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.

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!

[@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! 🤘

[@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

[@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.

[@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!

[@user-gj8fb8bl5g]

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 ;)

[@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

[@abdellahramadan9001]

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

[@Ostinslife1]

Gonna have a fun time teaching this to students.

[@cnphause]

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

[@Deanin]

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

[@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.

[@AndreyAzimov]

Thank you for keep doing this all these years!

[@vinimartinson]

thanks DHH, God bless you for such wonderful fw!

[@jwaiswa]

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

[@ilkveson244]

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

[@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

[@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.

[@edu28811]

Thank you, DHH. God bless you.

[@antoniotrujillo7636]

All what has been achieved for RoR7 looks great. Well done again for helping the community and taking the time to prepare&present this intro to RoR7. Thanks all the team and individuals that have made Ryby & Rails possible.

Hey people, I have a question to anyone who can answer. Suppose I have a model called Post which has two attributes, title and description. The traditional way of NEW & CREATE and EDIT & UPDATE handle one instance at a time. But how can I implement a functionality of saving/updating multiple instances at once using one single submit button. (Preferably with SIMPLE FORM)

[@DanielMoraisdmgm]

I went through the same problem (in stacktrace: Could not open library 'libvips.42.dylib'). This indicates there was some missing libs in my os (mac os) so I've installed vips (brew install vips) and the problem mas solved.

[@frankbuss]

@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?

Does rails come with built-in authentication system or does it rely on people using gems such as Devise?

[@Lucas-bh3et]

devise

[@mikopiko]

@@Lucas-bh3et So Rails rely on the auth gems?

[@JosueAdeLima]

@@mikopiko yes

[@codecruz]

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.
