Directory to store cached files in Rails?

Question

I am generating some large files in my Rails application. Fortunately, they only need to be generated once. I would like to save these files to disk so that I don't have to generate them again.

Which directory in my Rails application is the most appropriate place to put application generated files?

Thanks!

If security of the files is not an issue you can put them in a subdirectory of public (for example, public/assets) which in your deploy script is symlinked to a directory in shared/public so that when you redeploy the files are retained.

If security is an issue, the solution is similar, though you would not want the directory to be web accessible. Instead you would use a controller to control access and serve up the files with send_file.
