您如何救援I18n :: MissingTranslationData? [英] How do you rescue I18n::MissingTranslationData?

问题描述

我希望能够像这样挽救I18n::MissingTranslationData:

I want to be able to rescue I18n::MissingTranslationData like so:

begin
  value = I18n.t('some.key.that.does.not.exist')
  puts value
  return value if value
rescue I18n::MissingTranslationData
  puts "Kaboom!"
end

我尝试了上面的方法，但是它似乎并没有进入救援的范围.我只是在控制台上看到(由于puts):translation missing: some.key.that.does.not.exist.我从没见过Kaboom!.

I tried the above, but it doesn't seem to go into the rescue block. I just see, on my console (because of puts): translation missing: some.key.that.does.not.exist. I never see Kaboom!.

我如何使它工作?

推荐答案

IMO，这很奇怪，但是在i18n (0.5.0)的当前版本中，您应该传递一个要救援的异常:

IMO, it's pretty strange but in the current version of i18n (0.5.0) you should pass an exception that you want to rescue:

require 'i18n'
begin
  value = I18n.translate('some.key.that.does.not.exist', :raise => I18n::MissingTranslationData)
  puts value
  return value if value
rescue I18n::MissingTranslationData
  puts "Kaboom!"
end

，它将在将来的0.6版本中修复(您可以对其进行测试- https://github.com/svenfuchs/i18n )

and it will be fixed in the future 0.6 release (you can test it - https://github.com/svenfuchs/i18n)
