New features for EnumerateIt

gistfile1.rb

# Feature1: Change enumeration value based on bang methods (available only 
# when passing true to the :create_helpers option)
class RelationshipStatus < EnumerateIt::Base
  associate_values(
    :single  => 1,
    :married => 2,
    :widow   => 3
  )
end

class Person
  include EnumerateIt

  attr_accessor :relationship_status

  has_enumeration_for :relationship_status, :create_helpers => true
end

person = Person.new
person.relationship_status = RelationshipStatus::SINGLE
person.relatioship_status # => 1
person.married!
person.relationship_status # => 2

# Feature 2: Allowing object's attribute to hold more than one value
# (useful when more than on option applies, like in forms with multiple
# checkboxes and so on)
class ContactType < EnumerateIt::Base
  associate_values(
    :email        => 1,
    :sms          => 2,
    :phone        => 3,
    :smoke_signal => 4
  )
end

class Person
  include EnumerateIt
  attr_accessor :contact_type
  
  has_enumeration_for :contact_type, :multiple => true
end

person = Person.new
# creates an alias for contact_type as contact_types (pluralized)
person.contact_types # => []

#can receive both an array or a string separated by commas or spaces
person.contact_types = [ContactType::EMAIL, ContactType::SMS] # or %w(EMAIL SMS) or "1,2" or "1 2", etc

person.contact_types # => [1, 2]

# for ActiveRecord instances, the values would be serialized to the database, probably as a string, but always returned as an array.

# Querying
# This scope would be automatically created and would accept a variable number of arguments, in any order. Gotta think more about that...
Person.with_contact_types(1,2)
