      • Model View Controller
      • Consider how the design of Ruby on Rails applications makes for well organized and easy to understand applications.
      • Sending E-mail
      • Send email from your application.
      • Testing
      • Test drive a new application feature using RSpec, Turnip, and Capybara. Distinguish unit tests from acceptance tests.

To maximize success, students should know basic programming principles like flow control, objects, methods, and data structures. Beginner programmers may find this class too difficult.

How to prepare your device for our class

Before class, please work through the Introduction of our Ruby on Rails book to install the required software.

Preparing in advance will save lots of class time!

Advice from the nerds

For students looking for some pre-reading, try Learn Ruby the Hard Way. It’s a short, fun approach to Ruby and might be helpful for those new to Ruby. For pre-class exercises, the Ruby Koans are great for learning and practicing Ruby. If someone works through them they will certainly be in a very good place for this course.
