Setting some Parse.User property on beforeSave when running on Heroku

Question

Can you edit data in beforeSave callback and if yes, how?

Looking at various docs, it seem like this code should work (using "_User" or Parse.User) and I can see Ran beforeSave on a User and new user! in my logs but the key aaa is still empty..

I've tried to add user.save() after user.set but still no luck. Any idea?

Parse.Cloud.beforeSave("_User", function(request, response) {
  console.log('Ran beforeSave on a User');
  var user = request.object;
  if(user.existed()) {
    response.success(); 
  } else {
    console.log('new user!');
    user.set('aaa', 'xxx');
    response.success();
  }
});

EDIT 2015/12/03: Maybe critical info, this code is running on heroku. http://blog.parse.com/announcements/introducing-heroku-parse/

EDIT 2015/12/05: It seem to be a bug with Heroku / Parse integration. beforeSave hook are called but doesn't seem to allow you to edit the request.object..

EDIT 2015/12/07: I've created an issue on the CloudCode-Express repo https://github.com/ParsePlatform/CloudCode-Express/issues/6

You're trying to set value to user variable which is local. Try this : request.object.set('aaa','xxx'); — Pavan Bhushan Maganti

We're using the same user.set() function in our code and it works, even if using a local variable. We've had some problems with existed(), however, and for our use case we can go with if (!user.get('aaa')) {} instead. — paolobueno

I've tried by referencing the request.object directly before refactoring a bit.. no luck... — Hugues BR

I'm having the same problem, also running beforeSave on heroku. I think it's a bug in the Parse webhook implementation, as it did work when this was implemented directly in Parse Cloud Code. Might have to put the beforeSave back on the Parse server and not heroku until they fix it... — Cory Imdieke

Using Webhooks, you need to pass back the changed object:

response.success(object);

Change your code to use isNew() method:

Parse.Cloud.beforeSave(Parse.User, function(request, response) {
  console.log('Ran beforeSave on a User');

  if(!request.object.isNew()) {
    response.success(); 
  } else {
    console.log('new user!');
    request.object.set('aaa', 'xxx');
    response.success();
  }
});
