I would like to copy a file from my computer to another specified path. The file has to be chosen by the user with a file_field and the destination is already hard-coded. How can I do that ? Thank you.

I'd use FileUtils::cp, but beware of path mangling via ../../<file>. For that, you can use expand_path and then check if the resulting path begin matches your jail.
