After we explained to you what Service Objects in Rails is we’d like you to read this neat guide to Service Objects for Ruby on Rails. Creation and using in refactoring in details.
Rails follows a Model-View-Controller pattern. This raises questions around where programming logic should go once a Ruby on Rails application reaches a certain size. Generally, the principles are:

- Manage Many Service Objects with Modules;
- Testing. You will have existing unit tests for your code that you can move into a test file for your new Service Object;
- Extract Code to the Service Object;
- Guard clauses as a way of writing code.
The main aims are to follow the principles of clear responsibilities, modular design, and test-driven development to create a great app that is stable, maintainable, and extendable. Find some more tips that will help you here.
