如何在表单标签助手中传递i18n插值变量？

Suppose one has the following en.yml

假设有一个en.yml

#en.yml
en:
  activerecord:
    books:
       price: "Price in %{currency}"

Then one can do the following in a view

然后可以在视图中执行以下操作

<%= t :price, :scope => "activerecord.attributes.book", :currency => "USD"%>

and it will print "Price in USD".

它将打印“以美元计价”。

But I can't figure out how to pass the currency when this translation is in a form

但是,当这种翻译在表格中时,我无法弄清楚如何传递货币

# views/books/edit.html
f.label :price

understandably throws an I18n::MissingInterpolationArgument, but I can't figure out what the syntax might be to pass the missing argument

可以理解地抛出一个I18n :: MissingInterpolationArgument,但我无法弄清楚传递缺失参数的语法是什么

# views/books/edit.html
f.label :price, :currency => "USD"

does not work.

不起作用。

I would try:

我会尝试:

<%= f.label I18n.t(:price, :scope => "activerecord.attribute.book", :currency => "USD") %>
