Seeking a proficient Cloud Code specialist skilled in JavaScript, focused on managing installations and channels

My experience with Javascript is limited, but as I work on my application, I realize the necessity of incorporating it into Cloud Code. I have a Parse class called Groups where I store group data including Name, Description, Users, and Requests.

Name, Description, Users, Requests.

When a user creates a group from their device, the information is stored here with the name, description, and user pointer. I use the objectId with a "+C" character to subscribe that user to a channel for push notifications. However, I encountered an issue where push notifications were only received on the device where the group was created.

To address this issue, I believe I need to use a Parse Cloud function to ensure all installations for a specific user subscribe to the same channels.

Another challenge is ensuring that client-side notifications are handled properly when a user re-installs the application, in order to avoid receiving duplicate notifications. I am looking for a cloud function that can check for and manage multiple installations for the same user and device ID.

I believe solving these problems will not only benefit me but also others facing similar issues. Any references, example codes, or guidance on how to approach these challenges would be greatly appreciated.

Answer №1

Upon the app's opening, it is crucial for the device to subscribe to the channel:

"user_" + ParseUser.getCurrentUser().getObjectId()

Afterwards, push notifications can be sent to all devices where the user is signed in.

Addressing the initial issue:

To display Groups in a listView, I utilize a method for refreshing the list whenever a new group is added. The process is carried out as follows:

public static void updateData() {

    ParseQuery<Groups> query = ParseQuery.getQuery("Groups");
    query.whereEqualTo("members", ParseUser.getCurrentUser());
    query.setCachePolicy(ParseQuery.CachePolicy.CACHE_THEN_NETWORK);
    query.findInBackground(new FindCallback<Groups>() {
        @Override
        public void done(List<Groups> parseObjects, ParseException e) {
            if(e != null) {
                return;
            }

            for( int i = 0; i < parseObjects.size(); i++){
                Groups iter = parseObjects.get(i);
                ParsePush.subscribeInBackground("C" + iter.getObjectId());
            }

            groupsAdapter.clear();
            groupsAdapter.addAll(parseObjects);
        }
    });
}

Integrating this method within the onResume function triggers a list refresh every time the application is resumed, along with device subscription to channels created based on group objectId's.

Although the current solution suffices for now, I acknowledge the need for an improved approach and also seek answers to my second query.
