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
