Rails 5 Features You Haven't Heard About
summary
Rails 5 arrives after almost a thousand commits and adds many small but concrete changes: a new typed attributes API that centralizes type casting and enables encrypted-column workflows, a Relation.or method to union two relations and favor reusable named scopes, ActiveRecord ignoring DATABASE_URL by default while tracking environment in internal metadata to prevent accidental destructive ops, migration files tagged with the Rails version to preserve migration DSL behavior, accessed_fields for finding unused columns, and a flipped boolean-casting blacklist.
