Rails: How to use i18n with Rails 4 enums

Question

Rails 4 Active Record Enums are great, but what is the right pattern for translating with i18n?

Answer 1

Yet another way, I find it a bit more convenient using a concern in models

Concern :

module EnumTranslation
  extend ActiveSupport::Concern

  def t_enum(enum)
    I18n.t "activerecord.attributes.#{self.class.name.underscore}.enums.#{enum}.#{self.send(enum)}"
  end
end

YML:

fr:
    activerecord:
      attributes:
        campaign:
          title: Titre
          short_description: Description courte
          enums:
            status:
              failed: "Echec"

View :

<% @campaigns.each do |c| %>
  <%= c.t_enum("status") %>
<% end %>

Don't forget to add concern in your model :

class Campaign < ActiveRecord::Base
  include EnumTranslation

  enum status: [:designed, :created, :active, :failed, :success]
end
