php – 保存实体doctrine / symfony2的副本

我想保留以前版本的实体.当’旧’实体更新时,我想用相同的id保存它,但是使用不同的版本号,所以它看起来像这样

id：1 revision_number：1

id：1 revision_number：2

这是实体

有没有办法可以做我描述的事情？

解决方法:

我想你可能需要的是Loggable extension for Doctrine.检查这个链接：

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

Loggable behavior tracks your record changes and is able to manage versions.

使用loggable行为,您可以使用revert()方法从存储库中恢复版本.你可以在网站上找到很多例子我给你上面的链接.
