Ruby on rails 当相应的语言文本不可用时，如何使用英语文本'；不存在

我有这样的文字

录制您的语音

——代码的大写左侧

当相应的日语文本失败时，如何使用“录制您的语音？”文本。

答案已给出

在application.rb文件中，您有以下选项：

# rails will fallback to config.i18n.default_locale translation 
config.i18n.fallbacks = true

# rails will fallback to en, no matter what is set as config.i18n.default_locale 
config.i18n.fallbacks = [:en]

# fallbacks value can also be a hash - a map of fallbacks if you will
# missing translations of es and fr languages will fallback to english
# missing translations in german will fallback to french ('de' => 'fr')
config.i18n.fallbacks = {'es' => 'en', 'fr' => 'en', 'de' => 'fr'}

# rails will fallback to config.i18n.default_locale translation 
config.i18n.fallbacks = true

# rails will fallback to en, no matter what is set as config.i18n.default_locale 
config.i18n.fallbacks = [:en]

# fallbacks value can also be a hash - a map of fallbacks if you will
# missing translations of es and fr languages will fallback to english
# missing translations in german will fallback to french ('de' => 'fr')
config.i18n.fallbacks = {'es' => 'en', 'fr' => 'en', 'de' => 'fr'}
