Updating A Sub-document Through Meteor Methods Via A Click Function Proving Problematic

I have a button .toggle-addToSet that captures two integers, this.id which is the current posts' id, and setid (sid) which is an _id of a collection Set which the user has the abi

Solution 1:

You have an extra parameter in your addingSets method.

Currently you have addingSets: function(set, sid, ob) defined in the function.

When you're calling it from the client, you're doing it like so:

Meteor.call('addingSets', ob, sid, function(error, user) {...}

Notice that the function is expecting 3 parameters to be passed to it while you're giving it only 2. So in your case, ob gets mapped to set, and sid gets mapped to sid and since the 3rd param isn't being passed, it's undefined.

Helper:

Template.latestSingle.events({
  'click .toggle-addToSet': function(e, template) {
    var ob = this.id
    console.log(ob);
    var sid = $(e.currentTarget).data('setid');
    Meteor.call('addingSets', ob, sid, function(error, user) {
      console.log(ob)
    });
  }
});

Server:

Meteor.methods({

    addingSets: function(ob, sid) {
        console.log(sid);
        console.log(ob);
        Sets.update({
      _id: sid
    },
    {
      $addToSet: {

        ArticleId: ob
      }
    });
    }
});

The positions and the params passed are important.
