Body
This gets you almost there. There is still a Map I don't get easily rid of. The basic approach is to have a somewhat artificial parameter types, which inherit from a common type. This way the apply method just takes a single vararg. Using implicit conversion method I get rid of the ugly constructors for the parameter types <pre><code>case class Child case class Person(stringParms: Map[String, String], mapParms: Map[String, Map[String, String]], children: List[Child]) { } sealed abstract class PersonParameter case class MapParameter(tupel: (String, Map[String, String])) extends PersonParameter case class StringParameter(tupel: (String, String)) extends PersonParameter case class ChildParameter(child: Child) extends PersonParameter object Person { def apply(params: PersonParameter*): Person = { var stringParms = Map[String, String]() var mapParms = Map[String, Map[String, String]]() var children = List[Child]() for (p ← params) { p match { case StringParameter(t) ⇒ stringParms += t case MapParameter(t) ⇒ mapParms += t case ChildParameter(c) ⇒ children = c :: children } } new Person(stringParms, mapParms, children) } implicit def tupel2StringParameter(t: (String, String)) = StringParameter(t) implicit def child2ChildParameter(c: Child) = ChildParameter(c) implicit def map2MapParameter(t: (String, Map[String, String])) = MapParameter(t) def main(args: Array[String]) { val firstChild = Child() val secondChild = Child() val bob: Person = Person("name" -> "Bob","pets" -> Map("cat" -> "Mittens", "dog" -> "Spot"),"status" -> "asleep", firstChild, secondChild) println(bob) } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
