Managing multiple environments of an app on Heroku with EGit

The next step is to manage multiple environments of an app such as dev/test/production. An entry proposes a solution. It's written in Japanese but developers can read it easily by following commands :D

Unfortunately it seems that EGit doesn't provide all the functions to deal with multiple environments.

If you want to execute a command from console, just attach "--app heroku-hello-world-staging" as follows:

heroku rake db:migrate --app heroku-hello-world-staging

heroku db:push --app heroku-hello-world-staging

Happy year end coding :)
