Cloud Code add attribute to response

Question

I need to modify / add an attribute to a Parse object before returning it, but not save it to the database.

Here's my scenario: I do a query for a single record and when successful, I need to add a field to that object:

... query.first({

  success: function(result) {



  // get current and expiration date and calculate expiration

  var now = new Date();

  var expiresInHours = moment(results.get("expiresAt")).diff(now, 'hours');



  // set attribute                        

  result.add("expiration", expiresInHours);       



  // respond to client

  response.success(result);

The problem is that I always get an error, because I modified an object and didn't save it.

I would really like to return just the object instead of having to create a new object like

var answer = {"data": result, "expiration": expiresInHours};

which would work, but then I would need to change a lot of code on the client side....

Any help? Thx, Martin.

On using the "set" method for the object, it will try to save the object where that particular column will not be there so try converting the result to a JSON and try inserting attr to the objects.

var resultsJson = [];
for (var i = 0; i<results.length; i++) {
 var resultJson = (results[i].toJSON());
  if (relations[results[i].get("user").id] != null) {
   resultJson["relationship"] = someValue;
  }
 resultsJson.push(resultJson);
}
response.success(resultsJson);`
