引用 $classified ,所以这很奇怪。此外,我现在收到一个单独的错误,我将发布一个单独的问题。
