Module: Errsight::Integrations::ActiveRecord

Defined in:
lib/errsight/integrations/active_record.rb

Overview

Subscribes to sql.active_record and pushes each non-cached, non-schema query into the current scope’s DB breadcrumb ring. When an exception is later captured in the same request/job, the event ships with the last 30 queries that ran — turning “ActiveRecord::RecordNotFound” from an opaque stack trace into “we ran these 5 queries before failing on this one.”

This is the killer demo for the Rails wedge. Sentry-ruby has SQL breadcrumbs but they come from a generic Notifications layer that treats every framework the same; here it’s first-class and tuned for what Rails apps actually emit.

Class Method Details

.subscribe! ⇒ Object

Idempotent. The subscriber handle is stored at module level so a double-require (gem reloaded in dev, or required from both the Railtie and a manual ‘require`) doesn’t double-fire crumbs.
