Question

我使用symfony2.4和KNP教义行为可翻译。

我有实体Site（用于ID，主机，已启用）和实体SiteTranslation（对于已翻译的字段：名称，说明，...）。

我使用查询来获得结果

$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。对于来自Site实体的ID，主机和已启用字段，这很容易：

{{ item.id }}

但是我无法打印翻译的字段（名称，描述，......）

{{ item.name }}

它不起作用。

错误讯息：

ContextErrorException：警告：call_user_func_array（）期望参数1是有效的＆gt;回调，类'Net \ ConBundle \ Entity \ SiteTranslation'在＆gt; D：\ Users ...中没有方法'name' vendor \ knplabs \ doctrine-＆gt; behavior \ src \ Knp \ DoctrineBehaviors \ Model \ Translatable \ TranslatableMethods.php第140行

可翻译字段的getter和setter位于SiteTranslation实体中。

更新

我仍然没有找到错误的解决方案。

这是Site实体：

Answer 1

<强> TL; DR：

作为（可能是脏的）解决方法，请使用

{{ item.getName }}

在您的Twig模板中

而不是

{{ item.name }}

<强>解释

我遇到了同样的问题，我认为在与Twig一起使用时，这应该被认为是Knp DoctrineBehaviors文档中的一个错误。当你在Twig模板中调用它时：

{{ item.name }}

这是Twig在幕后获取name属性的原因：

尝试获取name对象

item

如果找不到，请检查name对象的item公共方法
如果找不到，请检查＆＃34;项目＆＃34;的getName()公共方法。对象
如果找不到，请检查__call()魔术方法（并使用name参数调用它）

此处的问题是第4步。您定义的神奇__call()方法（正如DoctrineBehaviors官方文档所推荐）使用name参数而不是getName进行调用。然后，它会调用尝试调用翻译课程的proxyCurrentLocaleTranslation()公共方法的name方法。当然，它不存在，因为你只有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。

Answer 2

这项工作对我来说：

public function __call($method, $arguments)
{
    try {
        return $this->proxyCurrentLocaleTranslation($method, $arguments);
    } catch (\Symfony\Component\Debug\Exception\ContextErrorException $e) {
        return $this->proxyCurrentLocaleTranslation('get' . ucfirst($method), $arguments);
    }

}

Answer 3

您尚未将所有可翻译属性/方法移至<Name>Translation类。

该异常明确指出您的SiteTranslation类中没有name / getName方法。
