has_enumeration 1.0.0

Extends ActiveRecord with the has_enumeration method allowing a symbolic enumeration to be stored in an ActiveRecord attribute. The enumeration is specified as a mapping between symbols and their underlying representation in the database. Predicates are provided for each symbol in the enumeration and the symbols may be used in finder methods. When using ActiveRecord 3, the symbols may also be used when interacting with the underlying Arel attribute for the enumeration. has_enumeration has been tested with Ruby 1.8.7, Ruby 1.9.2, JRuby 1.5.3, Rubinius 1.1.0, ActiveRecord 2.3.10, and ActiveRecord 3.0.1.
