The File field is the fastest way to implement file uploads in a Ruby on Rails app using Active Storage.
Avo will use your application's Active Storage settings with any supported disk services.

Deprecated options
The is_image, is_audio, and is_video options are deprecated in favor of letting Active Storage figure out the type of the attachment. If Active Storage detects a file as an image, Avo will display it as an image. Same for audio and video files.
