ruby-on-rails - rails 5 : Can you pluralize two words in a string with two different counts?

Question

我正在为列出产品评论摘要的商店构建 View 。我正在按分数对评论进行分组，我希望在每组顶部有一个字符串，形式为“10 条 5 星评论”。我知道如果我只想将“review”复数化，我可以在 en.rb 中做到这一点:

en: {
  reviews_header: {
    one: "1 review",
    other: "%{count} reviews"
  }
}

reviews_header 是否有格式？散列让我指定“评论”和“明星”的计数，以便在必要时将它们都复数化？在伪代码中，我想象的是:

en: {
    reviews_header: {
        counts: [ :review_count, :star_count ],
        review_count: {
            one: {
                star_count: {
                    one: "1 review with 1 star",
                    other: "1 review with %{star_count} stars"
                }
            },
            other: {
                star_count: {
                    one: "%{review_count} reviews with 1 star",
                    other: "%{review_count} reviews with %{star_count} stars"
                }
            }        
        }
    }
}

我会用 t(:reviews_header, review_count: 10, star_count: 5) 得到字符串.

我现在正在做的是将字符串更改为“10 条 5 星评论”的形式，这解决了“星级”复数的问题，但这在其他语言中不起作用。

这里有一个嵌套复数的情况。虽然我对 Ruby 的熟悉程度很初级，但我找不到任何文档可以通过 Ruby 的内置 i18n 功能为这种嵌套复数情况提供解决方案。但是，在支持 ICU Library 的编程语言中，有可能受益于 MessageFormat .

使用 this library对于 Ruby 的 MessageFormat 解析和格式化，可以手工制作一个嵌套的 MessageFormat 来覆盖这个字符串的所有变体，以覆盖任何语言中嵌套复数规则的复杂性。请记住，对于大多数语言，您不需要这些规则中的大部分，但很少有像阿拉伯语和俄语这样的语言需要许多这些情况；阿拉伯语有两个的特殊情况，俄语有一个特殊的情况(1, 21, 31, 1001，但不是 11)。可以找到来自 Unicode CLDR 项目的图表，其中列出了所有语言的复数规则 here .

通常，我训练翻译人员使用 this online tool (来自 message-format-rb 的同一开发人员)并根据他们的语言需要翻译 MessageFormat。



这是一个完整的、最大的 MessageFormat，后面是一个 Ruby 片段:

{review_count, plural, 
=0 {
    {star_count, plural,
        other {no reviews}}
}
zero {
    {star_count, plural,
        zero {{review_count} reviews with {star_count} stars} 
        one {{review_count} review with {star_count} star}
        two {{review_count} reviews with {star_count} stars}
        few {{review_count} reviews with {star_count} stars}
        other {{review_count} reviews with {star_count} stars}}
}
one {
    {star_count, plural,
        zero {{review_count} review with {star_count} stars}
        one {{review_count} review with {star_count} star}
        two {{review_count} review with {star_count} stars}
        few {{review_count} review with {star_count} stars}
        other {{review_count} review with {star_count} stars}}
}
two {
    {star_count, plural,
        zero {{review_count} reviews with {star_count} stars}
        one {{review_count} review with {star_count} star}
        two {{review_count} reviews with {star_count} stars}
        few {{review_count} reviews with {star_count} stars}
        other {{review_count} reviews with {star_count} stars}}
}
 few { 
    {star_count, plural,
         zero {{review_count} reviews with {star_count} stars} 
         one {{review_count} review with {star_count} star}
         two {{review_count} reviews with {star_count} stars}
         few {{review_count} reviews with {star_count} stars}
         other {{review_count} reviews with {star_count} stars}}
}
other {
    {star_count, plural,
        zero {{review_count} reviews with {star_count} stars}
        one {{review_count} review with {star_count} star}
        two {{review_count} reviews with {star_count} stars}
        few {{review_count} reviews with {star_count} stars}
        other {{review_count} reviews with {star_count} stars}}
}
}

和 Ruby 片段:

require 'message_format'
require 'test/unit/assertions'
include Test::Unit::Assertions

icumf = "{review_count, plural, =0 {{star_count, plural,other {no reviews}}} zero { {star_count, plural, zero {{review_count} reviews with {star_count} stars} one {{review_count} review with {star_count} star} two {{review_count} reviews with {star_count} stars} few {{review_count} reviews with {star_count} stars} other {{review_count} reviews with {star_count} stars}}}one {{star_count, plural, zero {{review_count} review with {star_count} stars} one {{review_count} review with {star_count} star} two {{review_count} review with {star_count} stars} few {{review_count} review with {star_count} stars} other {{review_count} review with {star_count} stars}}} two {{star_count, plural, zero {{review_count} reviews with {star_count} stars} one {{review_count} review with {star_count} star} two {{review_count} reviews with {star_count} stars} few {{review_count} reviews with {star_count} stars} other {{review_count} reviews with {star_count} stars}}} few {{star_count, plural,zero {{review_count} reviews with {star_count} stars} one {{review_count} review with {star_count} star} two {{review_count} reviews with {star_count} stars} few {{review_count} reviews with {star_count} stars} other {{review_count} reviews with {star_count} stars}}} other {{star_count, plural, zero {{review_count} reviews with {star_count} stars} one {{review_count} review with {star_count} star} two {{review_count} reviews with {star_count} stars} few {{review_count} reviews with {star_count} stars}        other {{review_count} reviews with {star_count} stars}}}}"

# Set the locale to get the plural rules for that locale
message = MessageFormat.new(icumf, 'en')
assert_equal message.format({ :review_count => 0, :star_count => 0 }), 'no reviews'
assert_equal message.format({ :review_count => 0, :star_count => 100 }), 'no reviews'
assert_equal message.format({ :review_count => 1, :star_count => 2 }), '1 review with 2 stars'
assert_equal message.format({ :review_count => 2, :star_count => 5 }), '2 reviews with 5 stars'
