Class Method Details

.warn(key, message) ⇒ Object

The single internal warning funnel. Speaks to the developer at the keyboard through Kernel#warn (stderr) — never through Rails.logger, which may not exist, may be unconfigured at mounting time, and hides test-run warnings in a log file nobody reads. Deduplicates once-per-key-per-process and is deliberately not configurable: a "where do warnings go" knob would be the first global setting of a gem that has none.
