title: where can i find the class definition for action controller base?
body: <p>I am just a bit curious how application controller and action controller objects work in rails. Is there anywhere I can view the complete class templates for these objects? I was wondering if methods like "show" and "index" are just hook methods that are called inside the initialize of the object. Is this why we define our instance members from these? Are they basically just empty methods called in the init that will then define the instance variables as the objects are selected from the routes.rb file? </p>
