# This is where we monkeypatch rails to look at the rev-manifest.json file we make in `gulp rev`
|
|
# instead of doing it's normal cache busting stuff on the url.
|
|
# eg: instead of '/images/whatever.png?12345', we want '/dist/images/whatever-<md5 of file>.png'.
|
|
# There is a different method that needs to be monkeypatched for rails 3 vs rails 4
