# heroku: multiple accounts/multiple environments

check ~/.heroku => credentials

heroku config:add RACK_ENV=staging --app foo-staging
heroku config:add RACK_ENV=production --app foo-production

## Deploy and migrate

You'll be doing this next command pretty often. We push the current branch to the staging server's master branch. Since this is the first deploy we'll need to do the same thing for production and run all the migrations.

git push staging master
git push production master

heroku rake db:migrate --app foo-staging
heroku rake db:migrate --app foo-production

heroku open --app foo-staging
heroku open --app foo-production


always add --app
