In this episode of Ruby Rogues, the panel discusses removing business logic from Rails controllers with Aaron Sumner. Aaron is a long time Ruby developer, using mostly Rails, writes a blog called Everyday Rails, and most people know him from his book, Everyday Rails Testing with RSpec: A practical approach to test-driven development. They discuss service objects, the pros and cons of using them, and they emphasize not trying to change something all at once, but gradually.

In particular, we dive pretty deep on:
