Meteor v 1.0 and Iron:Router

Question

Is anyone else getting the following error from Iron-Router since upgrading Meteor to version 1.0?

Please post here if you know how to resolve this issue.

Answer 1

There was a non backwards-compatible change in the newest version of Iron Router. The migration guide says:

onRun and onBeforeAction hooks now require you to call this.next(), and no longer take a pause() argument. So the default behaviour is reversed. For example, if you had:

Router.onBeforeAction(function(pause) {
  if (! Meteor.userId()) {
    this.render('login');
    pause();
  }
});

You'll need to update it to

Router.onBeforeAction(function() {
  if (! Meteor.userId()) {
    this.render('login');
  } else {
    this.next();
  }
});

More information

In your case, the by-the-book fix would be to add this.next() at the end of onBeforeAction. However, you should rather use waitOn:

waitOn: function () {
  return Meteor.subscribe("userData");
}

That way, you can set a loadingTemplate which will appear while the userData subscription is loading.
