I used to use a very similar approach to James back about 2 years ago used
in combination with capistrano ceploys. Basically, a cap recipe, it writes
to a revision file on deploy that greps the git log.
Note I used this for bug fixing with users as I had the tell me what the
hash (or deploy date) was at the bottom of pages. Similar approach might
work for you.
nb: This won't work on heroku since you can't write to file system.
# Takes a grep of the git log, grabs the latest date and write it to the
revision file so
# you can see on the application which version of the app you're running
desc "Write current revision to app/layouts/_revision.rhtml"
task :publish_revision do
put(`git log | grep ^Date -m 1`,
"#{release_path}/app/views/layouts/_revision.html.erb")
end
