Uploadify + Paperclip + Rails nested before_save

Question

I need to create a model application form in which models can fill it out and add photos to it.

I follow this example using the Add, Clip, and Rails 3 methods. https://github.com/websymphony/Rails3-Paperclip-Uploadify

I have a polymorphic attachment model for images, and I would like to attach these loaded ajax attachments to the model's unsaved form, and there is a complicated part of cames there.

Users are not registered, so there is no "model_id" until it is saved.

Since I am showing the user a small preview of the images that he uploaded in ajax form after each upload, I need some way to correlate them.

I was thinking of some sort of middle token until the model is saved, but I'm not sure what the best approach is for this.

Thank!

We overloaded Uploadify when switching to Rails 3 and now use jQuery-File-Upload.

Setting up the middleware pool to do nothing more than downloading files seems to be a big problem.

The only problem with the jquery solution is that multiple downloads are not supported in IE.
