= EnumField

Macro to emulate a MySQL enum_field type thing - fork of giraffesoft/enum_field. It might be used instead of STI in some cases.

== Usage

This plugin encapsulates a validates_inclusion_of and automatically gives you a few more goodies automatically. That's it!

class Computer < ActiveRecord:Base
  extend EnumField
  enum_field :status, ['on', 'off', 'standby', 'sleep', 'out of this world']

  # Optionally with a message to replace the default one
  # enum_field :status, ['on', 'off', 'standby', 'sleep', 'out of this world'], :message => "incorrect status"

  #...
end

This will give you a few things:

• add a validates_inclusion_of with a simple error message ("invalid #{field}") or your custom message
• define the following query methods, in the name of expressive code:
  • on?
  • off?
  • standby?
  • sleep?
  • out_of_this_world?
• define the STATUSES constant, which contains the acceptable values
