Thanks guys, I happened to be looking for this right now.
For those looking to output single Boxed result from findAll, I think
you would do something like this:
JsonResponse(JsObj("results" -> Node.find(By(Content.id,
yourIdQuery)).openOr(Content).asJs))
The problem is that if the Content row isn't found you get a result
based upon the companion object. Is there a way to give a truely empty
JsObj when there isn't a Full Box?
I have a few additional questions based upon JsonResponse. Why not use
asJSON instead of asJs? Is this because JsonResponse requires as
JsExp? When would it be recommended to use asJSON and its String
return value?
Also, I notice that the JsExp produced by calling asJs on a model
includes '$lift_class': 'nodes'. People might not want to expose that
in their final JSON output...
