CouchDB Validation Functions in Scala

Sample Session

// Create a document with pass thru validation function in design document
// create a design document with a validation function in Scala that passes thru everything

val vfn = """(ndoc: dispatch.json.JsValue,
  odoc: dispatch.json.JsValue, req: Any) => {}"""

val d = DesignDocument("foo_1", null, Map[String, View](), vfn)
d.language = "scala"
val de = Doc(test, d._id)
d._id should equal("_design/foo_1")
http(de add d)

// creation of a document should be successful
http(test doc Js("""{"item":"oranges","prices":{"Fresh Mart":1.99,"Price Max":3.19,"Citrus Circus":1.09}}"""))

Validation functions can be more complicated and all features of Scala can be used to do meaningful validation for documents. Have a look at ScalaValidationSpec test suite for details.
