= EnumField
Macro to emulate a MySQL enum_field type thing.
== Usage
This plugin encapsulates a validates_inclusion_of and automatically gives you a
few more goodies automatically. That's it!
class Computer < ActiveRecord:Base
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
