Unable to schedule push notifications - always firing immediately

[joeybenenati]

Issue Description

I am unable to get scheduled push notifications to fire at the date/time specified in the push_time property using parse-server on node. No matter what time I specify, or what format (js Date object, ISOString, etc) it always fires the push immediately. I am receiving on iOS client.

Steps to reproduce

Please include a detailed list of steps that reproduce the issue. Include curl commands when applicable.

following Hector's post at https://www.parse.com/questions/push-to-local-timezone-from-cloud-code...

var query = new Parse.Query(Parse.User);
  return query.find().then(function(users) {
    var installQ = new Parse.Query(Parse.Installation);
    installQ.containedIn('user', users);
    return Parse.Push.send({
      where: installQ,
      push_time: '2016-08-29T12:00:00.00',
      data: {
        alert: alert
      }
    }, {
      useMasterKey: true
    }).then(function() {
      console.log('done');
    }, function(error) {
      console.log(error);
    })
  });

Expected Results

iOS client receives push notification at local lime specified in push_time 2016-08-29T12:00:00.00

Actual Outcome

iOS client receives push notification immediately

Logs/Trace

You can turn on additional logging by configuring VERBOSE=1 in your environment.

Push scheduling is not supported on parse-server and are not likely to be supported in a short future (for the same reason jobs scheduling is not supported). PR are welcome, as always.

[zhangxiao918]

could you tell us how to implement this function as scheduling push.

[flovilmart]

I'm not sure I'll be able to help with that, and also not sure we want to implement a scheduling engine at large at it implies many choices and it's likely not to work correctly in scaled environments.

[acinader]

There's really no need to put this functionality into parse-server as scheduling services already exist and choosing the right one for your environment is better than trying to build a good solution into parse-server.
You can use an existing scheduler like cron that can then call a cloud function to send your notifications.

In our case, we're on AWS Elastic Beanstalk, so it made sense to use AWS services to implement scheduling. We have a CloudWatch event that is scheduled to fire at a particular time twice a day. The event invokes a Lambda function that calls the cloud function. Rock solid.

Is there a reason to keep the "scheduling pushes" session on JS SDK documentation? As it is not being used anymore...

[aliasad106]

@flovilmart Is there a way we can use Heroku Scheduler for Scheduling push notifications ? Because I have used Heroku Scheduler for scheduling jobs. And every notification has different scheduled time. It's not a

[flovilmart]

We'd need to implement some kind of scheduling adapter, that would enable you to use the heroku scheduler. Also, we'd need to store the pushes according to the schedule.

How can i schedule my push using cloud post ?

My code
var msg = request.params.message;
var channel = request.params.channel;
var date = request.params.dateTime;

Parse.Push.send({
        channels: [channel],
        data: {
            alert: msg,
            badge: "Increment",
            sound: 'default'
        },
        push_time: new Date(date)
    },
    {
        success: function () {
            console.log('##### PUSH OK', channel, new Date(date));
        },
        error: function (error) {
            console.log('##### PUSH ERROR');
        },
        useMasterKey: true
    });
