how to make two queries atomic in parse.com in beforeSave and afterSave triggers -

i made 2 classes in parse user(by default) , userdata. beforesave trigger follows:

parse.cloud.beforesave(parse.user, function(request, response) { var userdataobject = new parse.object("userdata"); var fromuserpointer = {"__type":"pointer","classname":"_user","objectid":request.object.id};   return userdataobject.save({score: 0, ideascount: 0, followerscount:0, return:0}).then(function (userdata) {     var userdatapointer = {"__type":"pointer","classname":"userdata","objectid":userdata.id};     request.object.set("userdata", userdatapointer);     response.success(); }, function(error) {     response.error(error.message); }); 

});

it saves user's userdata , takes userdata pointer field , saves in userdata class.

parse.cloud.aftersave(parse.user, function(request) {    parse.cloud.usemasterkey(); var userpointer = {"__type":"pointer","classname":"_user","objectid":request.object.id}; var userdata = request.object.get("userdata"); if (userdata) {     var userdatapointer = {"__type":"pointer","classname":"userdata","objectid":userdata.id};     var userdataquery = new parse.query("userdata");     userdata.set("user", userpointer);     return userdata.save().then (function (userdata) {         var activityobject = new parse.object("activity");         return activityobject.save({fromuserdata: userdatapointer, from:userpointer,              touserdata:userdatapointer, to:userpointer, type:"follow"});     }).then (function (success) {      }, function (error) {         console.error("error in aftersave(user) : " + request.object.id + ":" + error.message);     });      } 

});

the problem that, before saving in user class, not create userdata, should create. hence these 2 triggers must run atomically, not.
