I just started learning Rails and haven't deployed yet, but the thought of upgrading after deploying a project scares me a lot.

  Why does it scare you? It's good to be wary of the upgrade process.. but this is why you have (I hope!) database backups and source control (as a minimum). Then at least you can roll back. Then it's just extras after that, test coverage, staging servers etc. etc. Anyway, upgrading is a fact of life once you're using a framework (unless you want to get hacked) so best to get used to it :) Good luck!

  I've found the best way to make upgrading easier is having good test coverage. I think one of the biggest fears when upgrading is having something break but not knowing that it is now broken. Although tests won't always catch everything they are a great start to ease the upgrade process.

  To have tests (and particularly integration tests) is a big help; as has already been mentioned. Another thing is to use staged deployments: dont deploy to production-env from you development-env, but to a staging-env (if possible using the same or a copy of the live database). Then have a look with some (possibly non-technical) humans if the app still behaves as expected. While it can be laborious for a large app, it should make a deployment to production a lot less scary. As mentioned by others: upgrading is part of running a web app that depends on popular libs.
