Step 2a: Setup Doctrine ORM mapping

The ORM implementation does not provide a concrete Comment class for your use,you must create one. This can be done by extending the abstract entities provided by the bundle and creating the appropriate mappings.

ORM实现并不提供为您所用的具体评论类，您必须要创建一个。您可以通过功能包提供扩展抽象实体类并创建适当的映射。

For example:

例如：

<?php
// src/MyProject/MyBundle/Entity/Comment.php
namespace MyProject\MyBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use FOS\CommentBundle\Entity\Comment as BaseComment;
/**
* @ORM\Entity
* @ORM\ChangeTrackingPolicy("DEFERRED_EXPLICIT")
*/
class Comment extends BaseComment
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* Thread of this comment
*
* @var Thread
* @ORM\ManyToOne(targetEntity="MyProject\MyBundle\Entity\Thread")
*/
protected $thread;
}

还有线索类：

<?php
// src/MyProject/MyBundle/Entity/Thread.php
namespace MyProject\MyBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use FOS\CommentBundle\Entity\Thread as BaseThread;
/**
* @ORM\Entity
* @ORM\ChangeTrackingPolicy("DEFERRED_EXPLICIT")
*/
class Thread extends BaseThread
{
/**
* @var string $id
*
* @ORM\Id
* @ORM\Column(type="string")
*/
protected $id;
}

Configure your application（配置您的应用程序）

# app/config/config.yml
fos_comment:
db_driver: orm
class:
model:
comment: MyProject\MyBundle\Entity\Comment
thread: MyProject\MyBundle\Entity\Thread
assetic:
bundles: [ "FOSCommentBundle" ]

Or if you prefer XML:

或者您喜爱XML：

# app/config/config.xml
<fos_comment:config db-driver="orm">
<fos_comment:class>
<fos_comment:model
comment="MyProject\MyBundle\Entity\Comment"
thread="MyProject\MyBundle\Entity\Thread"
/>
</fos_comment:class>
</fos_comment:config>
<assetic:config>
<assetic:bundle name="FOSCommentBundle" />
</assetic:config>

Back to the main step（返回主步骤）

Step 2: Create your Comment and Thread classes.

第2步：创建您的评论类和线索类。
