[Radiant] Access to dummy ActionController?

[Daniel Sheppard]

>From a behavior's process method, you've got access the same request and
response objects that and ActionController wants so you can pretty much
delegate completely to a controller:

class MyController < ApplicationController
  def initialize(behavior)
    @behavior = behavior
  end
  def some_action
    render :text => "My behavior says that my url is
#{@behavior.page_url}"
  end
end

class MyBehavior < Behavior::Base
  def process(request, response)
    MyController.new(self).process(request, response, :some_action)
  end
end

I'm doing this for the moment with my Commentable behavior, and it seems
to work, but haven't tested it fully yet.

Most of the functionality of a controller is provided by modules, so you
should be able to get most of what you want by including the various
ActionController modules.
