I am trying to be able to upload files with Sinatra. I have the code here, but I'm getting the error "method file_hash does not exist" (see /lib/mvc/helpers/helpers.rb).

What is going on here? Is there some dependency I'm missing.

I'm assuming you're trying to use paperclip with this. Could you paste your code again (link leads to a dead page)? Otherwise, what was your solution?
