数字的本地化(从法语语言环境到英语语言环境)在rails中不起作用

问题描述

我们知道法语数字与英语相比使用，"作为小数点分隔符.

As we know french numbers use "," as decimal separators as compared to english.

例如:英语:10.25％是 法语:10,25％

eg: English : 10.25% is French : 10,25%

我能够成功将英语数字翻译成法语:

I am able to successfully translate english numbers to french:

number_with_precision(121.45, locale: :fr)
#=> 121,45

但是我无法将法语数字翻译成英语:

But I am not able to translate french numbers to english:

number = number_with_precision(121.45, locale: :fr)
number #=> 121,45
number = number_with_precision(number, locale: :en)
number #=> 121,45

该数字仍保留在法国语言环境中.

The number remains in french locale.

这是我的en.yml:

This is my en.yml:

en:
  number:
    format:
      delimiter: ! ','
      separator: '.'
      significant: false
      strip_insignificant_zeros: false

这是我的fr.yml:

this is my fr.yml:

fr:
  number:
    format:
      delimiter: ! ','
      separator: ','
      significant: false
      strip_insignificant_zeros: false

我的翻译文件中是否有错误导致该错误?

Is there a mistake in my translation file which is causing this?

推荐答案

您正在做的英语到法语"不是来自英语". 121.45是Ruby数字文字，并且既不是英文也不是法语(尽管文字本身使用下划线表示分隔符，但英语本身也不像英文表示法那样使用小数点.)

What you are doing with what you consider as "English to French" is not "from English". 121.45 is a Ruby numeric literal, and is neither English nor French (although the literal itself uses a period for decimals like in the English notation although it uses underscore for delimiter, unlike English, which uses the comma).

在您所说的法语到英语"中，您正在传递法语格式的字符串.这就是为什么它不起作用的原因. number_with_precision应该如何知道所传递的字符串是用法语表示的?

In what you called "French to English", you are passing a string in French format. That is why it does not work. How is number_with_precision supposed to know that the string passed is written in French notation?
