Phantom DSL modeling case classes

Question

I know scala and/or JVM have a limitation with 22 more fields on case classes and the best way is to split into more than one case class eg:

case class User(id: Long, username: String, password: String, address: Address)
case class Address(id: Long, street: String, city: String)

But looking at phantom dsl documentation, all docs and examples points to a single case class.

The only exception I can see, is using JsonTable showing in this test.

https://github.com/websudos/phantom/blob/develop/phantom-dsl/src/test/scala/com/websudos/phantom/tables/JsonTable.scala

The question is... how can I model inner case class using phantom-dsl for large tables?

EDIT

Just to be clear they object I'm trying to mapping into phantom.

Imagine a cassandra table with 30, 40 fields. How should I map table using case classes? Since I will receive those fields by json through a rest service, is the JsonTable example the correct approach?

Answer 1

Since scala 2.11 does not have anymore case classes 22 fields limitation, you can declare all of your fields flat or use the jsonTable examples to abstract the structure.
