Rails 5 Features You Haven't Heard About
summary
Most of Rails 5’s value here is concrete: the type attributes API (implemented largely in 4.2) adds an attribute class macro that accepts type objects so coercion works with where and named scopes; ActiveRecord::Relation#or accepts another Relation to encourage composable scopes; a tiny metadata table blocks accidental destructive DB commands; migrations record a Rails-version bracket so old migrations keep old behavior; accessed_fields lets code select only the columns actually used; boolean parsing tightens several ambiguous truthy values; Ransack and PGcrypto illustrate real-world workarounds tried.
