ActiveScaffold: AJAX-powered Rails scaffolding redux
AjaxScaffold was an early attempt to implement Rails' scaffolding features in an AJAXy way, providing a single-page interface for showing, editing, deleting, and sorting items from your Rails models. ActiveScaffold is the newest implementation of the concept, making AjaxScaffold obsolete. It includes RESTful API support, sorting, search, pagination, automatic handling of ActiveRecord associations, along with the features you were used to from AjaxScaffold. It's also guaranteed to work on relatively new versions of Firefox, Internet Explorer, and Safari.
