Getting paperclip to work with passenger not running under root

After moving from Thin to passenger to save memory on one of my VM (with only 256mb every byte counts… ) I could not get paperclip to re-size images.

This was the error I got:
[paperclip] An error was received while processing: #
[paperclip] Processing medium # in the thumbnail processor.
[paperclip] An error was received while processing: #

The problem was permissions on the rails tmp directory. When I deploy using Capistrano the RAILS_ROOT/tmp directory is cleared-out so the .ruby_inline setup is re-initialized by the root user. Since I don’t run Passenger as root this throws the error above. Here is how I get around this without logging in to the server after deploy and executing a chown command:

In my RAILS_ROOT/config/environments/production.rb file I added this to the bottom:

temp =‘ruby_inline’, ‘/tmp’)
dir = temp.path
Dir.mkdir(dir, 0755)

This replaced the old setup that I had:
ENV[‘INLINEDIR’] = File.join(RAILS_ROOT, ‘tmp’)

So now I delete the .ruby_rails directory with the wrong permissions and create a new directory with the rails user… nice!
