Question

In Mapper’s having String as a primary Key, why is the MappedStringIndex not shown in the list of all fields that are obtained via the Mapper's allFields method

My Mapper goes like this …

class DummyMapper extends KeyedMapper[String,DummyMapper] {

  def getSingleton = DummyMapper
  def primaryKeyField = dummyCode

  object dummyCode extends MappedStringIndex(this,5)
  {
    override def writePermission_? = true
    override def dbAutogenerated_? = false
    override def dbNotNull_? = true
    override def dbColumnName="dummy_code"
  }
.....

I even tried it including in the fieldOrder. Still the result was same, it din’t showed up in DummyMapper.allFields list

Answer 1

primarykey fields ( of any data-type ) are not included in the list returned by allFileds method of the Mapper.

You can prepend the field separately if you want

something like

   var myMapperPrimaryKey=DummyMapper.primaryKeyField
   var fieldList=DummyMapper.allFields.toBuffer[BaseField]
   fieldList.prepend(myMapperPrimaryKey)

// Now fieldList is having the primaryKey along with other fields.
