详情

我正在使用翻译包.所以在我的表单中，对于每个字段，我都有两种语言的字段.表单完美呈现多语言选项.但是当我提交表单时，出现以下错误:

I am using translation bundle. So in my form, for each field I am having that fields for two languages. The form is rendering with multi-language options perfectly. But when I submits the form, I am getting below error:

无法确定属性translations"的访问类型.

Could not determine access type for property "translations".

推荐答案

大多数情况下，当您忘记在实体类的构造函数中初始化集合时，会抛出此错误.

Most of the time this error gets thrown when you forget to initialize a collection in the constructor of your entity class.

看看你的实体类.您需要添加

Look at your entity class. You need to add

 $this->translations = new ArrayCollection();

到构造函数.

更一般地说，PropertyAccess 负责调用实体的 setter/getter，因此通常是与实体类相关的问题，而不是与表单类型相关的问题.

More generally, PropertyAccess is responsible for calling the setters/getters of your entity so usually it is a problem related to your entity class and not your form type.
