index.html.twig sylius中自定义模型的空转换集合

Question

我创建了一个自定义实体＆＃34; Faq＆＃34;与他们的路线。 当我转储＆＃34; faqs＆＃34;在我的index.html.twig中，Faq＃translations＃collection是空的。

我需要一个＆＃34;问题＆＃34;以及一个＆＃34;响应＆＃34;在集合中。 在我的数据库中，所有字段都存在于FaqTranslation中。

我可能会错过什么？

抱歉我的英语不好。

谢谢。

Answer 1

转储可以返回空集合，因为未初始化，请尝试使用{{ dump(faq.translations.toArray }}。当使用时，PersistenCollections被初始化，例如，当得到至少一个元素时。
