Rails data migration—upload and process a folder

Question

I have hundreds of .txt files that need to be processed into a Rails db. This SO question talks about uploading and processing a single file, but I don't want to do that hundreds of times. Is there a way to upload a folder, then process each file within that folder?

Answer 1

As far as I know HTML5 Uploader supports uploading a directory but only Chrome has it implemented.
example HTML5 Uploader

If you are the only one doing the uploading, I would zip the file and handle unzipping it and iterating through the files on the Rails side. Note: if this will be a public interfece, you will have to be careful about sanitizing file names to prevent directory traversal attacks (e.g. '~/.ssh/authorized_keys').
