Jen, hi. Maybe you have considered against it but one thing is to use
CarrierWave or Paperclip. It does save data to a model in the db but the
files store in the FS. But even if you dont, I think this should work if the
path is valid, as in my case it is just Paperclip providing the file path,
then just link to the controller action which provides this:
send_file @billing_run.tu_raw_bill_csv.path
