我想删除区域设置和时区字段：

覆盖def fieldOrder = List（firstName，lastName，email，password）

但没有任何反应

不是我做错了

有人可以帮助我吗

Answer 1

你要覆盖错误的def - 应该是signupFields。


override def signupFields: List[FieldPointerType]= List(firstName, lastName, email, password)

Answer 2

我会复制MetaMegaProtoUser和MegaProtoUser，创建新特征，并使“User”对象和类扩展特征。

scala lift，从注册中删除区域设置和时区
