How to update the content of Meteor.user().profile attributes?

Question

I have a button that supposed to decrease an attribute inside the user if it is pressed,

I want to decrease the annualLeave attribute when its pressed.

"profile" : {
        "annualLeave" : 14,
        "replancementLeave" : 0,
        "medicalLeave" : 7
    }
}

Here is my code to get the userID:

Session.set('getUserId', Al.findOne({_id: Session.get('appealId')}));
console.log(Session.get('getUserId').userID);

The appealId session has the _Id of the current item. inside the item the _Id of the user, in which the item belongs to is stored in userID.

After I get the userID, I use it to retrieve the annualLeave. Here is the code:

Session.set('userDetails', Meteor.users.findOne({_id: Session.get('getUserId').userID}));
console.log(Session.get('userDetails').profile.annualLeave);

until now, both console.log prints out the values successfully.

Now to final step, I want to decrease the annualLeave by 1 and then update the user information in the database,

here is my code (doesn't work):

Session.set('counter', Session.get('userDetails').profile.annualLeave - 1);
Meteor.users.findOne({_id : Session.get('getUserId').userID},{$set:{profile.annualLeave: Session.get('counter')}});

What am I doing wrong the last part?

You need to put the key in quotes if it's not at root level and you need to use the .update() method instead of .findOne()

Meteor.users.update(Session.get('getUserId').userID,
  { $set: { "profile.annualLeave": Session.get('counter') }});

You can also skip part of your use of Session by just decrementing the value:

Meteor.users.update(Session.get('getUserId').userID,
  { $inc: { "profile.annualLeave": -1 }});

Note that if you're only searching by _id you can just pass the value as the first parameter instead of an object.
