Module: Pgbus::Web::JobContext

Defined in:
lib/pgbus/web/job_context.rb

Overview

Presents the Current attributes persisted in a job payload (Pgbus::CurrentAttributes::METADATA_KEY) for the dashboard's Context card: { "Current" => { "tenant" => "gid://app/Tenant/42", ... } }.

Pure presentation: ActiveJob argument encodings are unwrapped to display strings (a GlobalID shows its gid, a serialized Symbol/Time its value) — nothing is constantized or located. Callers pass the payload through PayloadFilter first (ApplicationHelper#pgbus_parse_message does), so sensitive values arrive already redacted.

Class Method Details

.display(value) ⇒ Object

String form of a value for the card. Hashes/arrays that are ActiveJob encodings collapse to their payload; anything else renders as JSON (stable across Ruby versions — Hash#inspect changed in 3.4).
