Controller Filters

The Rails REST implementation dictates the default seven actions for your controllers, but frequently we want to share functionality across multiple actions or even across controllers. Controller filters are the easiest way to do that.

Before, After, and Around

There are three types of filters implemented in Rails:

• a before_filter runs before the controller action
• an after_filter runs after the controller action
