我在使用 gem 'remotipart'、'~> 0.4' 在 Rails 3.0.5 Ruby v 1.8.7 中上传 Ajax 文件时遇到问题。当我删除 if @asset.save? 时，我成功显示了警报？控制器中的语句，但是当它在那里时，不调用 js 文件。由于某种原因，资产没有被保存。

有任何想法吗？

控制器：

def create
  @asset = Asset.new(params[:asset])

  respond_to do |format|
    if @asset.save
      format.html
      format.js
    end
  end
end

看法：

<%= form_for @asset, :remote => true, :html => {:multipart => true}, :id =>             "new_asset_form" do |f| %>
    <%= render :partial => 'shared/error_messages', :locals => { :target => @asset } %>
    <%= f.hidden_field :company_id, :value => current_company.id %>
    <%= f.file_field :asset %> 
    <%= submit_tag 'Add', :class => 'submit' %>
<% end %>

创建.js.erb：

<%= remotipart_response do %>
  // Display a Javascript alert
  alert('success!');
  <% if remotipart_submitted? %>
    alert('submitted via remotipart')
  <% else %>
alert('submitted via native jquery-ujs')
  <% end %>
<% end %>

终端日志：

谢谢你的帮助。被困了好几个小时。
