Разобрать облачный код после двойного срабатывания сохранения.

У меня есть послесохранение облачного кода Parse. Я внес изменения в таблицу один раз, но хук после сохранения срабатывает дважды

1-е обновление (фактическое обновление)

Input: {"object":{"addedBy":"tt","albumTitle":"ggh","approved":true,
"createdAt":"2015-12-14T03:07:27.253Z","image":
{"__type":"File","name":"tfss-e26ec608-5a0b-46a2-91db-33590139c4b3-
newImage.jpg","url":"http://files.parsetfss.com/0accbdba-e3f2-493d-
ac70-1c6bccc367b9/tfss-e26ec608-5a0b-46a2-91db-33590139c4b3-
newImage.jpg"},"objectId":"p4pLO70gQY","updatedAt":"2015-12-
14T03:07:37.733Z"}}

2-е обновление (не должно происходить)

Input: {"object":{"addedBy":"tt","albumTitle":"ggh","approved":true,
"createdAt":"2015-12-14T03:07:27.253Z","image":
{"__type":"File","name":"tfss-e26ec608-5a0b-46a2-91db-33590139c4b3-
newImage.jpg","url":"http://files.parsetfss.com/0accbdba-e3f2-493d-
ac70-1c6bccc367b9/tfss-e26ec608-5a0b-46a2-91db-33590139c4b3-
newImage.jpg"},"objectId":"p4pLO70gQY","updatedAt":"2015-12-
14T03:07:38.038Z"}}

Единственная разница между двумя обновлениями — это время updatedAt. Будет ли срабатывать послесохранение, даже если время обновления изменится?

Как я могу избежать второго выполнения после сохранения?

Вот мой облачный код:

Parse.Cloud.afterSave("Photos", function (request) {

    var albumNameA = "";
    var publicUser = "";
    var albumOwner = "";
    var photoUniqueId = "";
    var isApproved = "";

    albumNameA = request.object.get("albumTitle");
    publicUser = request.object.get("addedBy");
    photoUniqueId = request.object.id;
    isApproved = request.object.get("approved");

    if (request.object.get("createdAt").getTime() == request.object.get("updatedAt").getTime()) {
        var getAlbumOwner = new Parse.Object.extend("Albums");
        var q3 = new Parse.Query(getAlbumOwner);
        q3.equalTo("title", albumNameA);
        q3.first({
            success: function (results) {
                console.log("Checking for Creator name " + results.get("creatorName"));
                albumOwner = results.get("creatorName");
                console.log("Uploading a Photo Final " + albumNameA + "-by-" + publicUser + "--ownedby--" + albumOwner);
                console.log("Uploading a Photo" + albumNameA + "-by-" + publicUser + "--" + photoUniqueId + "--" + isApproved);
                var install = new Parse.Object.extend("Installation");
                var q2 = new Parse.Query(install);
                q2.equalTo("privacy", privateUserNo);
                q2.equalTo("username", albumOwner);
                q2.find({
                    success: function (results) {
                        if (!isApproved) {
                            Parse.Push.send({
                                where: q2, // Set our Installation query

                                    alert: "New Photo uploaded by  " + publicUser + " ,waiting for approval"
                                }
                            }, {
                                success: function () {
                                    // Push was successful
                                    console.log("Push success");
                                },
                                error: function (error) {

                    },

        });
