Setting Up Your Development Environment The day-to-day business of writing Rails programs is pretty straightforward. Everyone works differently; here’s how we work.

Controllers orchestrate the application. Controllers receive events from the outside world (normally, user input), interact with the model, and display an appropriate view to the user.
For example, we may want to extend our application in the future to support users in many countries. In that case, we’d want to localize the display of the time, choosing a time appropriate to the user’s time zone. That would require a fair amount of application-level code, and it would probably not be appropriate to embed it at the view level. By setting the time to display in the controller, we make our application more flexible: we can change the time zone in the controller without having to report erratum • discuss Chapter 2.
