Rails 3 app, How to get GIT version and update website?

Question

I am deploying my rails 3 app using capistrano, and I want to get the git version (and date information) and update my website\'s footer with this.

How can I do this?

Answer 1

To people that doesn't use capistrano, a prettier one:

On config/initializers/git_info.rb:

GIT_BRANCH = `git symbolic-ref HEAD 2>/dev/null | cut -d"/" -f 3`
GIT_COMMIT = `git log --pretty=format:'%h' -n 1`
GIT_COMMIT_TIMESTAMP = `git log --pretty=format:'%ct' -n 1`

The second one gives the sha in prettier form (ex: 4df21c0).

The third one returns the UNIX TIMESTAMP, that I format using Time/DateTime later.
