FOSCommentBundle功能包：设置Doctrine ORM映射（投票）
Step 12a: Setup Doctrine ORM mapping
The ORM implementation does not provide a concrete Vote 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.
ROM实现并没有提供一个具体的Vote类给您使用，您需要创建一个。这可以通过扩展功能包提供的抽象实体并创建一个相应的映射来实现。
For example:
例如：
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22

<?php
// src/MyProject/MyBundle/Entity/Vote.php
namespace
MyProject\MyBundle\Entity;
use
Doctrine\ORM\Mapping
as
ORM;
use
FOS\CommentBundle\Entity\Vote
as
BaseVote;
/**
* @ORM\Entity
* @ORM\ChangeTrackingPolicy("DEFERRED_EXPLICIT")
*/
class
Vote
extends
BaseVote
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\generatedValue(strategy="AUTO")
*/
protected
$id
;
/**
* Comment of this vote
*
* @var Comment
* @ORM\ManyToOne(targetEntity="MyProject\MyBundle\Entity\Comment")
*/
protected
$comment
;
}
|
And you should implement VotableCommentInterface in your Comment class and add a field to your mapping:
并且您需要在您的Comment类中实现 VotableCommentInterface 接口，并添加一个字段到您的映射中：

use
FOS\CommentBundle\Entity\Comment

BaseComment;
use
FOS\CommentBundle\Model\VotableCommentInterface;
/**

class
Comment
extends
BaseComment
implements
VotableCommentInterface
{
// .. fields
/**
* @ORM\Column(type="integer")
* @var int
*/
protected
$score
= 0;
/**
* Sets the score of the comment.
*
* @param integer $score
*/
public
function
setScore(
$score
)
{
$this
->score =
$score
;
}
/**
* Returns the current score of the comment.
*
* @return integer
*/
public
function
getScore()
{
return
$this
->score;
}
/**
* Increments the comment score by the provided
* value.
*
* @param integer value
*
* @return integer The new comment score
*/
public
function
incrementScore(
$by
= 1)
{
$this
->score +=
$by
;
}
}

# app/config/config.yml
fos_comment:
db_driver: orm
class
:
model:
vote: MyProject\MyBundle\Entity\Vote

Or if you prefer XML:
如果您偏好XML:

# app/config/config.xml
<
fos_comment:config
db-driver

<
fos_comment:class
>
<
fos_comment:model
vote
=
"MyProject\MyBundle\Entity\Vote"
/>
</
fos_comment:class
>
</
fos_comment:config

Back to the main step（返回主步骤）
