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 // 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; /** * @MongoDB\Document * @MongoDB\ChangeTrackingPolicy("DEFERRED_EXPLICIT") */ class Vote extends BaseVote { /** * @MongoDB\Id */ protected $id; /** * Comment of this vote * * @var Comment * @MongoDB\ReferenceOne(targetDocument="MyProject\MyBundle\Document\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：

<?php // 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; /** * @MongoDB\Document * @MongoDB\ChangeTrackingPolicy("DEFERRED_EXPLICIT") */ class Comment extends BaseComment implements VotableCommentInterface { // .. fields /** * @MongoDB\Int * @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; }

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.
