i18n 多元化

问题描述

我希望能够在 Rails 中翻译 i18n 中的复数字符串.一个字符串可以是:

I want to be able to translate pluralized strings in i18n in rails. A string can be :

You have 2 kids

或

You have 1 kid

我知道我可以使用复数辅助方法，但我想将它嵌入到 i18n 翻译中，这样我以后不必在任何时候弄乱我的观点.我读到 :count 以某种方式用于复数的翻译，但我找不到任何关于它如何实现的真正资源.

I know that I can use pluralize helper method, but I want to embed this in i18n translations so that I don't have to mess up with my views at any point in the future. I read that :count is somehow used in translations for plural, but I can't find any real resources on how it gets implemented.

请注意，我知道我可以在翻译字符串中传递一个变量.我也尝试过类似的东西:

Notice that I know that I can pass a variable in a translation string. I also tried something like :

<%= t 'misc.kids', :kids_num => pluralize(1, 'kid') %>

效果很好，但有一个相同想法的基本问题.我需要在复数帮助器中指定字符串 'kid' .我不想这样做，因为它会导致将来出现视图问题.相反，我想保留翻译中的所有内容，而视图中没有任何内容.

Which works fine, but has a fundamental problem of the same idea. I need to specify the string 'kid' in the pluralize helper. I don't want to do that because it will lead to view problems in the future. Instead I want to keep everything in the translation and nothing in the view.

我该怎么做?

推荐答案

试试这个:

en.yml :

en:
  misc:
    kids:
      zero: no kids
      one: 1 kid
      other: %{count} kids

在视图中:

You have <%= t('misc.kids', :count => 4) %>

更新了多复数语言的答案(用 Rails 3.0.7 测试):

文件 config/initializers/pluralization.rb:

require "i18n/backend/pluralization" 
I18n::Backend::Simple.send(:include, I18n::Backend::Pluralization)

文件 config/locales/plurals.rb:

{:ru => 
  { :i18n => 
    { :plural => 
      { :keys => [:one, :few, :other],
        :rule => lambda { |n| 
          if n == 1
            :one
          else
            if [2, 3, 4].include?(n % 10) && 
               ![12, 13, 14].include?(n % 100) && 
               ![22, 23, 24].include?(n % 100)

              :few 
            else
              :other 
            end
          end
        } 
      } 
    } 
  } 
}

#More rules in this file: https://github.com/svenfuchs/i18n/blob/master/test/test_data/locales/plurals.rb
#(copy the file into `config/locales`)

文件 config/locales/en.yml:

en:
  kids:
    zero: en_zero
    one: en_one
    other: en_other

文件 config/locales/ru.yml:

ru:
  kids:
    zero: ru_zero
    one: ru_one
    few: ru_few
    other: ru_other

测试:

$ rails c
>> I18n.translate :kids, :count => 1
=> "en_one"
>> I18n.translate :kids, :count => 3
=> "en_other"
>> I18n.locale = :ru
=> :ru
>> I18n.translate :kids, :count => 1
=> "ru_one"
>> I18n.translate :kids, :count => 3
=> "ru_few"  #works! yay! 
>> I18n.translate :kids, :count => 5
=> "ru_other"  #works! yay!
