Ruby on rails 如何将与活跃商户链接的正常表单更改为Braintree dropin ui？

我有一个注册页面，用户将输入个人信息和信用卡信息。 此信用卡信息与activemerchant集成，并存储在数据库中

这是我的表格：

<%= semantic_form_for(@account, :url => account_create_path, :html => { :multipart => true, :class => 'billing'}) do |f| %>

   <div class="section section-first">
      <%= f.inputs :for => :user do |u| %>
        <h3>Account Information</h3>

        <%= u.input :name, :input_html => {:placeholder => "Name", :value => @account.user.name} %>
        <%= u.input :email, :input_html => {:placeholder => "Email", :value => @account.user.email} %>
      <% end %>
    </div>
        <div class="section">
            <%= f.inputs :for => :creditcard do |c| %>
            <h3>Credit Card Information</h3>
            <%= c.input :brand, :selected => @creditcard.brand.nil? ? "visa" : @creditcard.brand, :label => "Credit Card", :as => :select, :class => 'dropkick', :include_blank => false, :collection => Saas::Config.gateway == "bogus" ? [['Bogus', 'bogus']] : [['Visa', 'visa'], ['MasterCard', 'master'], ['American Express', 'american_express'], ['Discover', 'discover']] %>
            <%= c.input :number, :input_html => { :placeholder => "Card Number"}, :label => "Card Number", :as => :numeric %>

            <li class="select required" id="account_creditcard_expiration_input">
                <label for="account_creditcard_expiration">Card Expires On<abbr title="required">*</abbr></label>
              <%= c.select :year, (Time.now.year .. 10.years.from_now.year), :selected => @creditcard.year.nil? ? Time.now.year : @creditcard.year, :class => 'dropkick dd-small' %>
              <%= c.select :month, [['1 - January', 1], ['2 - February', 2], ['3 - March', 3], ['4 - April', 4], ['5 - May', 5], ['6 - June', 6], ['7 - July', 7], ['8 - August', 8], ['9 - September', 9], ['10 - October', 10], ['11 - November', 11], ['12 - December', 12]], :selected => @creditcard.month.nil? ? "1" : @creditcard.month, :class => 'dropkick' %>
            </li>

            <%= c.input :verification_value, :label => "CVV Code", :input_html => { :placeholder => "CVV Code", :value => @creditcard.verification_value,
                :type => "password",
                :class => 'short' } %>

          <% end %>

<% end %>

简单回答：你不能。这个插件是为了安全地替换您托管的信用卡表单。要使用Drop-in，您应该取出表单和帐户模型的整个信用卡部分，不要期望处理和存储信用卡数据，而是接收Drop-in返回的数据，并通过Braintree交易或支付方法API使用它

详细回答：该插件是一个由Braintree托管的预构建表单，我们将通过iframe将其插入页面上的表单中。当表单提交时，来自Drop-in的信用卡（或PayPal等）信息被发送到Braintree，支付方法nonce被返回到页面（通过JavaScript回调或插入表单中的隐藏字段）。nonce是一个随机生成的字符串，代表支付信息，并且可以在没有安全风险的情况下通过应用程序。查看Braintree开发者文档，了解更多详细信息和示例代码

这一切的主要原因是安全。在不安全的环境中存储信用卡信息违反了行业法规（称为PCI安全标准），存储信用卡的CVV/安全代码也违反了PCI法规。该插件（或我们的托管字段集成）使您更容易满足PCI标准，并减轻您保护站点的负担

总而言之：您应该从ActiveMerchant中删除客户信用卡的集成，而不将其包含在您的架构中。相反，在表单中包含一个空白div，以便插入插入插入，并在模型/控制器中插入插入返回时使用付款方法。如何将nonce、服务器端Braintree API调用及其结果集成到rails模型中取决于您。我们有一个完整的rails应用程序示例，它使用了下拉菜单：请随意查看braintree\u rails\u示例在braintree github页面上的repo以获取想法。

您是否尝试添加下拉列表？他们有一个沙箱和他们的文档：添加插件非常好。到目前为止，什么还不起作用？您是否尝试添加了临时登录？他们有一个沙箱和他们的文档：添加插件非常好。到目前为止什么还不起作用？
