In my application I would like the user to download a file that is
dynamically created from the database. Currently, I have rails put all
the text into one variable and then save that to a temporary file with a
filename that is generated from a sha1.
If a user requests a file, is there a way to automatically delete that
temporary file when it is done downloading or should I just set up a
Or, if you have any other suggestion on how to send a file to a user
there would be greatly appreciated.
