Rails 7: The Demo

[@Akitando]

The 15 minute Blog from 2005 was mighty impressive back then, and to this day there's still not many solutions that can accomplish the same this easily without a lot of tweaking.

After watching this i am thinking about all the things i spent hours on working with react which he did in minutes

[@hongqiwang988]

I used RoR to build a few side projects. About 8 years ago was the last time I worked with Ruby On Rails, and since then I've been focused on backend development at my job. It's amazing that I can still understand this demo without any problem. There are some changes, e.g. how js is imported, and the live updates support. But it's like old friend and everything is so familiar, including the Textmate editor and the theme... Over the years I gave react/nextjs a few tries, it's too complicated for me or I didn't try too hard. I think I will come back to RoR, for my next project. Thank you for evolving the RoR and keeping it simple!

[@MuhammadSohaib-v8s]

js import has been changing with almost every major rails version. its been a pain tbh. import maps however definitely seems like the best system we've had so far! ruby itself has come a long way. and of course rails is friendlier than ever. definitely give it a shot in spare time ;)

[@externix]

Presentation style: DHH from 2010 🙂 The time of Rails and Railscasts. Thanks for the presentation and nostalgia!

[@hass89]

Rails never ceases to amaze.

[@andycyz]

yeah! 🤘

[@MrSama1000]

As a CE student in my final year, the things that I see being developed in RoR and Hotwire just blow my mind. This is very inspiring and by working on projects using this tech stack I have learned and understood a lot.

[@harryuan65]

Just FYI: I was following the steps, and rails crashes after uploaded the image with "Cannot load vips", you need to brew install vips first

[@abdellahramadan9001]

I am going to build my next project on Rails. Thanks for the amazing work.

[@jarredmacquoid7688]

This demo of Rails 7 showcases its powerful features and improvements, making it an exciting update for developers. Can't wait to try it out!

[@dupre7416]

I've been developing software professionally since 1990. I've written code in dozens of languages over the years and Ruby on Rails is by far my favorite.

[@ChadWoolley]

Same, except lack of type safety in Ruby was a big downside. Looking forward to trying some of the Ruby 3 type safety and pattern matching.

[@darkamenosa03]

​@@ChadWoolley I don't think it is a downside. I am too tired of doing Typesafe things from Java/C# ... That's why I switch to scripting languages. Typesafe doesn't ensure the correctness of the program. lol! If they added typesafe to Ruby, many developers would stop using it.

[@SlavaEremenko]

@@darkamenosa03they can always add optional type definitions, the way PHP was updated

[@Ostinslife1]

Gonna have a fun time teaching this to students.

[@AndreyAzimov]

Thank you for keep doing this all these years!

[@potloodgum]

Thanks for this! Teaching Rails today, really fun and happy with the javascript approach, beginning students really get demotivated by all those front-end frameworks.

[@je9625]

Not only is Rails good and getting better, David is also a great teacher. This demo is better than most of the tutorials out there.

[@jwaiswa]

This is beautiful... I make a living off rails, and so glad to see the passion here...

God do I miss developing in RAILS 🥰 Thank you so much for creating it DHH 🥰

[@dream_emulator]

F*CK YES! This is awesome. I haven't been this stoked to build something in like 10 years. Thanks for putting the spark back.

[@Deanin]

Very fancy, glad to see some of these changes evolving from what we had in Rails 6.

[@vinimartinson]

thanks DHH, God bless you for such wonderful fw!

[@LuisFlores1961]

The more I learn Rails, the more I love it, thank you!

[@richdownie3037]

🏆The hot-wired comments bit takes me back to your Canada-On-Rails (Vancouver 2006) demo. I think you called it Armageddon back then 😆 Bravo, thanks David!

[@ChiragThakur09]

WoW, I wonder why you have not published any full courses on ruby on rails, your teaching is so well. I watched the whole video and was able to follow through quite well.

[@darkamenosa03]

Maybe he doesn't have time to do that.

[@MobileGamingMomentsGG]

Do you know who he is? He doesn't have time to do that.

[@terryhenyo9216]

Even if the Rails documentation is great, I wish there are more learning resources when version 7 comes out. I've noticed that books/tutorials/videos on Rails has been declining ever since version 5. It's a shame really, judging by the course enrollments on Udemy and YT video views, people are still willing to learn it.

[@programmingcheatsheet]

It's absolutely impossible to find any reasonably good video tutorial content that covers creating a practical full stack application using stimulus and hotwire. Even this video just sort of waves a hand at turbo frames and any information about turbo streams and just throws in like a line of code to demonstrate that it exists and moves on without any further explanation. It's very frustrating as a developer trying to learn how to use rails for real life things

[@cnphause]

My favorite part of this is watching a guy like DHH also "forget to edit the routes file". We're all the same. 🙂

[@makeitnow_in]

He just shows of how cool and awesome his creation is. Awesome content

[@InLightFilm]

Thank you for hotwire. It literally changed the world. I can't believe what it can do. Thank you for all the great work that you have done .

[@jademermaidmusic]

How did it change the world? There’s not a single major Rails app that uses it (no, Hey is not a major app, they’re an outlier in the email market).

[@Nuatheone]

Hotwire is pretty much useless in many cases, it will become like turbolinks, first thing to uninstall after rails new...

[@ilkveson244]

I've been following the evolution and development of Rails with admiration. I especially liked the refresh made on the javascript side.

6:02 Does rails console now print attributes line by line by default? I always need to bundle add amazing print gem or sth alike to do that.

[@aftakitani]

So Rails is now twice slower to develop since we went from Blog in 15 minutes to blog in 34? Just kidding! Thank you so much for this awesome release!

@Ashvith Shetty No, I found the problem: I missed this in application.js: import LocalTime from "local-time" LocalTime.start() I think I wrote it, but then I changed it from the CDN to the downloaded version, and maybe the importmap tool deleted it?

@@mikopiko yes

You can build your own authentication pretty easy. No need to rely on devise. Just need to understand how authentication works.

[@mikopiko]

@@codecruz I see what you mean, but even if I knew how it worked, I would still prefer to not build my own auth system on a serious project, the stakes are too high. I would continue on relying on the battle-tested third-parties.

¿Are you the real David Heinemeier Hansson RoR's creator?

[@dennis.blondell-decker]

Ruby on Rails is still one of the best complete solutions for a web application. At some point looking through this video, it all becomes magic hieroglyphics, incantations with a particular taste for how to do things, but nevertheless what I would call search-driven development because you have to search the web for how to do things, even if you read a book or two on the framework. I suppose this is normal for any kind of framework that becomes a world unto itself when trying to handle everything, and that's fine when you want a quick turnaround. If you want engineering instead of tooling, look elsewhere, or let yourself be inspired by this! It is instructive to compare this video with the original demo of Ruby on Rails from 2005 in half the time. It truly is amazing how many things Ruby on Rails handles for you without too much fuzz.

Awesome!
