FriendlyId

FriendlyId is the "Swiss Army bulldozer" of slugging and permalink plugins for Ruby on Rails. It allows you to create pretty URL's and work with human-friendly strings as if they were numeric ids for Active Record models.

Using FriendlyId, it's easy to make your application use URL's like:

http://example.com/states/washington

instead of:

http://example.com/states/4323454

FriendlyId Features

FriendlyId offers many advanced features, including: slug history and versioning, scoped slugs, reserved words, custom slug generators, and excellent Unicode support. For complete information on using FriendlyId, please see the FriendlyId Guide.

FriendlyId is compatible with Active Record 2.3.x and 3.0.

rake db:migrate

# edit app/models/user.rb
class User < ActiveRecord::Base
