Cancel publish

[medihack]

Within the normal publish method there is an easy way to cancel the publish and return nothing (just use this.ready(); return;. With publishComposite this doesn't work. I get the following exception then: Exception from sub 2BgTTyL3mgoTmRtbL TypeError: Cannot read property 'children' of undefined.

How could I just cancel the publish (and publish nothing), for example when some provided parameter is invalid?

Ok, it seems a simple return {find: function() {}} solves the problem.

Would be great something like this.cancel() though..

@fpoirier1 You can simply return from a find function to accomplish that.

Yes, this is what I am doing right now :

var cancel = function(){
  return {find: function() {}}
}

Meteor.publishComposite('projects', function(){
  // Return nothing if user is not loggedIn
  if(!this.userId)
    return cancel();

    ...

I just tought it would have been cleaner that's all.

I discuss that scenario briefly in this blog post.

I get your point. Awesome work by the way!
