我们使用自己的异常处理程序来处理丢失的翻译：
# Logs missing I18n translations to `missing_translations.log`.
I18n.exception_handler = lambda do |exception, locale, key, options|
e = exception.respond_to?(:to_exception) ? exception.to_exception : exception
# log rotate, because it's not important enough to keep
@log ||= Logger.new(File.join(Rails.root, 'log', 'missing_translations.log'),2,5*1024*1024)
if e.is_a? I18n::MissingTranslationData
@log.info "#{locale}.#{key}"
else
raise e
end
exception.to_s
end
当我们的测试套件运行时，记录器的内容被保存到一个文件中，我们可以在其中查看是否缺少翻译。这非常有用，但通常并不清楚在哪里调用了丢失的键，因此可以修复它（例如在翻译通用键时）。遗憾的是我没有找到获取文件名和行号的方法，但我确定有解决方案吗？
我尝试了backtrace有关异常的方法，但这并没有提供更多信息。
[6] pry(main)> e
=> #<I18n::MissingTranslationData: translation missing: avatar.devise.failure.already_authenticated>
[7] pry(main)> e.to_exception
=> #<I18n::MissingTranslationData: translation missing: avatar.devise.failure.already_authenticated>
[8] pry(main)> e.to_exception.backtrace
=> nil
[9] pry(main)> e
=> #<I18n::MissingTranslationData: translation missing: avatar.devise.failure.already_authenticated>
[10] pry(main)> e.backtrace
=> nil
我也发现了这个，但这似乎已经过时了。
非常感谢您的帮助

使用caller我得到以下堆栈跟踪：
