Volt Framework模型抛出错误的类型限制

Question

我想像这样为Volt模型设置类型限制

class EventItemBlock < Volt::Model :name, String :items, Volt::ArrayModel end

当我保存文件时，Volt在幕后抛出一个错误，但没有崩溃。相关的行是前七(7)行，这表明逗号是一个语法错误。

在Volt Framework文档中，逗号被记录为正确的语法(http://docs.voltframework.com/en/docs/models.html)。删除逗号并不能解决错误--只有删除类型限制才能解决错误。

好的，这里有两件事。1)错误的语法。您需要做的是：

field :something, SomeClass

其次，您目前不能仅限于Volt::ArrayModel (目前，在待办事项列表中)
