Questions tagged [trailblazer]

Trailblazer is a thin layer on top of Rails. It gently enforces encapsulation, an intuitive code structure and gives you an object-oriented architecture.

Trailblazer gives you a high-level architecture for web applications. It extends the basic MVC pattern with new abstractions. Rock-solid conventions that go far beyond database table naming or route paths let you focus on your application code, minimize bugs and improve the maintainability.
