I'm new to Heroku and Rails. I've recently deployed a simple project-
management site built on Michael Hartl's RailsTutorial sample app.
When I go to delete a user or a project, I encounter the "Heroku has a
read-only filesystem" error.
Could I please get enlightenment from the group on how to best deal
with this? Do I simply need to adjust some environment variables and
store stuff in /tmp? Is Heroku designed with the assumption that I'll
put my database on S3 and write/delete there rather than on Heroku?
Thanks!
