Hello, I need to be able to write a temporary file for use during the request only.
Locally I can use the following successfully:
tempfile = File.open(a.original_filename,'w') tempfile.write_nonblock(a.body) paperclip stuff........ tempfile.close
That works great, but not on Heroku... How can I do the above with Heroku's restrictions: http://docs.heroku.com/constraints#read-only-filesystem
I'm not understanding how to translate the above into: `#{RAILS_ROOT}/ tmp/myfile_#{Process.pid}`
Thanks for any help you can provide here.
