How To Link Git Tag with Rails app

I use Git tags to manage the version numbers of my Rails apps.

Every time a new version is ready, I tag the current commit like this :

git tag -a v1.10 -m "FIXED PC-43/67/78"

I have created a ruby file in initializers which defines a constant to hold this information (in this case “v1.10”):

APP_VERSION = `git describe --always` unless defined? APP_VERSION

This constant simply contains the output of Git describe.
Now I can use it anywhere in my app where I would like to display the version number.
