A Google Analytics mixin for an Ember application controller. Sends a page view whenever the currentPath (url) changes. Normalizes the page url for both history and hash location routers.

google_analytics_mixin.js

Ember.GoogleAnalytics = Ember.Mixin.create({

  trackPageView: function() {
    if(!Ember.isNone(ga)) {
      Ember.run.next(function() {
        var loc = window.location,
            page = loc.hash ? loc.hash.substring(1) : loc.pathname + loc.search;
        ga('send', 'pageview', page);
      });
    }
  }.observes('currentPath')

});
