Ember.JS - How to use multiple models, controllers and views in same page?

23
votes

I mostly understand the basics of Ember.JS. Most examples out there really just deal with a single controller and a model to show something on a page. I am really after building a full web app with Ember so can anyone tell me how do I organize and connect multiple controllers, models and views into a single page?

For example, if I navigate to /app/posts, I want to show a navigation-bar with bunch of things including some logged in information, a sidebar to search with a controller attached to it, a bunch of posts listed in the middle and maybe a twitter feed populated on the sidebar with a TwitterFeedController.

How do I connect a bunch of these together. What is the basic way to achieve "Sections" with their own controllers and models and views in Ember.JS?

I understand there's named "outlets". Current documentation doesn't seem to mention it past having a main {{ outllet }} in application template. I can't find the definition on their public API docs too (might be blind...).

Thanks in advance!
