FriendlyId

Modifies an ActiveRecord model such that an attribute other than id can be transparently used as a uri parameter.

Example

class User < ActiveRecord::Base
  friendly_id :username
end

User.find("rolandswingler") # => a User, (assuming that User exists)
User.find(1) # => still works as normal - you can still find by id

The urls generated for map.resources :user would be: /users/rolandswingler rather than /users/1

The attribute that you use as a friendly_id must exist and be unique - friendly_id generates the ActiveRecord validations for this.

TODO / LIMITATIONS

• You can't search by multiple friendly_ids: User.find("rolandswingler","fredbloggs") # won't work
• Your friendly_ids can't be purely numeric - they'll assumed to be standard ids.
