Class Method Details

.available_locales ⇒ Array<Symbol>

Note:

The special case for Rails is necessary due to the fact that Rails may load the model before setting I18n.available_locales. If we simply default to I18n.available_locales, we may define many more methods (in LocaleAccessors) than is really necessary.

Returns available locales. Defaults to I18n.available_locales, but will use Rails.application.config.i18n.available_locales if Rails is loaded and config is non-nil.

Returns:

  • (Array<Symbol>) —

    Available locales
