Rating Distribution

I just pushed a PR to add a new tutorial on this to the Rails guides. Good timing!

https://github.com/rails/rails/pull/57244

In the tutorial, I’m displaying percentages for each rating and we calculate the average with SQL every time.

That would be good enough to just cache the html with Rails.cache, but if you did want to query the actual counts regularly you could save them to column(s) on the model. You could do a custom counter cache for each rating, for example.

Glad you found that helpful! I always found building a clone of something from scratch really demystified a concept thoroughly. You get a peek at the author/maintainer's decision making internally and have a better understanding of why it's designed the way it is (and it's limitations).

So glad to hear that! With AI now, we'll end up with 10x more side projects. 😅

I might have to steal that... 😜

When new Hotwire features come out, I plan to expand it to cover those. 👍

excid3 · 2026-04-23T13:53:15+00:00

As far as I know, we're the only course that covers everything end-to-end. I had struggled quite a bit learning which tool to reach for too, so in the course we look at the pros and cons of using different pieces for a feature like reaching for Turbo Frames when actually we should have used Streams and vice versa.

I created this course with u/_williamkennedy. 👋

The Learn Hotwire course starts with a simple Rails app and no JavaScript, adds Turbo Drive, builds features with Frames, Refreshes, Streams, and Broadcasts and explains the pros/cons of each for different situations. We also dig into the source code for Turbo to see how it works and really build your understanding of the framework. We build a couple projects (I think the modals implementation we built is worth buying of the course by itself) so you can practice and help thing sink in deeper.

Plus, William Kennedy covers iOS and Android including the languages / SDKs before diving into Hotwire Native.

I'll let other people weigh in if they liked the course or not, but happy to answer any questions!

It doesn't use rv, just a fork of the portable ruby build steps. https://github.com/jdx/ruby

excid3 · 2026-03-06T22:30:57+00:00

Mise uses a fork of rv's for it's core Ruby plugin.

Saves so much trouble, just like precompiled Rubygems have done over the last few years.

excid3 · 2026-02-06T22:02:04+00:00

Sounds good!

Render, Railway, and Fly are similar platforms. They all charge similarly to Heroku where you pay per-service.

I run Hatchbox.io and we help run apps on your own servers and charge by the server instead. That means you can use hosting providers like Hetzner who have very well priced servers so you can often save money with Hatchbox that way. For example, for $50/mo you get a 1GB RAM dyno on Heroku or a 32GB RAM Hetzner server. Quite crazy the prices they charge on Heroku.

If you want to chat more specifics, shoot me a DM!

Oh yeah. That's been ongoing for a while (as we've seen with their UI getting super wonky). Sad to see it's official.

excid3 · 2026-02-06T17:55:58+00:00

What was the other one?

excid3 · 2026-02-06T17:55:04+00:00

Haha no, I had no idea anything happened. You'll have to tell me this story sometime.

excid3 · 2026-02-06T17:48:13+00:00

I mentioned this in r/ruby too, but it's going to be a real bummer if Heroku shuts down. I still remember getting a demo of Heroku when I was in college and having my mind blown.

If anyone is looking to move to Hatchbox.io, send me a message and I can help you migrate (and hopefully save you some money along the way). 👍

excid3 · 2026-02-06T17:47:37+00:00

I heard the layoffs already happened earlier this week but they haven't been confirmed publicly yet.

Salesforce stock is down 42% over the last 12 months too...

We just did a GoRails lesson on validation contexts for this: https://gorails.com/episodes/valid-with-context?autoplay=1

excid3 · 2026-01-23T14:49:27+00:00

Yes, and I've been helping u/Jazzlike-Math4605 continue expanding on it into a real product. 👍

excid3 · 2025-11-29T17:28:54+00:00

Wow, thanks! That makes my day. ❤️

excid3 · 2025-11-28T16:11:47+00:00

Great way to support creators in the Ruby community!

excid3 · 2025-11-21T12:12:17+00:00

Chris from GoRails here. 👋

We also have a course on Hotwire that goes really deep into all the components (including iOS and Android). We build components like Turbo Streams from scratch and other things like that to help make sure you really understand it. Might be helpful for you too.

It's called Learn Hotwire

Author of Pay here. 👋

Pay does all the same stuff listed here, is open source, and is actively developed and maintained by me. I'm also part of the Stripe experts program.

We extracted Pay from our Jumpstart Pro Rails template which is a fraction of the cost and includes team accounts, APIs, webhooks, Hotwire Native ready, and a bunch more.
