Meteor - How to automatically remove a single item from a collection after a specific time period from within a server side method?

Question

I wrote a click. event which calls a method. This method pushes single items (InfoId) into the collection called userManagement. So these items are assigned to that user.

eventhandler:

Template.available.events({
"click .push": function(e) {
    e.preventDefault();
    var InfoId = this.InfoId;
    Meteor.call('pushInfo', InfoId);
}, });

And the method:

Meteor.methods({
  'pushInfo': function(InfoId) {
    if (this.userId) {
      userManagement.update({
          '_id': this.userId
        }, {
          $push: {
            'activeInfos': InfoId
          }
        } 
      );
    }
  }
});

However, now I need to automatically remove exactly this previously added single item (InfoId) from 'activeInfos' after a specific time period e. g. three months.

Is there any way to do that?

Answer 1

for doing this you can use cronjob just install it using meteor add percolate:synced-cron

in cron you need to do two things one is add a task to cron, second is start our cron.

SyncedCron.add({
  name: 'your cron name',
  schedule: function(parser) {
    // parser is a later.parse object
    return parser.text('every 2 hours');
  },
  job: function() {
    console.log("hello");
  }
});

here schedule: is use to set time and in Job: we will add code which we want to run after a time we added in schedule.

after this start your cron. for this add this

SyncedCron.start();

i hope this will help
