保存實體原則/ symfony2的副本

Question

我想保留實體的以前版本。當「老」實體更新我想它使用相同的ID，但具有不同的版本號，所以它看起來是這樣的

ID保存：1 REVISION_NUMBER：1

ID ：1個REVISION_NUMBER：2

這是實體

有沒有辦法我可以做我描述的？

Answer 1

我想你可能需要的是Loggable extension for Doctrine。檢查此鏈接：

https://github.com/Atlantic18/DoctrineExtensions/blob/master/doc/loggable.md

可記錄的行爲跟蹤記錄更改，並能夠管理版本。

使用可記錄行爲，您可以使用revert()方法從存儲庫恢復版本。你可以在網站上找到很多例子，我給你上面的鏈接。

Answer 2

如果使用第三方捆綁此不花哨：

您的ID仍然必須是唯一的。如果您需要跟蹤副本的來源，那麼您可以添加一個新參數。

一旦你決定了這一點，我會簡單地克隆它，修改版本號，並添加原始ID，如果這是你想要去的方式，然後堅持它。

class Form { 
    // .... 
    $orig_id = null; 

    // any getters/setters you need 
    // ..... 
} 

然後控制器：

public function copyEntity($entity) { 
    $new_ent = clone $entity; 

    $new_ent->setOrigId($entity->getId()); 
    $new_ent->setRevision(true); // I would probably bin this as origId being !== null would do the same job 

    $this->entityManager->persist($new_ent); 
    $this->entityManager->flush(); 

    // ..... 


}
