处理Ajax上传的最佳方法？

form_for @model, :remote => true, :html => {:multipart => true } does not allow us to send file via ajax.

I have found this but it's not up to date and it relies on dependancies :

• http://www.williambharding.com/blog/rails/rails-ajax-image-uploading-made-simple-with-jquery/

Anyone with up to date ressources ?

This is example for uploading File on Rails 3 using Jquery.

Make use of it, it is simple

I've used Uploadify in a recent application http://www.uploadify.com/ Some Rails specific notes here http://railstips.org/blog/archives/2009/07/21/uploadify-and-rails23/ I know you said Rails 3, but the concepts are the same.
