# 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 <tt>has_one/many_attached :thingy, dependent: false</tt>, so that destroying
# any one record won't destroy the blob as well. (Then you'll need to do your own garbage collecting, though).
# but it is possible to associate many different records with the same blob. A foreign-key constraint
# on the attachments table prevents blobs from being purged if they’re still attached to any records.
