Forms Symfony2在表单集合中更新特定字段

我有一个有趣的问题。我在stackoverflow和google中找不到任何解决方案。我有一个实体

User

和

User

有一些元。所以我创建了一个

UserMeta

实体和

UserMetaValue

。在用户表单中有许多选项卡。我在选项卡中使用了这些元。有些在第一个选项卡中，有些在其他选项卡中。所有选项卡都有自己的形式。当我在活动选项卡上绑定表单时，活动选项卡元将更新，而其他选项卡元将更改为NULL

我通过使用IF语句在twig文件中检查集合字段来过滤集合字段

---

我又问了一个问题，如何在同一页面中使用不同形式的meta而不影响其他页面？

过滤掉不相关字段以进行渲染的工作已经完成了一半。但是您还需要过滤掉表单绑定的无关字段

当您将请求绑定到表单时，它期望每个

UserMeta

实体都有值，因为在

UserMetaType

集合中有一个字段用于所有实体。您需要删除所有与您提交的值之一不对应的

UserMetaType

表单。最好使用

FormEvents:：PRE_BIND

侦听器

您可以在中看到一个更简单的示例。这对您来说会稍微复杂一点，因为您必须遍历

UserMetaType

表单的集合，并删除您不希望绑定的表单。
