Twig 具有额外列的细枝关系

我有一个问题，不知道解决它的最佳做法

我想为我的核心数据创建一个表单。核心数据都是可版本的。 我用GUID解决了它，以了解版本的一致性

现在我有两个可版本化的实体

AgeClass

和

HighscoreList

，它们可以有多对多关系。关系也必须是可版本的，所以我创建了一个

ReferenceEntity

RefAgeClassHighscoreList

。现在我有了与额外列的关系

有效期为[和]
有效的

但是现在我不知道我应该如何建立我的形式。 编辑

AgeClass

时，所有当前（有效）

HighscoreList

项目都应显示为复选框。 但是当我构建编辑表单时，这些值必须与

RefAgeClassHighscoreList

实体绑定

我希望你能理解我的问题

嗯，你有一个非常重复和乏味的问题。您可以使用AgeClass执行一个操作，并为RefAgeClassHighscoreList类型嵌入一个表单。在这种嵌入形式中，您可以拥有HighscoreList类型的属性，问题是您需要的默认呈现组件是HighscoreList的多选列表，您可以看到它将属性multiple=true设置为HighscoreList的属性

要将该列表转换为复选框列表，您需要创建一个自定义块，以扩展或向symfony提供的默认块添加新块。我的建议是使用表单名称为特定表单创建新的小部件和行。你可以找到很多关于我提到的内容的文档，并且需要每个文档的一小部分来满足你的要求

希望这些线索对你有所帮助
