Html表单不包括在post'；s参数文件数据

出于我甚至猜不到的原因，我的rails应用程序不再工作了。我没有改变rails代码中的任何内容，所以我想可能是关于浏览器的

简单表单，由简单表单生成：

<%= simple_form_for @order, :url => fillparameters_order_path(@order), :remote => true do |f| %>

  <%= f.association :aspectRatio,  collection: @order.project.aspect_ratios %>
  <%= f.input :client_email, :as => :string %>
  <%= f.input :soundtrack, :as => :file %>
  <%= f.input :project_id, :as => :hidden %>
  <%= f.button :submit %>
<% end %>

有什么想法吗，伙计们？

事实是：rails中的：remote=>true选项不能上传文件。有两种方法允许您使用AJAX进行文件上载：

rails方式：使用gem

Jquery方式：使用Jquery文件上传插件，有很多这样的插件，比如

等等
