Ruby on Rails

Hey there,

so I've just started to learn Ruby on Rails. I actually managed to
create an simple, one-line-plain-text app and deploy it on Heroku.

The app is supposed to be an image uploading website, but instead of
storing the images on the filesystem, I want them to be cURL'ed to an
image hoster's API.

There are a few major problems..

- I have just started with Ruby on Rails and I've never even touched
MVC
- Storing files on the filesystem is not allowed.

Is there any way to send (uploaded) files via cURL without even
temporarily storing them on the filesystem?

I'd be grateful for any newbie-friendly advice.

Thanks! :)
