This is for learning purpose only and for quick insecure applications. Use not on production sites.

This is a sample navigation menu that creates links to index files of all your active record models.

You can plug into your rails 3 application in a jiffy.

In your Gemfile

gem 'simple_nav'

In your application.css

*= require simple_nav

And in your layout partial:

<%= simple_nav %>

Use at your own peril!
