|FileUpload without Tempfile||Helmut Juskewycz||4/8/11 4:38 AM|
I am looking for a way to upload a file to Rails 3 app, but without
generating a temp file. Googling the issue gave me some insight in how
the file upload works. As I understand Rails creates a temp file when
the file size is larger than 20kb. Is there a way to change this limit
and avoid the temp file generation?
Another solution I was looking in was creating a Rack App and so avoid
the file generation, however, didn't work either. Same with a Sinatra
Btw. yes it is mandatory that the file is not saved and only kept in
memory for security reasons.

What you've discovered is that it's not really Rails or Sinatra that's
I think you'll need to dig down to that web server - app interface

Thanks for pointing out that it is in Rack. Brings me one step closer
to a solution.

Is it enough for /tmp to be something like tmpfs (ie non persistent) ?

Sorry, badly worded. I meant that it's happening at the interface between the web server and your app; in this case that's where Rack lives.

Thanks Fred for pointin to tmpfs, however, using tmpfs would also
allow that the file can be read by anyone with access

I tried to hack into Rack, however, so far I was not able to avoid
creating a tempfile.

That will prevent any other process to get hands on that file.
