Uploadify + Paperclip + Rails nested association before_save

Question

I need to create a model application form where models can fill it and add pictures to it.

I'm following this example with Uploadify, Paperclip and Rails 3 approach. https://github.com/websymphony/Rails3-Paperclip-Uploadify

To the pictures, i have an polymorphic Attachment model and i would like to attach those ajax uploaded attachments to the yet unsaved model form and there's is where the tricky part cames.

Users are not logged, so there's no "model_id" until is saved.

Since i'm showing the user a small preview of the images that he uploaded in the form by ajax after each upload i need some way to correlate them.

I was thinking about some middle token until the model is saved but i'm not sure whats the best approach to accomplish this.

Thank you!

We dumped Uploadify when moving to Rails 3 and are now using jQuery-File-Upload.

Setting up a bunch of middleware to do nothing more than upload files seems like a major hassle.

Only problem with the jquery solution is multiple uploads aren't supported in IE.
