RAILS SHIPS REVERSIBLE FOREIGN KEY MIGRATIONS, PRODUCT REVIEWS TUTORIAL GOES LIVE

The framework just made database rollbacks safer while shipping a complete e-commerce guide that teaches real-world patterns.

Rails merged a critical fix for migration reversibility [1] that makes `remove_foreign_key(if_exists: true)` properly invertible. This closes a longstanding gap where developers could drop constraints but couldn't reliably undo it. On the documentation front, the new Product Reviews Tutorial [2] lands in the guides, completing the e-commerce store series with a full-featured implementation: star ratings, image uploads, automatic product rating updates, and admin management tools. The tutorial demonstrates radio buttons for ratings, filtered views by score, and percentage bar graphs. Shopify also shipped a fix for polymorphic belongs_to relationships with sharded primary keys [3], addressing a pain point for teams running distributed databases. The website team updated the main tutorial page [4] to link the new product reviews guide and removed the 'Coming soon' badge.
