不能用money-gem在ruby中输出货币

Question

如果我运行此代码：

require "money"

price1 = Money.new(100)
price2 = Money.new(2000)

total = price1 + price2

puts total

我收到I18n::InvalidLocale错误：

[path to ruby]/gems/i18n-0.7.0/lib/i18n.rb:284:in `enforce_available_locales!': :en is not a valid locale (I18n::InvalidLocale)

我该怎么做才能避免这个问题？

Answer 1

money gem使用I18n。您可以添加有效的区域设置或禁用I18n：

require 'money'

Money.new(100).format  #=> I18n::InvalidLocale: :en is not a valid locale

Money.use_i18n = false

Money.new(100).format  #=> "$1.00"

Answer 2

试试这个：

require "money"

price1 = Money.new(100)
price2 = Money.new(2000)

total = price1 + price2

puts "#{total.fractional} #{total.currency}"

Answer 3

require "money"

price1 = Money.new(100)
price2 = Money.new(2000)

total = price1 + price2

puts "#{total} #{total.currency}"
