Extending ActiveRecord

Be default you should extend each ActiveRecord model manually by including TranslateEnum module in it. You can extend ActiveRecord by requiring translate_enum/active_record in initializer or inside yout Gemfile:

Gemfile:

gem 'translate_enum', require: 'translate_enum/active_record'

Initializer:

# config/initializers/translate_enum.rb
require 'translate_enum/active_record'

Advanced options

class User < ActiveRecord::Base
  enum gender: [:male, :female]
  
  translate_enum :gender do |tr|
    tr.i18n_scope = 'activerecord.attributes'
    tr.i18n_key = 'gender_list'
    tr.enum_klass_method_name = 'genders'
    tr.enum_instance_method_name = 'gender'
    tr.method_name_singular = 'translated_gender'
    tr.method_name_plural = 'translated_genders'
  end
  
  # Or even provide your own logic
  def self.translated_gender(key)
    I18n.t(key, scope: 'global.gender_list')
  end
end
