How to deploy stage server in Rails and Heroku

Question

My Rails app is hosted on Heroku. I would like to have another server for staging (i.e., showing and testing new features) before updating my main app.

I have no idea how to do this in general, and in Rails.

How should I go about it? Do I need to create entirely new app, Git repository, Heroku server etc.?

What would be the most popular Gem for this kind of job? (I hear a lot about Caspitrano, but I don't know how it helps in context of Heroku).

Thank you very much for your help.

Heroku documentation is covered this case. You just need create another branch for staging. Check it https://devcenter.heroku.com/articles/multiple-environments
