Access user/userId inside a function called by a publish

Question

I have a Meteor.publish in my code, that calls another function, that calls another one, and so on. Then, in the most inner function, I need to know what user is the active one.

Meteor.user() can't be used. It says

Meteor.userId can only be invoked in method calls. Use this.userId in publish functions.

and this.userId is not acessible inside the inner function.

What can be done then?

Answer 1

Can't you just assign this.userId to a variable within the publish method and then pass that variable around?

Meteor.publish("my_channel", function() {
  var userId = this.userId;
  myFunction(userId);
});
