Instance Method Details

#additional_locale_routing_scopes ⇒ Object

def additional_locale_routing_scopes

def available_locales
  Blacklight::LocalePicker::Engine.config.available_locales
end

#current_page_for_locale(locale) ⇒ Object

Returns the url for the current page in the new locale. This may be overridden in downstream applications where our naive use of ‘url_for` is insufficient to generate the expected routes
