I am trying use a Java Uploader in a ROR app (for its ease of uploading entire directories). The selected uploader comes with some PHP code that saves the files to the server. I am trying to translate this code to Ruby, but am stumped on this point:

PHP has a very convenient superglobal – $_FILES – that contains a hash of all files uploaded to the current script via the HTTP POST method. It appears Ruby does not have a similar resource. Lacking that, what is the best way to access and save the uploaded files?

I am using the JavaPowUpload uploader ( http://www.element-it.com/OnlineHelpJavaPowUpload/index.html ).

    ruby on rails allows you use the application root directory to get at the file stored (wherever you have decided to put it) via #{RAILS_ROOT}.

    Check out this tutorial. Not the prettiest method, but it should give you an idea of what needs to be done. Once the file is uploaded, it’s just a matter of getting the right path and doing your processing from there.
