Handling codegen def and class when case class does not exist

[ergomesh]

I have a slick codegen that I want to json.toJson for my results sets. Here is an example of a 22+ tuple

implicit def Table1Row(implicit e0: GR[String], e1: GR[Long], e2: GR[Option[String]]): GR[Table1Row] = GR{ prs => import prs._ <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[Long] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[String] :: <<[Long] :: <<[String] :: <<[String] :: <<?[String] :: HNil } /** Table description of table TABLE1. Objects of this class serve as prototypes for rows in queries. */ class Table1(_tableTag: Tag) extends Table[Table1Row](_tableTag, Some("Schema"), "TABLE1") { def * = x1 :: x2 :: x3 :: x4 :: x5 :: x6 :: x7 :: x8 :: x9 :: x10 :: x11 :: x12 :: x13 :: x14 :: x15 :: x16 :: x17 :: x18 :: x19 :: x20 :: x21 :: x22 :: x23 :: x24 :: x25 :: x26 :: x27 :: x28 :: x29 :: x30 :: x31 :: x32 :: x33 :: x34 :: x35 :: x36 :: x37 :: x38 :: x39 :: x40 :: x41 :: x42 :: x43 :: x44 :: x45 :: x46 :: x47 :: x48 :: x49 :: x50 :: x51 :: x52 :: x53 :: x54 :: HNil

Is there any way to render this as Json using the extension?

No. This extension does not support Slick's HList. Hopefully somebody will implement additional features for the Slick code generator as a Google Summer of Code project.
