Overview
Namespaces are the basic organizing principle for resources within Active Admin
Each resource is registered into a namespace which defines:
* the namespaceing for routing
* the module to namespace controllers
* the menu which gets displayed (other resources in the same namespace)
For example:
ActiveAdmin.register Post, namespace: :admin
Will register the Post model into the “admin” namespace. This will namespace the urls for the resource to “/admin/posts” and will set the controller to Admin::PostsController
You can also register to the “root” namespace, which is to say no namespace at all.
ActiveAdmin.register Post, namespace: false
This will register the resource to an instantiated namespace called :root. The resource will be accessible from “/posts” and the controller will be PostsController.
