Question

I have to add more currencies to the app like on this web app http://www.designconnected.com/ as you can see, it converts the price in whatever currency you select and keep it this way. I ve been looking for gems that are out of date already, tutorials couldn t find any and in stackoverflow there are a few questions about it but none of them got what I need.

if any of you know a better gem, recently released... please let me know. or if there is no gem for it, should I add a currency_id to current_user so the app will show the proper currency for this user.. but then where do I take the currency rates from.. I ve been looking for a solution for 3 days now and nothing.

感谢您提供的任何建议。

Please help with some ideas on how to get it started if there is no way to find/get a full tutorial about this. Thank you.

和这是前进的道路。它不是我所问的,也不是问的,而是我现在最接近的答复。这是我完成这项工作的几个步骤:

http://www.ohchr.org。

gem "json" #if you don t have it
gem "money"
gem "google_currency"

在<条码>上创建文件 money.rb。

require  money 
require  money/bank/google_currency 
require  json 
MultiJson.engine = :json_gem
Money.default_bank = Money::Bank::GoogleCurrency.new

载于product.rb (或您有哪一种模式需要转换价格)

composed_of :price,
    :class_name => "Money",
    :mapping => [%w(price price), %w(currency currency_as_string)],
    :constructor => Proc.new { |price, currency| Money.new(price || 0, currency || Money.default_currency) },
    :converter => Proc.new { |value| value.respond_to?(:to_money) ? value.to_money : raise(ArgumentError, "Can t convert #{value.class} to Money") }

和观点文件:

<%= number_to_currency(product.price.exchange_to(:EUR)) %>

举例来说,我有一个信息技术局(意大利语),意大利货币现在为:欧元。

价格以欧元换算。该公司为我工作,用谷歌-货币计算,将价格从美元换算成欧元,而当地货币-ml文档则改变当地货币的货币,因此,你的价格为XXX,XX欧元,而不是XXX,XX美元。

为每个地方展示正确的货币,需要增加:

it:
  number:
    currency:
      format:
        format: "%n %u"
        unit: "EUR"

在<代码>t.yml文档中,或在贵国有货币的其他语文中,

你们可能不需要一刀切。你们可以直接呼吁,利用在这里解释的URL s,在你的法典中的任何时刻, go光银团。这可以在你的模式中或直接通过日本宇宙航空研究开发机构进行。
