Overview

This action class helps to setup a new rails applicaton

Design Contraints

  • The workflow of this class should be easy to read. Hence helper methods are sourced out to helper modules.

  • All modifications of the @app_hash must be done within this file not in a helper module. This helps to easily grasp the app_hash structure with all changed made to it.
