Rails 3 Ajax文件上载remotipart gem失败

Question

I am having trouble with Ajax file uploading in Rails 3.0.5 Ruby v 1.8.7 using the gem 'remotipart', '~> 0.4'. I have success with the alerts showing up when I remove the if @asset.save? statement in the controller but when its there the js file isn't called. For some reason the assets are not being saved.

Any ideas?

Controller:

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

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

View:

<%= 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 %>

Create.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 %>

Terminal Log:

Thanks for any help. Been stuck for hours.
