Most web applications have many more model objects exposed on the backend, or admin side, than they do on the front. Coding interfaces for all those models is redundant and a waste of resources when all you need is CRUD functionality that’s smart enough to handle all your ActiveRecord associations.

ActiveScaffold is a Ruby on Rails plugin that provides you with a wealth of dynamically created goodness, just plug the ActiveScaffold into your controller, you can have a AJAXified table interface for creating, updating, and deleting objects then. It has the following main features as well.

• Automatic handling of ActiveRecord associations
• Sorting, Search and Pagination
• Graceful JavaScript degradation
• RESTful API support (XML/YAML/JSON) baked in
• Sexy CSS styling and theming support
