Where in select using Phantom doesn't resolve - scala

Question

I have been toying around with the smiple code provided in the phantom wiki, the follow I have tried;
import com.websudos.phantom.dsl._
case class Student(id: UUID, name: String)
class Students extends CassandraTable[Students, Student] {
object id extends UUIDColumn(this) with PartitionKey[UUID]
object name extends StringColumn(this)
def fromRow(row: Row): Student = {
Student(id(row), name(row))
}
}
object Students extends Students with Connector {
def getByName(name: String): Future[Option[Student]] = {
select.where(_.name eqs name).one()
}
}
But my IDE keeps saying Cannot resolve symbol where and the compiler says value where is not a member of com.websudos.phantom.builder.query.RootSelectBlock[Students,Student]
I'm using Scala 2.11.6 and Phantom 1.10.1, all help is greatly appreciated!

Answer 1

I ran into this issue and resolved this using #flavian's suggestion above.
Ensure that your Connector has an implicit keyspace defined.
This is directly lifted from the example project.
trait KeyspaceDefinition {
implicit val keySpace = KeySpace("sample_keyspace")
}
trait Connector extends SimpleConnector with KeyspaceDefinition

You are missing out on a fundamental Cassandra issue, you cannot query by name as it's not an indexed column. Based on the table you've just defined, the query you are trying to perform is invalid and Cassandra will tell you that at runtime.
Phantom will prevent most bad things at compile time. It's worth reading through this blog series to understand how things work in Cassandra.
To put things in perspective, the only where query that's valid for your Students table is:
def getById(id: UUID): Future[Option[Student]] = {
select.where(_.id eqs id).one()
}
