Ruby on Rails Global ActiveRecord::Enum

Question

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

Answer 1

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
