field :cover_video, as: :file, direct_upload: true

Default value

false

Possible values

true, false

-> display_filename

-> lightbox

On the Show view, clicking an image opens it in an in-page lightbox. The lightbox previews the image, cycles through the field's other images with the arrow buttons or the ← and → keys, closes with Esc or a click outside the image, and links to the original file in a new tab. Non-image files keep their download link.

Set lightbox: false to render the image on its own.

field :cover, as: :file, lightbox: false

Default value

true

Possible values

true, false
