I use this code to upload photos, I find that it is not successfully upload photo, but other content can be updated. 

<% semantic_remote_form_for(@product, :html => {:multipart => true}) do |f| %>  
  <% f.inputs do %>  
    <%= f.input :title, :label => "Name" %>  
    <%= f.input :category , :include_blank => false , :label => "Category" %>  
    <%= f.input :price, :label => "Price" %>  
    <%= f.input :photo, :label => "Photo" %>
  <% end %>  
  <%= f.buttons %>  
<% end %>

The code from server log:

    I’m surprised it worked at all, since Javascript is not supposed to be able to upload files via AJAX. Was the new switch the fact that you made it a remote form for the product? Since even though it’s a gem helping with the semantic form building, even it shouldn’t be able to do file uploads in that fashion.
