使用 ActiveMerchant 和 Rails 3 生成信用卡表格

Question

使用 Rails 3 我无法获得 ActiveMerchant::Billing::CreditCard.new 按预期工作的表单。

控制器

@credit_card = ActiveMerchant::Billing::CreditCard.new

视图

<%= form_for :credit_card, @credit_card do |f| %>
<%= f.text_field :first_name %>
<% end %>

错误

You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.any?

我在收到此错误时没有使用任何表单生成器。有没有不同的方法来做到这一点？
