Migrating from Squeryl 0.9.5 to 0.9.6

Question

I am trying to migrate an existing application fron SQueryl 0.9.5 to 0.9.6, in order to make use of the new extended field types. I am now to the point where the application and its tests compile, but I get a runtime error as soon as I try to load a Schema.

A portion of the rather long stacktrace includes this:

[error] ModelSpec.withDB(ModelSpec.scala:14)

[error] org.squeryl.internals.FieldMapper$$anonfun$get$1.apply(FieldMapper.scala:299)

Having a look at the source it seems that the exception comes from the failure of the FieldMapper.lookup method, namely the line

if(!c.isPrimitive)
  registry.get(c)

As far as I understand, mapping for classes are loaded via the register method, and in particular for the native types we have the lines

  protected def initialize {
    import PrimitiveTypeSupport._

    register(byteTEF)
    register(intTEF)
    register(longTEF)
    register(floatTEF)
    register(doubleTEF)
    register(bigDecimalTEF)

    register(binaryTEF)
    register(booleanTEF)
    register(stringTEF)
    register(timestampTEF)
    register(dateTEF)
    register(uuidTEF)

I am not sure how to load my personal extended primitive types in this registry, so that they will be used correctly.

Does anyone know what is the mechanism through which I should enable extended primitive types?

EDIT:

Here is my model - it seems to me that it looks like the "official" example, save for the fact that I am not using directly Joda time but a thin wrapper around it, which is called DateTime

object DateTime extends PrimitiveTypeMode {
  import org.squeryl._
  import org.squeryl.dsl._

  implicit val timeTEF = new NonPrimitiveJdbcMapper[Long, DateTime, TLong](longTEF, this) {
    def convertFromJdbc(t: Long) = DateTime(t)
    def convertToJdbc(t: DateTime) = t.timestamp
  }

  implicit val optionTimeTEF =
    new TypedExpressionFactory[Option[DateTime], TOptionLong]
      with DeOptionizer[Long, DateTime, TLong, Option[DateTime], TOptionLong] {

    val deOptionizer = timeTEF
  }

  implicit def timeToTE(s: DateTime) = timeTEF.create(s)

  implicit def optionTimeToTE(s: Option[DateTime]) = optionTimeTEF.create(s)
}

Corrected answer :

You are importing the org.squeryl.PrimitiveTypeMode companion object and also your own extension (object DateTime extends PrimitiveTypeMode)

You can only use on or the other in a same application (see http://squeryl.org/0.9.6.html)

The org.squeryl.PrimitiveTypeMode companion object is now deprecated (the trait with the same name isn't)

Old (wrong) answer :

You don't need to register your custom types, the register is only for primitive JDBC types, it is a closed set.

See this example : https://github.com/max-l/squeryl-extended-field-types-example JodaDate is backed by the (already registered) Timestamp primitive type.
