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)

Answer 2

I am using the first of the two methods that you mentioned, and it works fine.

Just make sure that you use objectId and not the username for targetUser.id.

Ex:

targetUser.id = 'Qhao1j22j';   //Never hard code like this though.

Answer 3

This works well for me, but you have to link your users with your installations before:

var query = new Parse.Query(Parse.User);
query.equalTo('username', 'Sento');
// Find devices associated with these users
var pushQuery = new Parse.Query(Parse.Installation);
// need to have users linked to installations
pushQuery.matchesQuery('user', query);


Parse.Push.send({
    where: pushQuery,
    data: {
        aps: {
            alert: "Test",
            sound: ""
        }
    }
}, {
    success: function () {
        response.success("Hello world!");
    },
    error: function (error) {
        response.error(error);
    }
});
