What happens with Rails ends and our custom business logic begins? Many of us begin writing "service objects", but what exactly is a service object? How do we break down logic within the service object? What happens when a step fails? In this talk, we'll go over some of the most common approaches to answering these questions. We'll survey options to handle errors, reuse code, organize our directories, and even OO vs functional patterns. There isn't a perfect pattern, but by the end, we'll be much more aware of the tradeoffs between them.
