I suggest something like this 
https://github.com/andrew/24pullrequests/pull/343/files#diff-37c9b835927e3c363588f172de9bb6faR21

as homepage is a page of its own https://github.com/andrew/24pullrequests/blob/master/app/views/static/homepage.html.haml which I've extracted the variables from here https://github.com/andrew/24pullrequests/pull/343/files#diff-93df7b7ad210533b70a96d211e02fe52L2
