Overview

Resource is the primary data storage for resource configuration in Active Admin

When you register a resource (ActiveAdmin.register Post) you are actually creating a new Resource instance within the given Namespace.

The instance of the current resource is available in ResourceController and views by calling the #active_admin_config method.
