我有两个控制器可以修改一个大视图（carts / new.html.erb）。此视图呈现order_item / new.html.erb作为搜索结果传递@products的每个产品。这个功能很好。但是，当我单击为每个产品创建的表单的提交按钮时，这不起作用（仅适用于第一个产品），对于其他产品，它可以正常工作。所以，我看到生成的html和第一个表单标签没有生成。
缺少标记
<form accept-charset="UTF-8" action="/order_items" class="new_order_item" data-remote="true" id="new_order_item" method="post"></form>
谢谢！
