Rails：引导模式中的分页

Question

我有一份产品清单。当用户点击产品时，会出现一个包含所有购买优惠的模式。如何将此购买优惠结果分页到模态中？ 最终目标是在模态中实现无限滚动（如 Twitter）。

关系：

1. Order has_many :buy_orders
2. BuyOrder belongs_to :product

Products.html.erb

<% @products.each do |product| %>
<button type="button" class='btn btn-primary' data-toggle="modal" data-target="#myModal_<%= product.id %>">
Show Product
</button>
<% end %>

 <!-- Modal -->
    <div id="myModal_<%= product.id %>" class="modal fade" role="dialog">
        <div class="modal-dialog">

        <!-- Modal content-->
          <div class="modal-content">
            <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal">&times;</button>
            <h4 class="modal-title text-left">BuyOffer</h4>
            </div>

            <div class="modal-body">

          <% product.buy_offers.each do |buyoffer| %>
            <%= buyoffer.total %>
          <% end %>

            </div>
          </div>
        </div>
    </div>

Answer 1

你可以使用will_paginategem来实现这个

<% product.buy_offers.each do |buyoffer| %>
     <%= buyoffer.total %>
 <% end %>

将上面的代码替换为

   <% buyoffers = product.buy_offers.paginate(page: params[:page], :per_page => 10) %>
      <% buyoffers.each do |buyoffer| %>
        <%= buyoffer.total %>
      <% end %>
   <%= will_paginate buyoffers %>
