[英]Could not find implicit value for parameter tt: slick.ast.TypedType[List[List[Int]]]
In postgres I am trying to map column of type integer[][] using slick 3.2 在postgres中,我尝试使用slick 3.2映射类型integer [] []的列
When trying to define below 尝试在下面定义时
def bbox = column[List[List[Int]]]("bbox")
I get the following error 我收到以下错误

def * = (name, bbox) <> (Something.tupled, Something.unapply)
}
val query = TableQuery[SomethingTable]
In build.sbt
one should add 在build.sbt
应该添加
libraryDependencies += "com.github.tminglei" %% "slick-pg" % "0.16.2"
