• You can set the option to true for using default locale as fallback, like so:

config.i18n.fallbacks = true
  • Or you can set an array of locales as fallback, like so:

config.i18n.fallbacks = [:tr, :en]
  • Or you can set different fallbacks for locales individually. For example, if you want to use :tr for :az and :de, :en for :da as fallbacks, you can do it, like so:

config.i18n.fallbacks = { az: :tr, da: [:de, :en] }

#or

config.i18n.fallbacks.map = { az: :tr, da: [:de, :en] }
