Lots of good stuff in here, including much more support for using UUIDs as PKs. My favorite new feature is "delegated type" in ActiveRecord to offer a new way to map class hierarchies onto database tables. I wrote a blog post about it[0], but the actual PR is very readable as well[1]. [0] https://www.stevenbuccini.com/how-to-use-delegate-types-in-r... [1] https://github.com/rails/rails/pull/39341

Seems really nice. It's just a Rails abstraction for Multi-table inheritance (MTI) but to me that was sorely needed. MTI always felt much more manageable to me than Single-table inheritance but the latter was the only one with built-in support in Rails, until now.

I did a bunch of work in rails prior to the 3.0 days ( probably around 2013 or so), but then switched domains to work more in data engineering.

When I came back to it to scratch an itch for some pet projects, I barely recognized it. I felt completely lost.

Life moved pretty fast, I guess. Are there any good resources out there for someone from the 2.x days to get back to speed?

Man I'm hoping NEW MAGIC is like Phoenix LiveView. As a Rails dev I started looking into the Elixir/Phoenix world just for LiveView but I don't really want to switch languages... I just want that new magic that LiveView offers. I know there are gems for Rails but I'd prefer if it was baked-in and officially supported.

I fall in this same bucket. I still refer to the old railscasts now and then. I use rails for my hobby projects.

Currently, I depend on Rails Guides, and I think they do a pretty good job. Would be good to know other resources.

Oh shit, I didn't realize that that's the scheduled Christmas release. Finally, all strings frozen by default!

Depending on your patience you can go and take a look at a real life implementation of it at https://app.hey.com since they enable source maps.

What the actual developer facing API is going to look like however is another question. I do kind of worry that given how much is has been talked up by DHH in particular that it is going to struggle to live up to the hype.

Either way, I am excited to see something new in the Rails front end space, that has felt like it was lacking a LOT of structure.

Does a "delegated type" work with preloading associations, ala "includes"? This remains a pain point with many polymorphic associations in Rails, but not sure how the new functionality handles if, if it does at all.

Based on this GitHub comment[0], it appears the answer is yes although it requires a little additional customization out of the box to prevent N+1 queries..

I was sold on hey.com's UI design already because it's using for dropdown menus.

The really fun part, though: the summary content isn't just a menu icon, it's a trigger for some (currently unpublished) Turbolinks variant. The menu content is loaded (and subsequently 304'd) dynamically as a server-rendered partial (sans layout).

Most tellingly, if you visit the menu content's XHR URL with regular browsing then hey.com renders that menu as the sole content in a page layout.

We can't see the server-side parts yet, but if that becomes an out-of-the-box end-to-end behaviour within Rails, then in conjunction with Stimulus 2 and Action Cable I'm stoked about the possibilities. Especially so since I have a mission to replace all my dropdown & modal boilerplate with and elements, and I like to build services that still work if JS is disabled. But it's also good for mundane stuff like progressive form validation in line-of-business apps.

DHH has been teasing something called "New Magic" on Twitter but beyond that we don't know much.
