如何从内部控制器获得带有Symfony 2.1的Doctrine实体的实体管理器 [英] How to get entity manager for Doctrine entity with Symfony 2.1 from inside controller

问题描述

如何从控制器中获得最新的Symfony和Doctrine的实体经理？

How can I get an entity manager from inside a controller with latest Symfony and Doctrine?

现在标记为已弃用的The Book中描述的方式。什么是现代的（正确的）方法？

The way described in "The Book" flagged as deprecated now. What is a modern (proper) way to do this?

public function someAction()
{
    // getEntityManager() from Doctrine\Bundle\DoctrineBundle\Registry is deprecated
    $entityManager = $this->getDoctrine()->getEntityManager();
    ...
}

推荐答案

实际上，最好使用 $ this-> getDoctrine（） - > getManager（）服务层，以抽象数据的持久性。

Actually, it's best not to make controllers aware of the persistence layer you're using. That stuff should be moved to the Service Layer to abstract the way the data is persisted.
