有没有办法在ActiveAdmin中将索引传递给嵌套表单？

Question

有没有办法将index传递给activeadmin的嵌套表单部分？我的代码：

<% variant.has_many :variant_currencies, allow_destroy: true, heading: false, new_record: 'Add new price modifier' do |variant_currency| %>
  <% variant_currency.template.render partial: 'variant-currency-form', locals: { variant_currency: variant_currency, index: '??? how to pass it here ???' } %>
<% end %>

通常，如果我有迭代，我会像这样传递index： <% Post.each_with_index do |post, index| %>，但我怎么能告诉activeadmin，我希望在index声明中有has_many？谢谢。

你可以用老式的柜台做到......

<% counter = 0 %>
<% variant.has_many :variant_currencies, allow_destroy: true, heading: false, new_record: 'Add new price modifier' do |variant_currency| %>
  <% variant_currency.template.render partial: 'variant-currency-form', locals: { variant_currency: variant_currency, index: counter.to_s } %>
  <% counter += 1 %>
<% end %>
