       <% PaymentGateway.all.each do |payment_gateway| %>
         <%= check_box_tag "rfp[payment_gateway_ids][]",payment_gateway.id, @rfp.payment_gateway_ids.include?(payment_gateway.id), :id => dom_id(payment_gateway) %>
          <%= label_tag dom_id(payment_gateway), payment_gateway.name %><br>
<% end %>

   </div>

推荐答案

首先，PaymentGateway.all是一个坏主意。这不应该出现在视图中，但是从一个实例变量控制器加载。请改变这一点。

First of all, PaymentGateway.all is a bad idea. This shouldn't be there in the view but loaded from the controller in an instance variable. Please change that.

这样做将是定义一个属性，让我们说，一个办法ADDITIONAL_INFO：

One way to do that would be to define a attribute, let us say 'additional_info':

<% PaymentGateway.all.each do |pg| %>
  <%= check_box_tag ..., onclick: "$('#{pg}_info').show(); $('#{pg}_info').siblings().hide();" %>
  ...
<% end %>

<div class="additional_infos">
  <%= f.input :gateway1_info, label: "Gateway" ... %>
</div>
