Inheritance Hierarchy of your Controller

In your Rails Application, if you want to get the Inheritance Hierarchy of your Rails Controller. Use this

Fire up the Rails console using

rails c

Then use

ApplicationController.ancestors - ApplicationController.included_modules

To get the Inheritance hierarchy of your Rails Application Controller.

To get the Inheritance Hierarchy of your own Controller use as

UsersController.ancestors - UsersController.included_modules

That's it.

The Output :

[ApplicationController, ActionController::API, ActionController::Metal, AbstractController::Base, Object, BasicObject]
