I really like Rails 4 new Enum feature, but I want to use my enum
enum status: [:active, :inactive, :deleted]
in every model. I cannot find any way how to declare for example in config/initializes/enums.rb and include every model
I'm very new in Ruby on Rails and need your help to find solution
Use ActiveSupport::Concern this feature created for drying up model codes:
#app/models/concerns/my_enums.rb
module MyEnums
extend ActiveSupport::Concern
included do
enum status: [:active, :inactive, :deleted]
end
end
# app/models/my_model.rb
class MyModel < ActiveRecord::Base
include MyEnums
end
# app/models/other_model.rb
class OtherModel
include MyEnums
end
I think you could to use a module containing this enum then you can include in each module you want to use:
# app/models/my_enums.rb
Module MyEnums
enum status: [:active, :inactive, :deleted]
end
# app/models/my_model.rb
class MyModel < ActiveRecord::Base
include MyEnums
end
# app/models/other_model.rb
class OtherModel
include MyEnums
end
<module:MyEnums>': undefined method enum' for MyEnums:Module (NoMethodError)
enum class macro available only in ActiveRecord.
