Module: FileDownloadPresenter

Included in:
Controllers::WarehouseStreamActions, FileDownloadsHelper
Defined in:
app/concerns/file_download_presenter.rb

Overview

Resolves a download URL into display metadata for the global Jobs offcanvas.

Without this, URLs that point to /uploads/:id surface in the offcanvas as
their bare numeric ID (the URL path basename) under a generic "Download"
header -- useless for telling apart "Carton Label SSCC123" from
"Pick Slip Pdf for SO718463". When the URL matches a known Upload, we
substitute the Upload's attachment_name (real filename) and humanized
category (worker label) so the offcanvas card carries real context.

Falls back to URL basename + "Download" for non-upload URLs (zip exports,
tempfile results, etc.) so callers don't have to special-case anything.

Mixed into:

  • Controllers::WarehouseStreamActions (Turbo-Stream interception path)
  • FileDownloadsHelper (HTML render path)
