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).
# File activestorage/app/models/active_storage/attachment.rb, line 20 def purge destroy blob.purge end
Synchronously purges the blob (deletes it from the configured service) and destroys the attachment.
# File activestorage/app/models/active_storage/attachment.rb, line 26 def purge_later destroy blob.purge_later end
Destroys the attachment and asynchronously purges the blob (deletes it from the configured service).
