   1 # A simple exception handler that behaves like the default exception handler
   2 # but additionally logs missing translations to a given log.
   3 #
   4 # Useful for identifying missing translations during testing.
   5 #
   6 # E.g.
   7 #
   8 #   require 'globalize/i18n/missing_translations_log_handler
   9 #   I18n.missing_translations_logger = RAILS_DEFAULT_LOGGER
  10 #   I18n.exception_handler = :missing_translations_log_handler
  11 #
  12 # To set up a different log file:
  13 #
  14 #   logger = Logger.new("#{RAILS_ROOT}/log/missing_translations.log")
  15 #   I18n.missing_translations_logger = logger
