$.Controller - jQuery plugin factory

JavaScriptMVC's controllers are many things. They are a jQuery plugin factory. They can be used as a traditional view, making pagination widgets and grid controls. Or, they can be used as a traditional controller, initializing and controllers and hooking them up to models. Mostly, controller's are a really great way of organizing your application's code.

Controllers provide a number of handy features such as:

Render and Redirect

The normal controller/view flow is to display a view template corresponding to the current controller action, but sometimes we want to change that. We use render in a controller when we want to respond within the current request, and redirect_to when we want to spawn a new request.

Render

The render method is very overloaded in Rails. Most developers encounter it within the view template, using render :partial => 'form' or render @post.comments, but here we'll focus on usage within the controller.

# RSpec's subject method, both implicitly and explicitly set, is useful for
# declaratively setting up the context of the object under test. If you provide a
# class for your describe block, subject will implicitly be set to a new instance
# of this class (with no arguments passed to the constructor). If you want
# something more complex done, such as setting arguments, you can use the
# explicit subject setter, which takes a block.
describe Person do
  context "born 19 years ago" do
    subject { Person.new(:birthdate => 19.years.ago }
