So I can download the file and nothing happens. But when I manually refresh the page, boom! Interval checking kicks in and detects the cookie. Yes, I got it working! Great answer, thanks very much!

Let me know if you can't move your file to public folder. Improve this answer. I'm pretty sure all resources should be placed in the assets folder since rails 3 but since it worked it will do for now.

Sorry it was not specified which version of rails you were using — felipeclopes. Check the new edit I just made for Rails 3. Hope it helps you!

No need for this approach if those pdf's are available to everyone. With Rails 3. Navi I tried your approach but I keep getting the No route matches error. Can you see the issue here? How would you adjust this for multiple files? IE a folder of files one was generating links to in a list — Btuman. Show 1 more comment. If the files are static meaning they don't change , place them in the public folder.

I only want to set the filename, rather than redefine the whole action. I guess the thing is you're requesting a URI with a format. I would expect it to return a document with that name. Did you see my other suggestion? Grant Neufeld Grant Neufeld 1 1 gold badge 9 9 silver badges 16 16 bronze badges.
