Step 12b: Setup MongoDB mapping

The MongoDB implementation does not provide a concrete Vote class for your use,you must create one:

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：

<?php
// class="lazy" data-src/MyProject/MyBundle/Document/Vote.php
namespace MyProject\MyBundle\Document;
use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;
use FOS\CommentBundle\Document\Vote as BaseVote;

class Vote extends BaseVote
{
    
    protected $id;
    
    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：

<?php
// class="lazy" data-src/MyProject/MyBundle/Document/Comment.php
namespace MyProject\MyBundle\Document;
use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;
use FOS\CommentBundle\Document\Comment as BaseComment;
use FOS\CommentBundle\Model\VotableCommentInterface;

class Comment extends BaseComment implements VotableCommentInterface
{
    // .. fields
    
    protected $score = 0;
    
    public function setScore($score)
    {
        $this->score = $score;
    }
    
    public function getScore()
    {
        return $this->score;
    }
    
    public function incrementScore($by = 1)
    {
        $this->score += $by;
    }

Configure your application（配置您的应用程序）

In YAML:

YAML格式：

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

Or if you prefer XML:

如果您偏好XML:

# app/config/config.xml
<fos_comment:config db-driver="mongodb">
    <fos_comment:class>
        <fos_comment:model
            vote="MyProject\MyBundle\Document\Vote"
        />
    </fos_comment:class>
</fos_comment:config>

Back to the main step（返回主步骤）

Step 12: Enable voting.
