Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

Ubuntu 12.04, Ruby, Rails, Nginx, Unicorn and git-deploy

In the seemlingly endless search for the actual correct and easy way to deploy a Rails app, we have tried several ways. We tried out using Apache2 and running a cluster of Thin servers. With the built in threading of Puma we decided to use it with Nginx.

Server Setup

• Create new server
• Login to new server
  • ssh root@IPaddress (you can also use the domain name if you have the DNS setup already)
  • accept the RSA key

• Option: "None is a totally valid result, usually found in data structures"
  • unwrap(): YOLO use in prototyping
  • expect(...): to indicate the reason you believe None is impossible (or a contract violation for the method)
• Result: 😱 "Errors are unexpected but not bugs; the decision for how to handle them is up to the caller"
  • unwrap(): YOLO "I'm an app and don't know how to handle this error -- I'm fine if the whole process aborts"
  • try! / ?: "Leave the decision about how to handle this error to the caller; they have more information"
  • match / catch: "I'm going to handle the error right here right now"
• panic!: ☠ "The error is a bug and can't be recovered from. Game over man. Rust is allowed to abort the process if it wants"
