我使用 symfony2.4 和 KNP doctrine behaviors translatable。
我有实体 Site(用于 ID、主机、已启用)和实体 SiteTranslation(用于翻译字段:名称、描述等)。
我使用查询来获取结果
$qb = $this->createQueryBuilder('s')
->addSelect('translation') // to eager fetch translations (optional)
->leftJoin('s.translations', 'translation') // or innerJoin ?
->orderBy('s.root', 'ASC')
->addOrderBy('s.lft', 'ASC');
我想在 Twig 中打印结果。对于 Site 实体的 ID、host 和 enabled 字段很简单:
{{ item.id }}
但我无法打印翻译后的字段(名称、描述……)
{{ item.name }}
它不起作用。
错误信息:
ContextErrorException: Warning: call_user_func_array() expects parameter 1 to be a valid >callback, class 'Net\ConBundle\Entity\SiteTranslation' does not have a method 'name' in >D:\Users...\vendor\knplabs\doctrine->behaviors\src\Knp\DoctrineBehaviors\Model\Translatable\TranslatableMethods.php line 140
可翻译字段的 getter 和 setter 在 SiteTranslation 实体中。
更新:
我仍然没有找到错误的解决方案。

请您参考如下方法:
长话短说:
作为(可能很脏的)解决方法，使用
{{ item.getName }}
在你的 Twig 模板中而不是
{{ item.name }}
解释:
我遇到了同样的问题，我认为当与 Twig 一起使用时，这应该被视为 Knp DoctrineBehaviors 文档中的错误。当您在 Twig 模板中调用它时:
{{ item.name }}
这就是 Twig 在幕后获取 name 属性所做的事情:
- 尝试获取
item对象的name公共(public)属性 - 如果没有找到，检查
item对象的name公共(public)方法 - 如果没有找到，检查“item”对象的
getName()公共(public)方法 - 如果没有找到，检查
__call()魔术方法(并使用name参数调用它)
这里的问题是第 4 步。您定义的魔法 __call() 方法(如官方 DoctrineBehaviors 文档所推荐的那样)是使用 name 参数而不是获取名称。然后它会调用 proxyCurrentLocaleTranslation() 方法，该方法会尝试调用翻译类的 name 公共(public)方法。当然，它不存在，因为您只有一个 getName() 方法。
在 Twig 中查看此问题:https://github.com/twigphp/Twig/issues/342
通过直接使用 Twig 中的 {{ item.getName }} 代码，将调用正确的方法名称。
