title: Ruby on rails file download using form submit
body: <p>I have a page where I upload a list of users to an action upload data. There on success/failure it lists me the list of invalid users. This is a one time action the lsit of users is not saved to database. I need to be able to write these user list to a file and allow the user to download this file. I do not have a clue on how to proceed. Any help would be appreciated.</p>
