Extracting Emoji From Slack!

Slack doesn't provide an easy way to extract custom emoji from a team. (Especially teams with thousands of custom emoji) This Gist walks you through a relatively simple approach to get your emoji out.

If you're an admin of your own team, you can get the list of emoji directly using this API: https://api.slack.com/methods/emoji.list. Once you have it, skip to Step 3

HOWEVER! This gist is intended for people who don't have admin access, nor access tokens for using that list.

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.
