Hope this helps and I am not sure it’s the best way but this is how I do it from routes to components and other routes.
/someRoute.js/
export default Ember.Route.extend({
afterModel: function(){
this.set('riverClass','move-1 step-1');
this.container.lookup('component:river-state').set('riverClass','move-1 step-1');
},
actions: {
didTransition: function(){
this.container.lookup('component:time-remaining').initTimer(5.0);
}
}
});
