Sending uploaded file to resque worker to be processed

Question

I just started using resque to do some processing on some very large files in the background, and I'm having trouble figuring out how to pass a file to a resque worker. I use rails to handle the file upload, and rails creates an ActionDispatch::Http::UploadedFile object for each file uploaded from the form.

How do send this file to a resque worker? I tried sending a custom hash of just the pathname of the temporary file and original filename, but I can't reopen the temporary file in the resque worker anymore (just a normal Errno::ENOENT - No such file or directory) because rails seems to delete that temporary file after the request ends.

Http::UploadedFileisn't accessible once the request finishes. You need to write the file somewhere (or use s3 as temp storage). Pass resque the path to the file that you wrote.
