尝试翻译实体Symfony2时出现问题

Question

我试图用Gedmo translatable在Symfony2中设置一些可翻译的内容，但似乎我做错了什么或遗漏了什么。

我在composer.json文件中包含了这一行：

"gedmo/doctrine-extensions": "2.3.*@dev"

此外，我在config.yml文件中添加了以下行：

stof_doctrine_extensions:
    orm:
        alopatria:
            timestampable: true
            sluggable: true
            translatable: true

实体类设置如下：

<?php
namespace ...;
use GedmoMappingAnnotation as Gedmo;
use DoctrineORMMapping as ORM;
use GedmoTranslatableTranslatable;
/**
* ...Entity
*
* @ORMTable(name="content")
* @ORMHasLifecycleCallbacks 
* @ORMEntity(repositoryClass="...EntityContentRepository")
*/
class Content implements Translatable
{
    /**
     *
     * @ORMColumn(name="id", type="bigint", nullable=false)
     * @ORMId
     * @ORMGeneratedValue(strategy="IDENTITY")
     */
    protected $id;
    /**
     * @GedmoTranslatable
     * @ORMColumn(name="title", type="string", length=32, nullable=false)
     */
    protected $title;
    /**
     * @GedmoTranslatable
     * @ORMColumn(name="text", type="text", nullable=false)
     */
    protected $text;
    /**
     * @var datetime $created
     *
     * @GedmoTimestampable(on="create")
     * @ORMColumn(type="datetime")
     */
    private $created;
    /**
     * @var datetime $updated
     *
     * @GedmoTimestampable(on="update")
     * @ORMColumn(type="datetime")
     */
    private $updated;
    /**
     * @var datetime $contentChanged
     *
     * @ORMColumn(name="content_changed", type="datetime", nullable=true)
     * @GedmoTimestampable(on="change", field={"title", "text"})
     */
    private $contentChanged;
    /**
     * @GedmoSlug(fields={"title"})
     * @ORMColumn(length=128, unique=true)
     */
    private $slug;

    /**
     * Get id
     *
     * @return integer 
     */
    public function getId()
    {
        return $this->id;
    }
    /**
     * Set title
     *
     * @param string $title
     * @return Content
     */
    public function setTitle($title)
    {
        $this->title = $title;
        return $this;
    }
    /**
     * Get title
     *
     * @return string 
     */
    public function getTitle()
    {
        return $this->title;
    }
    /**
     * Set text
     *
     * @param string $text
     * @return Content
     */
    public function setText($text)
    {
        $this->text = $text;
        return $this;
    }
    /**
     * Get text
     *
     * @return string 
     */
    public function getText()
    {
        return $this->text;
    }
    /**
     * Set created
     *
     * @param DateTime $created
     * @return Content
     */
    public function setCreated($created)
    {
        $this->created = $created;
        return $this;
    }
    /**
     * Get created
     *
     * @return DateTime 
     */
    public function getCreated()
    {
        return $this->created;
    }
    /**
     * Set updated
     *
     * @param DateTime $updated
     * @return Content
     */
    public function setUpdated($updated)
    {
        $this->updated = $updated;
        return $this;
    }
    /**
     * Get updated
     *
     * @return DateTime 
     */
    public function getUpdated()
    {
        return $this->updated;
    }
    /**
     * Set contentChanged
     *
     * @param DateTime $contentChanged
     * @return Content
     */
    public function setContentChanged($contentChanged)
    {
        $this->contentChanged = $contentChanged;
        return $this;
    }
    /**
     * Get contentChanged
     *
     * @return DateTime 
     */
    public function getContentChanged()
    {
        return $this->contentChanged;
    }
    /**
     * Set slug
     *
     * @param string $slug
     * @return Content
     */
    public function setSlug($slug)
    {
        $this->slug = $slug;
        return $this;
    }
    /**
     * Get slug
     *
     * @return string 
     */
    public function getSlug()
    {
        return $this->slug;
    }
}

当我试图在我的控制器中创建可翻译的内容时：

$content = new Content();
$content->setTitle('Content example');
$content->setText('Content example...');
$em = $this->getDoctrine()->getEntityManager();
$em->persist($content);
$em->flush();
$content->setTranslatableLocale('fr'); // change locale
$em->persist($content);
$em->flush();

这就是错误：

The class 'GedmoTranslatableEntityTranslation' was not found in the chain configured namespaces ...Entity, FOSUserBundleModel

有什么帮助吗？谢谢

您还需要配置要使用的可翻译实体。在配置yml:中

orm:
auto_generate_proxy_classes: %kernel.debug%
mappings:
    translatable:
        type: annotation
        is_bundle: false
        prefix: GedmoTranslatableEntity
        dir: "%kernel.root_dir%/../vendor/gedmo/doctrine-extensions/lib/Gedmo/Translatable/Entity"
        alias: GedmoTranslatable
