mongodb - Selecting specific user data with meteor-presence

Question

Is it possible to retrieve specific user data (e.g. profile.name or even something else within profile object) with meteor-presence instead of returning userId? Or should I collect all userIds from Meteor.presences and then query Meteor.users with each userId to get the data I need?

Answer 1

Yes that is the best way to do it. You could use transform in your query too!

Meteor.presences.find({}, {transform:function(doc) {
        var user = Meteor.users.findOne({_id:doc.userId});
        if(user) doc.profile = user.profile;
        return doc;
    }
});

You can use this query in your template helper or pretty much anywhere else so that it now has a profile object to match the user. Make sure though all your users in your user collection are published in a safe way.
