When you have multiple heroku apps, for one repo, you're going to need a hero! hero production run rake db:migrate

hero.fish

function __hero_get_remote_names
  git config --get-regexp 'remote.*.url' heroku.com | sed -E 's/^remote\.([^\.]*)\.url .*$/\1/'
end

function __hero_heroku_app_for
  git config --get remote.$argv[1].url | sed -E 's/^[email protected]:([^.]*)\.git/\1/'
end

function __hero_completion
  __hero_get_remote_names $argv[1]
end

function hero
  set APP (__hero_heroku_app_for $argv[1])
  heroku $argv[2..-1] --app $APP
end

complete -f --command hero --arguments '(__hero_completion (commandline -cp))'
