how to keep old versions of attachment files

[Alain Ravet]

Hi all,

When you update (replace) the attachment associated to an AR object,
all the files (styles) associated to the old attachment are wiped-out
from the server.
Is there a clean way to keep those old files?

Usecase : images in emails.
We send notifications by emails and they include images (ex: users
avatars). If an image is updated at a later time on the server (ex: a
user changes his avatar), we don't want those emails to look broken
because the old images files don't exist anymore.


This behaviour is caused by the self.clean in Attachment.assign

file attachment.rb, line 74

def assign uploaded_file
...
self.clear <<<--------- erases the old files
...
end

I couldn't find an option nor a call back to change this behaviour.

TIA

Hi,

Thanks for the patch. I haven't had a chance to get around to checking
