High Quality Content by WIKIPEDIA articles! Hobo is an open source web application framework that builds on Ruby on Rails. It provides functionality that is commonly used on many websites (including user authentication and permissions, object lifecycles and ajax widgets) and tools that make existing Ruby on Rails features faster to develop and easier to use (including a powerful template engine, user-definable rich field types and automatic generation of database migrations, routing and controller actions) to make Ruby on Rails development even faster and more enjoyable for the developer.
