Environment Variables Discussion
I always found Env Variables very confusing, this does help. However still not a 100% sure if I'm use this method over something like Figaro.
Also how do I push these to Heroku?
Figaro and the new Rails 4.1 secrets.yml are ways to manage these. This episode is intented to explain what they are so when you run into things like Figaro and secrets.yml you have a better idea of what you're looking at.
Heroku has a config command that lets you view and set environment variables. More info here: https://devcenter.heroku.co...
