Attachments associate records with blobs. Usually that's a one record-many blobs relationship, but it is possible to associate many different records with the same blob. If you're doing that, you'll want to declare with has_one/many_attached :thingy, dependent: false
, so that destroying any one record won't destroy the blob as well. (Then you'll need to do your own garbage collecting, though).
