This Week in Rails is out: This week's PRs made: - Better error handling for primary key columns: `add_column` now raises an error when `:null` is set to true for primary keys, since PKs always get a NOT NULL constraint and the option was previously silently ignored. - Faster Active Record relation merging: calling `extending` on an Active Record relation is now twice as fast. And still more. Read about the week's highlights in the newsletter: rubyonrails.org/2026/4/24/this…

Now 95%+ of daily code is AI-generated, with 1,000+ weekly users enabled across the whole company (including sales, marketing, and finance). @brian_scanlan shares how they got there and where they’re going next on the next episode of On Rails with host @robbyrussell: podcast.rubyonrails.org/2462975/episod…

This Week in Rails: A new `rails query` command lands: run read-only ActiveRecord queries from the command line and get structured JSON output with columns, rows, pagination metadata, query time, and generated SQL. Subcommands include `query schema`, `query models`, and `query explain`. Also: static CSS and HTML files now include `charset=utf-8` in Content-Type, new Rails apps get a PWA offline fallback page, and ParameterFilter gains O(1) hash lookup for exact-match regexp filters.

Hey @rails devs! Before the @PlanetArgon team opens submissions on the Rails Developer Survey (our 9th since 2009!), we want to make sure we're asking the right questions. Not just where we've been, but where we're going. What's the one question you think we should be asking but probably aren't? 👇

Had a great time recording this On Rails podcast episode with @robbyrussell. Wild to think @dnsimple is 15+ years old and I've been building with #Ruby and #Rails for nearly 20y. Time flies when you're having fun!

They chat about what it takes to keep a long-lived codebase healthy with a lean team of around 15 engineers. 🎙️ Listen to the full episode here: podcast.rubyonrails.org/2462975/episod…

This Week in Rails: Action Text's Markdown pipeline gets a security fix this week: URI scheme validation added to `markdown_link` so schemes like `data:text/html` are now blocked and rendered as escaped text instead of live links or images. Plus: async query instrumentation bug fixed, faster generated Dockerfiles, and a SQLite virtual table schema fix. Read about this week's highlights in the newsletter: rubyonrails.org/2026/3/13/this…
