如何在Symfony2项目中配置扩展PersistentObject的Doctrine2实体? [英] How do I configure a Doctrine2 entity which extends PersistentObject within Symfony2 project?
问题描述
我想使用这里描述的PersistentObject http://www.doctrine-project.org/blog/a-doctrine-orm-odm-base-class.html ,以避免创建和删除getter和在数据库和实体设计的过程中,无限制的设置者。
I would like to be able to use the PersistentObject described here http://www.doctrine-project.org/blog/a-doctrine-orm-odm-base-class.html during development of a Symfony2 project, to avoid creating and deleting getters and setters endlessly whilst the database and entity design are in flux.
在Symfony2项目中,在简要文档(代码引用下面)中提到的配置ObjectManager之前, )?是否应该在控制器中,如果是这样,它会是什么样子?
Where in a Symfony2 project does one 'configure' the ObjectManager, as suggested in the brief documentation (code quote below)? Should it be in the controller, and if so, what would it look like?
$entityManager = EntityManager::create(...);
PersistentObject::setObjectManager($entityManager);
我找不到任何工作示例(尽管我在stackoverflow中找到了Zend2框架的这个并行示例: 在Zend Framework中使用Doctrine中的PersistentObject
I cannot find any working examples (although I did find this parallels example for the Zend2 framework on stackoverflow: Using PersistentObject from Doctrine in Zend Framework
感谢您的时间!
推荐答案
PersistentObject 是一个您不需要手动持久化的对象,使用php的 __ call()
方法
The PersistentObject is an object which you don't manually have to persist. It thereby provides magic getters and setters using php's __call()
method.
您只需扩展对象即可在您的实体类中并将其用于控制器中,而无需生成getter和setter。
You simply extend the Object in your entity class and use it inside your controller. without the need to generate getters and setters.
示例实体
<?php
namespace Vendor\YourBundle\YourEntity;
use Doctrine\Common\Persistence\PersistentObject;
use Doctrine\Common\Persistence\ObjectManager;
use Doctrine\ORM\Mapping as ORM;
class YourEntity extends PersistentObject
{
// i added the constructor in order to save the setObjectManager()
// call in the the controller
public function __construct(ObjectManager $om)
{
$this->setObjectManager($om);
}
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(type="string", length=100)
*/
protected $name;
// ... more properties
}
示例控制器操作
class YourController extends Controller
{
public function yourAction($name)
{
$em = $this->get('doctrine')->getManager('default');
$entity = new YourEntity($em); // __construct calls setObjectManager($em)
$entity->setName($name); // magic setter is used here
// ... no need for $em->persist($entity);
$em->flush(); // $entity is being persisted.
}
// ...
你得到在一个symfony控制器中使用以下之一的学说实体经理:
You get the doctrine entity manager inside a symfony controller using one of ...
$em = $this->get('doctrine')->getManager(); // gets default manager
$em = $this->get('doctrine')->getManager('default'); // same as above
$em = $this->getDoctrine()->getManager(); // using alias
