Symfony 2.3/Doctrine2个人翻译无法在Sonata Admin中使用TranslatedFieldType.php
我目前正在进行一个symfony2.3项目，doctrine2试图在Sonata后端实现个人翻译管理 翻译基于doctrine2可翻译行为模型： 更准确地说，是个人翻译 管理员表单使用的是symfony2.3版本的 我的实体类如下所示：Symfony 2.3/Doctrine2个人翻译无法在Sonata Admin中使用TranslatedFieldType.php,symfony,doctrine-orm,behavior,sonata-admin,symfony-2.3,Symfony,Doctrine Orm,Behavior,Sonata Admin,Symfony 2.3,我目前正在进行一个symfony2.3项目，doctrine2试图在Sonata后端实现个人翻译管理 翻译基于doctrine2可翻译行为模型： 更准确地说，是个人翻译 管理员表单使用的是symfony2.3版本的 我的实体类如下所示： <?php namespace Hr\OnlineBundle\Entity; use Doctrine\Common\Collections\ArrayCollection; use Gedmo\Mapping\Annotation as Gedmo;

这可能是什么原因？谢谢 帮自己一个忙，不要使用Gedmo可翻译行为。这是非常有缺陷，速度慢，有很多奇怪的边缘情况。我建议使用非常好的（需要PHP5.4）或类似的，但可以在PHP5.3上工作的。免责声明：最后一篇是我写的。这是测试版，但工作正常。我刚刚添加了它的文档
您可以使用在Sonata Admin中集成所有功能。帮自己一个忙，不要使用Gedmo可翻译行为。这是非常有缺陷，速度慢，有很多奇怪的边缘情况。我建议使用非常好的（需要PHP5.4）或类似的，但可以在PHP5.3上工作的。免责声明：最后一篇是我写的。这是测试版，但工作正常。我刚刚添加了它的文档
您可以使用在Sonata Admin中集成所有功能。谢谢您的回复。我们的生产服务器仍然在PHP5.3上，因此目前我无法使用KNP可翻译行为。有没有说明如何使用Prezent Translateable的文档？我已经添加了文档：嘿，我不知道你为什么要这样使用Translateable。。我已经很容易地配置了它，不需要您上面写的所有东西O也许是因为2013年，但现在，它很容易使用。谢谢你的回复。我们的生产服务器仍然在PHP5.3上，因此目前我无法使用KNP可翻译行为。有没有说明如何使用Prezent Translateable的文档？我已经添加了文档：嘿，我不知道你为什么要这样使用Translateable。。我已经很容易地配置了它，不需要您上面写的所有东西O也许是因为2013年，但现在，它很容易使用。
