Powerful Rails Features You Might Not Know
summary
Covers concrete Rails 7 and 7.1 features and how to use them: use excluding to drop records without raw SQL, enable strict_loading on associations to raise N+1 errors, and embed models via ActionText attachments using SGIDs. Shows generated columns, attr_readonly, with_options, custom Turbo Stream actions (browser notifications), ActionMailbox inbound reply handling, authenticate_by for timing-attack resistance, normalizes for setters, token generation with expiration, and Active Storage named variants with preprocessed background jobs. Examples include code snippets and end-to-end workflows that run in production.
