Parse Cloud: Send Push to a single user

Question

I\'m using Parse and I can\'t make this method to work.

The idea is to send push to a single user with an already known user identifier from any platform within \'Cl

Answer 1

You can join Parse.Session and Parse.Installation with a user pointer as the Session primary key, next "installationId" as the join key.

var PushSend = function(payload, dbContact) {
    var querySession = new Parse.Query(Parse.Session);
        querySession.equalTo("user", dbContact);
        querySession.descending("updatedAt");

querySession.first({ useMasterKey: true })

.then(function(dbSession) {
    var installId = dbSession.get("installationId");

    var installQuery = new Parse.Query(Parse.Installation);
        installQuery.equalTo("installationId", installId);

        Parse.Push.send( {
            where: installQuery,
            data: {
                alert: payload
            }
        }, { useMasterKey: true} )

        .then(function() {
            // "success"
        }, function(error) {
            // "failed"
        } );
    }, function(error) {
        // "failed"
    } );
}

The above cloud function takes as arguments :

1. the payload text string
2. a destination contact pointer (you have for example previously queried from Parse.User)
