I am migrating from slick-extenstions to slick 3.2.0

import slick.lifted.{ProvenShape, Tag}
import slick.model.Table


class Admin(tag : Tag) extends Table[(Long, Long)](tag, "NT_CV_ADMIN_SHORT") {
  def parentId = column[Long]("PARENT_ID")
  def maxAdminShort = column[Long]("MAX_ADMIN_SHORT")

  override def * : ProvenShape[(Long, Long)] = (parentId, maxAdminShort)
}

For the above declaration of table I am getting following error - error: slick.model.Table does not take type parameters

Here is the dependency I used -

<dependency>
            <groupId>com.typesafe.slick</groupId>
            <artifactId>slick_2.12</artifactId>
            <version>3.2.0</version>
</dependency>

I don't understand what I am missing. I saw slick3.2.0 manual - https://scala-slick.org/doc/3.2.0/gettingstarted.html, that's how I have created the table. I don't know if I am missing something?

CodePudding user response：

You've imported the wrong Table.

Slick is kinda confusing in that it wants you to get most of your imports from a "driver" class. The getting started guide you linked tells you to add these imports:

import slick.jdbc.H2Profile.api._

import scala.concurrent.ExecutionContext.Implicits.global

If you were using a different database e.g. MySQL you would import slick.jdbc.MySQLProfile.api._ instead.

Here are the scaladocs for the api type: https://scala-slick.org/doc/3.2.0/api/index.html#slick.jdbc.JdbcProfile$API - as you can see from that page, the api provides a whole bunch of type aliases and values. The Table you want is the one in there.
