Class Method Details

.config! ⇒ Object

Prevents the app from breaking when a translation is not present on the default locale. It should search for translations in all supported locales

It needs to build a proper key value hash for every locale. So that a locale always fallbacks to itself first before looking at the default and then to any other. e.g

supported_locales = [:es, :de, :en]

# right
{ en: [:en, :de, :es], es: [:es, :en, :de] .. }

# wrong, spanish locale would fallback to english first
{ en: [:en, :es], es: [:en, :es] }

# wrong, spanish locale would fallback to german first instead of :en (default)
{ en: [:en, :de, :es], es: [:es, :de, :en] .. }
