Question

我在尝试加载网页时在服务器上收到此错误：目标实体ArcaSolutions \ ListingBundle \ Entity \ Classified无法在＆＃39; ArcaSolutions \ ListingBundle \ Entity \ Listing＃classified＆＃39;中找到。我毫不怀疑问题是目标实体引用的是ListingBundle而不是ClassifiedBundle，但是我在代码中的任何地方都看不到我可能犯过这个错误。

到目前为止，我已经尝试重新启动Apache，并清除了doctrine缓存。

以下是Classified.php的代码（MyProject \ src \ ArcaSolutions \ ClassifiedBundle \ Entity \ Classified.php）

Answer 1

您的问题与这两个实体无关。看，也许你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。

我创建了2个包含您的名称的包，2个包含您的内容的实体，它工作得很好（索引除外，它们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个无效的实体”：

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来改变错误，更改mappedBy =＆＃34;已分类＆＃34; to mappedBy =＆＃34; theclassified＆＃34;，重新生成两个包并更新数据库模式。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。
