⚠️ Breaking Changes

None! This is a backwards-compatible enhancement.

🔄 Migration

From manual file upload implementation:

  1. Remove helper change functions:

    # Remove this:
change fn changeset, _ ->
case Ash.Changeset.get_argument(changeset, :avatar) do
 nil -> changeset
 path -> Ash.Changeset.change_attribute(changeset, :avatar_path, path)
end
end

  2. Add field declaration:

    field :avatar do
type :file_upload
opts upload: [cloud: MyApp.Cloud]
end

  3. That's it! Everything else is automatic.

📝 Notes

  • File uploads now work seamlessly with Ash actions
  • No manual storage logic required
  • Existing file preview only shows in update forms with existing data
  • Cascaded deletion requires cloud module configuration
  • Test failures (16 of 125) are pre-existing Phoenix LiveViewTest limitations with render_upload in nested LiveComponents - not implementation issues

🎯 Future Enhancements (Backlog)

  • Direct-to-S3 presigned URLs for large files
  • Automatic orphaned file cleanup task
  • Image cropping/resizing UI
  • File metadata storage in separate database attribute
