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:

Aaron intro

The cons to controller tests

If you’re not writing controller tests, what are you writing?
Get the code out of the controllers and test it in more isolation
Service objects

Rails
Cons of service objects
Using a service object inside of a controller
Pros of service objects
Getting smaller can happen step-wise

How writing his book impacted his views
Start small
And much, much more!
