Class Method Details

.route_template_for(env, payload) ⇒ Object

Extract “<METHOD> <path-template>” from a start_processing payload. Returns nil when no template is available — the middleware then falls through to Beacon::PathNormalizer, which is the documented cross-client fallback and emits the same shape. We deliberately do not emit a controller#action string here: mixing two label shapes on one dashboard produces confusing groupings.

Source of truth: ActionDispatch::Request#route_uri_pattern (Rails 7.1+). This is a method on the request object, not an env key — the matched pattern is stored on the request instance by the router and read via the public accessor.
