ClassyEnum 4.0 supports Rails >= 3.2.x and Ruby >= 1.9.3. If you want to use ClassyEnum >= 4.0, you will need to be running at least these versions.
ClassyEnum is no longer included in all Active Record classes and must be explicitly included in any Active Record classes you want to use it with.
class Alarm < ActiveRecord::Base classy_enum_attr :priority end
class Alarm < ActiveRecord::Base include ClassyEnum::ActiveRecord classy_enum_attr :priority end
serialize_as_json option has been removed in favor of overriding
#as_json in your enum subclasses.
See notes below if moving from 1.x to 3.x
In addition to some removing a few unnecessary methods, there are changes to how enum classes are defined. The
enum_classes macro has been removed in favor of inferring them from the subclass names. Subclasses must now follow a naming convention that uses the parent class as a namespace:
class Parent < ClassyEnum::Base enum_classes :child1, :child2 end class ParentChild1 < Parent end class ParentChild2 < Parent end
class Parent < ClassyEnum::Base end class Parent::Child1 < Parent end class Parent::Child2 < Parent end
Prior to 2.0, enum classes were implicity defined and were only required when overriding methods or properties. As of 2.0, all enum classes must explicity subclass a child of ClassyEnum::Base. If you used the generator, there are no changes to the existing structure.
Built-in Formtastic support has been removed. See the note at the bottom of this readme for more information how how to enable it.
