module ActiveComponent

This is an autoincluded module for ActionController::Base

It will store the controller context for the given request in a @@controllers hash.

It was necessary to remove the controller instance from the @@controllers hash manually using ObjectSpace to prevent memory leaks in the server.

You can call ActiveComponent.get_controller from anywhere in the application.

This provides a method camelize and constantize

Autoinclude some of the modules from the controller top level

This provides a clean implementation for rendering your template inside your view.

<%= render_component(:view, var: var) %>

In addition to that you can render a collection of components using the same helper method

<%= render_component(:view, collection: views, as: :view)%>

The :as argument helps you to provide the instance variable name that you defined int your component class and it will be received like that.
