Doctrine 找不到目标实体

Question

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;

    */
    private $listingArray;

    /**

    */
    public function __construct()
    {
        $this->listingArray = new \Doctrine\Common\Collections\ArrayCollection();
    }

Answer 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);

Answer 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。
