Rails MVC

Rails MVC is the default Rails architecture bundle.

architecture :rails_mvc

This defines:

• controllers
• models
• helpers
• mailers
• jobs
• services

It checks that models and services stay away from controller and helper dependencies, and that they do not call controller-only APIs such as render, redirect_to, params, session, cookies, or flash.

The usual shortcut is:

preset :rails_way

Use preset :rails_strict when the app follows Zeitwerk naming and you also want cycle checks across the Rails components.
