Come with me on a journey through the internals of Rails, as we trace a request from the web server to the controller action method, and follow the response back again. This will give you a glimpse of how Rails works under the hood, hopefully exposing some of the “magic” of the framework. We will also get to see some of the design/architectural decisions at the core of Rails.
This analysis was conducted against a newly generated Rails 5.0.0.1 app.
