== Rails 3 / Enum Support

Provides rudimentary enum support for Rails 3 model classes.

== Getting Started

1. Require the enum_support gem in each model class you wish to use it in: require 'enum_support'
2. Then, make sure to extend the module: Class IceCream < ActiveRecord::Base extend EnumSupport
3. Finally, specify as many enum attributes as you want within the class: enum :flavour, %w{vanilla chocolate strawberry neopolitan}

At this point, you can use your enumeration just as you would with any other attribute you specify: yum = IceCream.new yum.flavour = :chocolate yum.flavour # returns :chocolate

Validation is also performed when attempting to save a model instance. Setting an enum attribute to a value not in the initial set will render the instance invalid.
