 def json_response(f, *args, **kwargs):
 """Wrap a view in JSON. This decorator runs the given function and looks out for ajax.AJAXError's, which it encodes into a proper HttpResponse object. If an unknown error is thrown it's encoded as a 500. All errors are then packaged up with an appropriate Content-Type and a JSON body that you can inspect in JavaScript on the client. They look like: { "message": "Error message here.", "code": 500 } Please keep in mind that raw exception messages could very well be exposed to the client if a non-AJAXError is thrown. """
