Question

Running a Squeryl call for some data that pulls from multiple locations, but for some reason it returns as a unit. How do I get it to return as an Iterable?

Below is pulling of the data:

/**
   * gets a stream for a particular user
   */
  def getUserStream(userId:Long) {
    User.teamIds(userId).toList.map( (team) =>
      Stream.findByTeam(team,0,5).map( (stream) => 
        List(stream)
      ).flatten
    ).flatten.sortBy(_.id)
  }

And then outputting the data, where results returns as Unit:

Stream.getUserStream(userId) match {
      case results => {
        Ok( generate(results.map( (stream) => Map(
                "id" -> stream.id,
                "model" -> stream.model,
                "time" -> stream.time,
                "content" -> stream.content
                ))
            ) ).as("application/json")
      }
      case _ => Ok("")
    }

My initial guess is one function could return as a None, but wouldn’t it just return an empty list?

You missing the equal sign before you def getUserStream(userId:Long) method body.

def func(x: Int) { x + 1 } // This will return Unit
def func(x: Int) = { x + 1 } // This will return a Int
