scala - 光滑的错误 : type TupleXX is not a member of package scala (XX > 22)

Question

我想使用提升的光滑编写一个数据库模式。我有超过 100 列的大表。所以我对所有超过 22 列的表都有这个错误:

类型 Tuple45 不是包 scala 的成员

这是其中一张表的代码:

object adrepost extends Table[(String, String, String, String, String, String, String,   String, String, String, String, String, String, String, String, String, String, Date, Boolean, Date, Int, Boolean, String, String, String, String, String, Boolean, Boolean, String, String, Boolean)]("ADREPOST") {

def idx4 = index("adrepost_matchcode", (matchcode), unique = true)
def idx5 = index("adrepost_nom1", (nom1), unique = true)
}  

关于如何解决这个问题的任何想法？

你应该看看使用嵌套元组来解决这个问题。以下帖子对我很有帮助:

Stefan 在代码中使用注释来帮助您了解正在执行的操作。

旁注:在几周前的 Slick 演讲中，我被告知这个限制正在下一个版本中解决，该版本将很快发布。
