Heroku Release Phase + Review Apps + Rails

This is a simplified, but fairly thorough, set of scripts and configuration to enable Heroku Release Phase for Rails apps. Further, this particular set up plays nicely with Heroku Review Apps in that the release phase script will:

1. Fail, loudly, if the DB does not yet exist.
2. Load the DB schema if the current schema version (as determined by bin/rails db:version) is 0.
3. Run DB migrations otherwise.

For a "normal" app that usually means it will run the DB migrations.

I am the owner of lvh.me. And I'm glad to hear it's helpful. In truth, it's just a fancy DNS trick. lhv.me and all of it's sub-domains just point back to your computer (127.0.0.1). That means running ssl is as simple (or difficult) as running ssl on your computer.

I'm not sure how comfortable you are with the command line, but here's my how I setup my development environment. (rvm, passenger, nginx w/ SSL, etc).

Install rvm (no sudo!)

------------------------------------------------------

bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head ) source ~/.rvm/scripts/rvm rvm install ree-1.8.7-2010.02
