Migrating to anorm2.4 (with play 2.4): ToStatement[T] and ToStatement[Option[T]]

Question

Up until the anorm included with play 2.3, I could write the following:

implicit val arbitraryClassToStatement = new ToStatement[ArbitraryClass] {
  def set( 
          


        

Answer 1

You need to create a ParameterMetaData[ArbitraryClass] for this to work

implicit object ArbitraryClassMetaData extends ParameterMetaData[ArbitraryClass] {
  val sqlType = ParameterMetaData.StringParameterMetaData.sqlType
  val jdbcType = ParameterMetaData.StringParameterMetaData.jdbcType 
}

Here I just retook the values of ParameterMetaData[String]
