Defined in:
lib/active_storage_validations/asv_attachable_adapter.rb

Overview

Wraps a Rails attachable so callers do not repeat the type-dispatch case tree.

Must not be named Attachable: ActiveStorageValidations is included into Active Record, so include Attachable in an app model under this namespace would resolve to this class instead of the app's concern.

Supported representations: ActiveStorage::Blob, ActionDispatch::Http::UploadedFile, Rack::Test::UploadedFile, Hash, File, Pathname, and a signed blob id (String).

Defined Under Namespace

Classes: Base, Blob, FileLike, HashIo, Path, SignedId, Unsupported, Uploaded

Class Method Details

.filename_for(file) ⇒ Object

Filename for error options. Unknown types return nil (never raise). File / Pathname are always accepted here so a validation error can name the file even on Rails versions that cannot attach them.
