Defined in:
app/models/upscale_proposal.rb

Overview

Tracks an embryonic ImageKit asset that has been processed (upscaled)
but not yet confirmed by the user. Created by ImageUpscaleWorker when
propose: true is passed; promoted to a permanent Image on confirm,
or deleted immediately on reject.

The +ik_asset+ column stores the raw ImageKit upload response (same shape
as Image#asset) so that +confirm_upscale+ can reconstruct a real Image
record without a second upload.

Instance Method Details

#delete_ik_asset! ⇒ Object

Delete the embryonic ImageKit asset. Silences errors so a missing/already-
deleted asset never prevents the proposal record itself from being cleaned up.

end

#ik_file_id ⇒ Object

Convenience readers for nested ik_asset fields (snake_case first, then
legacy camelCase fallback matching Image's own accessor pattern).
