如何使用 i18n & 配置语言环境别名导轨? [英] How to configure locale aliases using i18n & rails?

问题描述

我正在开发一个 Rails 应用程序 (3.2.13)，该应用程序被翻译成多种语言，包括挪威语(3 种可用风格之一).在公共页面上，该应用程序使用浏览器的语言设置来设置区域设置.

I am working on a rails app (3.2.13) that is being translated into several languages, including (one of the 3 available flavours of) Norwegian. On public pages, the app uses the browser's language settings to set locale.

大多数浏览器提供 3 个单独的挪威短代码:no、nb &nn.我们的翻译在 nb 中，但我认为最好是 no &nn 也默认为 nb.这样，如果用户的浏览器语言首选项设置为 no 然后是 en，应用程序将尝试首先提供 nb 挪威语，而不是跳过直接上英语.

Most browsers offer 3 separate Norwegian shortcodes: no, nb & nn. The translations we have are in nb, but I think it would be best if no & nn also defaulted to nb. That way, if a user's browser language preferences were set to no then en, the app would try to supply nb Norwegian first, instead of skipping straight to English.

是否可以为 i18n gem 配置一个语言别名"列表，像这样?

Is it possible to configure a list of "language aliases" for the i18n gem, something like this?

 config.i18n.available_locales = [:sv, :en, :nb, :da, :fi]
 config.i18n.aliased_locales = [:nb <= :no, :nb <= :nn]

推荐答案

简短回答

看看回退

在 initializers 中创建一个文件，如 i18n_fallbacks.rb

Create a file in initializers like i18n_fallbacks.rb

config.i18n.fallbacks = {:no => [:nb], :nn => [:nb]}

这里参考

相关事项

您甚至可以设置多个回退，它们将按照指定的顺序进行:

You can even set multiple fallbacks, and they will be taken in the same order as specified:

例如:

config.i18n.default_locale = :de
config.i18n.fallbacks = {:de => [:en,:es]}

de.yml

  :de:
    greeting: Hallo

en.yml

  :en:
    foo: bar

es.yml

  :es:
    bar: baz

您将获得以下信息:

I18n.t :greeting # found in de.yml, no fallback
# => 'Hallo'

I18n.t :foo # not in :de, try in :en and found
# => "bar"

I18n.t :bar # not in :de, try in :en and in :es
# => "baz"

I81n.t :other # not found anywhere, note the message delivers not found for the current locale:
# => "translation missing: de.other"
