Strategic - Painless Strategy Pattern in Ruby and Rails
Strategy Exclusion: exclude a strategy from a matcher (e.g. partial match on 'USA' and 'US', but not 'U') To give you some background, the Strategic Ruby gem was mostly born out of work I did last year at Chronogolf by Lightspeed, a golf course management web app built in Ruby on Rails, where we had countless of strategies for customizing models, especially in relation to quotes, pricing, payments, memberships, and golf course tee time reservations.

check out the `light-service` gem - it lets you create services that use this pattern and compose them into complex flows: https://github.com/adomokos/light-service

How to avoid if/else with different ramifications
Similar to the above recommendations of Railway Orientated Programming and the Interactor gem, I use the Light Service gem. While it can sometimes be a bit verbose it excels in code reuse, testability, and composition.

The Ruby Unbundled Series: Services vs. Objects - The Battle for Decomposition and Reuse
You can implement the service pattern as a PORO, but it helps to use one of the gems available to aid in code structure, orchestration, and error handling. The LightService gem provides a nice implementation without adding hardly any overhead. It’s design is very simple, as shown in the diagram below. An organizer is used to define the sequential workflow, which is made up of one or more actions. An error in any of the actions will short-circuit the entire workflow.
