Assets without fingerprint with rails 4

Hi,

Rails 4 seems to don’t add asset file with original filename (eg:
test.jpg), But only fingerprint version (eg: test_hash.jpg). This is not
very cool for mailer. If I put an image_tag() into my mailer, then I
change
my image. The email sended lose the path to the image (because
fingerprint
change…)

Any option to re-add the original file ? Or the best pratice is to put
in
public this kind of assets ?

Juste find this

Don’t know if it’s a bug or nor…

Thanks

Also have this issue. Anyone can help with this?
