Symfony 3上的Sonata Admin实体翻译

是否有人成功地在Symfony 3上翻译Sonata Admin实体（实际上我使用的是3.3） .

我尝试了不同的解决方案，使用gedmo转换时，主要问题是为数据库上的不同语言保存了翻译，但是在管理员（列表结束表单）中，Sonata包仅显示默认的语言环境转换，尽管单击了不同的标记/翻译/选用 .

我也尝试过使用KNP tarnslation bundle，并使用A2lix转换，但是这两个有同样的问题：当你设置（在admin类中）一个字段为“sortable”然后在你尝试按字段排序时在记录列表中，Symfony抛出一个错误，因为翻译系统试图与另一个不存在的字段 Build 关联！

无论如何，坚持Gedmo灵魂，主要的问题是（由于我已经提到过的问题，将A2lix解决方案分开）我不知道如何在管理类（BlogPostAdmin.php）中设置字段可翻译，因为只是使用配置文件以及实体和翻译类似乎不起作用 . 如前所述，问题在于翻译保存在数据库中，但不会显示在管理列表/表单中 .

这是我的配置和实体文件：
