Method: ActiveStorage::Blob#key

Defined in:
activestorage/app/models/active_storage/blob.rb

#key ⇒ Object

Returns the key pointing to the file on the service that’s associated with this blob. The key is the secure-token format from Rails in lower case. So it’ll look like: xtapjjcjiudrlk3tmwyjgpuobabd. This key is not intended to be revealed directly to the user. Always refer to blobs using the signed_id or a verified form of the key.
