Can't make schema into cassandra using phantom-dsl - scala

Question

Trying to create a schema into cassandra using phantom-dsl for unit testing following this tutorial:
http://outworkers.com/blog/post/phantom-tips-3-understanding-phantom-connectors
I ran into this issue when trying to auto-generate schema
[ERROR] /home/.../test/BaseCassandraSpec.scala:54: error: not enough arguments for method autocreate: (keySpace: com.websudos.phantom.connectors.KeySpace)
com.websudos.phantom.builder.query.CreateQuery.Default[com.neruti.db.models.ConcreteUserModel,com.neruti.User].
[ERROR] Unspecified value parameter keySpace.
[ERROR] Await.result(database.userModel.autocreate().future(),10.seconds)
Any advice?
Currently using version 1.29.6

import com.websudos.phantom.dsl.KeySpaceDef
object Connector {
// TODO: these key value pairs shld get from HOCON config file
val host= Seq("127.0.0.1")
val port = 9042
val keySpace: String = "nrt_entities"
// val inet = InetAddress.getByName
lazy val connector = ContactPoints(host,port).withClusterBuilder(
_.withCredentials("dev", "nrtDev1989")
).keySpace(keySpace)
// embedded cassandra is not supported anymore. Check phantom-sbt.
// lazy val testConnector: KeySpaceDef = ContactPoint.embedded.keySpace(keySpace)
lazy val testConnector: KeySpaceDef = ContactPoints(host,port).noHeartbeat().keySpace(keySpace)
}

I would upgrade to phantom 2.0.0 as a side note. Next, there are many things to improve in your code, starting with capitalisation of the traits.
You should use database.create or database.createAsync, which no longer require you to re-pass the implicit keyspace or session. Bear in mind this API is version 2.1.1 of phantom-dsl, available on Maven Central.
package com.neruti.db
import com.neruti.db.models._
import com.outworkers.phantom.connectors.ContactPoints
import com.outworkers.phantom.dsl._
object Connector {
// TODO: these key value pairs shld get from HOCON config file
val host= Seq("127.0.0.1")
val port = 9042
val keySpace: String = "nrt_entities"
// val inet = InetAddress.getByName
lazy val connector = ContactPoints(host,port).withClusterBuilder(
_.withCredentials("dev", "nrtDev1989")
).keySpace(keySpace)
lazy val testConnector: KeySpaceDef = ContactPoints(host, port).noHeartbeat().keySpace(keySpace)
}
class MyDb(override val connector: CassandraConnection) extends Database(connector) {
... tables
}
object TestMyDb extends MyDb(Connector.testConnector)
import com.outworkers.phantom.dsl.context
// Now this will only require an execution context, nothing more
TestMyDb.create()
