Ruby on Rails i18n: storing locale names in their yml files and retrieving them.

en.yml

# config/locales/en.yml

en:
  i18n:
    language:
      name: 'English'

i18n.rb

# config/initializers/i18n.rb

module I18n

  def self.name_for_locale(locale)
    I18n.backend.translate(locale, "i18n.language.name")
  rescue I18n::MissingTranslationData
    locale.to_s
  end

end

# E.g.:
#   I18n.name_for_locale(:en)  # => "English"

+1 for the updated answer. thanks!

Exception I18n::MissingTranslationData not working
I'm getting "translation missing: en.i18n.language.name" instead of locale.to_s

@mcmegavolt just replace your code to smth like this

self.with_locale(locale) { self.t('i18n.language.name', raise: true) }
