symfony - Symfony2 - 可翻译字段 - 在链配置的命名空间中找不到类“Gedmo\Translatable\Entity\Translation”

Question

我正在尝试翻译实体的某些字段，但在尝试创建对象时出现以下错误...

<?php

namespace XXXX\Entity;

use Gedmo\Mapping\Annotation as Gedmo;
use Doctrine\ORM\Mapping as ORM;
use Gedmo\Translatable\Translatable;
use Doctrine\Common\Collections\ArrayCollection;

/**
 * Line
 *
 * @ORM\Table()
 * @ORM\Entity(repositoryClass="XXXX\Entity\LineRepository")
 */
class Line implements Translatable
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var string
     *
     * @Gedmo\Translatable
     * @ORM\Column(name="name", type="string", length=255)
     */
    private $name;

    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set name
     *
     * @param string $name
     * @return Line
     */
    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

    /**
     * Get name
     *
     * @return string
     */
    public function getName()
    {
        return $this->name;
    }

    public function setTranslatableLocale($locale)
    {
        $this->locale = $locale;
    }
}

和错误：

[Doctrine\Common\Persistence\Mapping\MappingException]
The class 'Gedmo\Translatable\Entity\Translation' was not found in the chain configured namespaces

我正在使用 Symfony 2.5，但也出现在 2.4 中。知道如何解决这个问题吗？

Answer 1

您还需要配置要使用的可翻译实体。在 config.yml 中：

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

Answer 2

Symfony 5 更新：配置/config/packages/doctrine.yaml文件并添加以下内容

orm:
    (....)
    mappings:
        translatable:
            type: annotation
            is_bundle: false
            prefix: Gedmo\Translatable\Entity
            dir: '%kernel.project_dir%/vendor/gedmo/doctrine-extensions/src/Translatable/Entity'
            alias: GedmoTranslatable
