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

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 stupid 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
