This is an example of how I combine interaction/service classes with Wisper event broadcasting in Rails.

In this example, I show a UsersController#create API, a corresponding service object, and all the test code/listeners to make it all happen.

The outcome is:

• Concepts in your system ("Signing up a user", "Creating an order") have a single entry point in your codebase, vs. making raw ActiveRecord calls to object.save in dozens of places.
• Since your concept has one entry point (the service class), you can easily grep for usage of it.
• Stupid easy to attach listeners to the service class
• All event listeners are very small and easily unit tested
