-This can be done by simply calling the [https://trac.sahana3.org/wiki/BluePrintREST RESTlike controller] with the var {{{?format=json}}}:
-{{{
-/sahana/module/resource?format=json           # Lists all records of this resource

-The underlying output functions are very easy within Web2Py since 1.55:
-{{{
-def display_json():
-    "Designed to be called via AJAX to be processed within JS client."
-    list = db(db.table.id==t2.id).select(db.table.ALL).json()
-    response.view = 'plain.html'
-    return dict(item=list)
