Is there a Rails plugin or Ruby gem that offers similar functionality to Django's built-in Admin Page?

Reading about D开发者_如何学JAVAjango, I saw this: http://docs.djangoproject.com/en/1.1/ref/contrib/admin/#ref-contrib-admin - the fancy simple to use admin page that django can magically create for you.

Is there a plugin or gem offering similar functionality in Rails.

Are there any plans to make Rails do this for you in the future?

Check out ActiveScaffold, it has some really nice functionality for auto-creating a quick admin GUI
