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:
- Fail, loudly, if the DB does not yet exist.
- Load the DB schema if the current schema version (as determined by
bin/rails db:version) is
- Run DB migrations otherwise.
For a "normal" app that usually means it will run the DB migrations.
