Active Storage Dashboard

Active Storage keeps your files, but Rails gives you no way to look at them. This
engine is that missing screen.

What you get

• Overview statistics for your Active Storage usage
• Browsable blobs, attachments and variant records
• File metadata, byte sizes, content types and checksums
• The record each attachment belongs to, linked
• No external dependencies — it ships its own assets

Mounting it

# Gemfile
gem "active_storage_dashboard"

# config/routes.rb
authenticate :user, ->(user) { user.admin? } do
  mount ActiveStorageDashboard::Engine, at: "/active-storage-dashboard"
end

Use a simple mount path without special characters.

Gate it

This reads every attachment in your application, so it belongs behind an admin
check. The README also carries a security advisory worth reading before you run the
bulk rake tasks on an un-upgraded Active Storage.
