What's this?

representation(transformations) public

Returns an ActiveStorage::Preview for a previewable blob or an ActiveStorage::Variant for a variable image blob.

blob.representation(resize_to_limit: [100, 100]).processed.url

Raises ActiveStorage::UnrepresentableError if the receiving blob is neither variable nor previewable. Call ActiveStorage::Blob#representable? to determine whether a blob is representable.

See ActiveStorage::Blob#preview and ActiveStorage::Blob#variant for more information.
