Trailblazer Rails Architecture
2 likes176 views
The document introduces Trailblazer, a Ruby on Rails architecture that introduces new abstraction layers to help with code organization. It aims to gently enforce encapsulation and intuitive structure by providing clear guidelines for where different types of code belong. This helps address the complexity issue that can arise in applications larger than a simple blog. Trailblazer moves processing logic out of controllers and into separate operations, keeps models logic-less for persistence, and uses cells/decorators to organize views.
