If you have to clear your cache on every deploy, you're doing something wrong.

@jelder yeah you're right, I added it for reference only, but you're totally right. I'm updating it.

Correct me if I'm wrong, but I believe you need to restart the app after running a database migration.

@dipth you're right. Otherwise you'll see forms that don't save. Thanks for the observation. I'm updating it again :)

Why not just use Heroku San?
