Body
My guess would be that you split your methods so that you can create a different routes for the ones with and without body. It seems that the design of the code would not work even if the empty string was parsed as JSON. The map method would not be executed because there would be no user. That would cause the match on operation to never be executed. Update Since you mentioned DRY, I would refactor it into something like this: <pre><code> type Operations = PartialFunction[String, String] val operations: Operations = { case "retrieve" => println("performing retrieve") "retrieved" case "list" => println("performing list") "listed" } def userOperations(user: User): Operations = { case "create" => println("actual create operation") "created" case "delete" => println("actual delete operation") "updated" case "update" => println("actual update operation") "updated" } def withoutUser(operation: String) = Action { execute(operation, operations andThen successResponse) } def withUser(operation: String) = Action(parse.json) { request => request.body.asOpt[User].map { user => execute(operation, userOperations(user) andThen successResponse) } .getOrElse { errorResponse("invalid user data") } } def execute(operation: String, actualOperation: PartialFunction[String, Result]) = if (actualOperation isDefinedAt operation) { try { DBGlobal.db.withTransaction { actualOperation(operation) } } catch { case _ => errorResponse(operation + " error") } } else { errorResponse(operation + " not found") } val successResponse = createResponse(Ok, "Success", _: String) val errorResponse = createResponse(BadRequest, "Error", _: String) def createResponse(httpStatus: Status, status: String, message: String): Result = httpStatus(Json.toJson(Map("status" -> status, "message" -> message))) </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.
