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

To keep the internationalization similar as any other attribute I followed the nested attribute way as you can see here.

If you have a class User:

class User < ActiveRecord::Base
  enum role: [ :teacher, :coordinator ]
end

And a yml like this:

pt-BR:
  activerecord:
    attributes:
      user/role: # You need to nest the values under model_name/attribute_name
        coordinator: Coordenador
        teacher: Professor

You can use:

User.human_attribute_name("role.#{@user.role}")
