The Too Early Breakpoint An opinion on why we shouldn't switch to the smallest design too early.

Just read “The Too Early Breakpoint” by @ishadeed.com — and once again, super inspiring to read.
Such a clear way of explaining a subtle responsive design problem, with practical takeaways you can apply immediately.
Always a pleasure to read your posts 👏🙏

Needed a helper to find the next occurrence of a date (birthdays, holidays, etc.), so I built it.
Now it’s an open @rubyonrails.org.web.brid.gy PR: Date.upcoming_date(month, day) 🎉
Proud to give back to the open-source community that gives us so much ❤️
Hope it gets merged 🤞

XPath Playground | DotRuby Test XPath expressions against HTML snippets.

Just launched a little side tool 🚀
Test XPath expressions against HTML snippets right in the browser.
Built with Rails + Nokogiri, CodeMirror, and Catppuccin ✨
Perfect for experimenting with XPath expressions 🧪

Adding File Validation to Lexxy Editor with Stimulus A simple Stimulus controller to validate attachments in the Lexxy editor — restricting file types and sizes before they get uploaded.

Inspired by @donnfelker.bsky.social’s Stimulus controllers for Lexxy, I built one that adds file type and size validation directly in the editor.

Big thanks to @jorgemanru and the @basecamp team 🙌

Rails Without Ruby Yes, you can run Rails without installing Ruby. With VS Code devcontainers, your whole Rails setup lives inside Docker — no version managers, no sy...

You don't actually need Ruby installed to work with Rails locally 🤯
I wrote about this odd idea: “Rails without Ruby”

Easy Redesign in Rails: Run Old and New Side by Side with :variants Rails variants are usually used to serve different views for devices — but you can use them for much more, like running a redesign side by side.

Redesigning a Rails app? 🚀
We discovered an underrated feature: :variants.
With just one magic suffix you can run old & new layouts in parallel — no JS, no cookies, just Rails ✨

Discovered a neat trick in the turbo_power gem by @marcoroth.dev 💡
turbo_stream.toggle_css_class supports force:, just like the DOM API.
No need for manual logic — may the force: be with you 🛸✨

HexaPDF gem from @gettalong.bsky.social made it super easy to add PDF form filling to our rails app 🙌

The hardest part? Finding the PDF form field names 🤯
We wanted to give back, so we built a tool to list them all:
dotruby.com/tools/hexapd...

Drag a PDF → see all field names → done ✅

🚨 Rails tip: Appending query params with concat or + "?..." can break your URLs — especially if the URL already includes parameters.

Instead of risking invalid or double ?s, use a proper helper that merges params safely. 👇

💡 I needed to check if a string is a valid app path in my Rails app — surprisingly, couldn’t find a built-in way.

So I wrote a small helper method.
Sharing in case it helps someone — or if there’s a better way? 🤔👇

I remembered today and thought I'd share:
You can use .many? instead of count > 1 — more readable and sometimes faster!

💡 On relations: uses LIMIT 2
⚠️ On associations: loads all records

Anchor links not scrolling correctly in your Rails app?
Turbo Drive intercepts clicks and replaces page content via fetch (not a full page reload) — and that breaks native #anchor scrolling.
Fix it with data-turbo="false"
Tamed the Turbo — anchor away! ⚓

Just discovered you can add an if after a content_tag block in Rails views — way cleaner than wrapping the whole thing!
Always finding little gems in ERB 💎😍

Pluralizing model names in Rails with proper i18n — there's a helper for that.
I wrote a small helper that uses model_name.human(count: ...) to do it the right way — fully i18n-ready.
Simple, readable, and it works with any model as long as it's been translated 😉

💡 Clean Rails views with conditional wrapping?

Use conditional_tag to wrap content in a tag only if a condition is true.

No more messy if blocks in ERB. Just clean, readable templates.

Discovered this gem thanks to @scarfacedeb 🙌

Nobody likes to pack — not IRL, not on GitHub. 🧳

So I built github-repo-manager:
For when you're leaving a GitHub org and want to take all your repos without the manual drag-n-drop drama.

One script. No cardboard boxes. 🐙💼

I released version 0.4.0 of active_hashcash. Thanks to @ivanverges.bsky.social and @elalemanyo.bsky.social for their contributions.

ActiveHashcash protects Rails applications against bots and brute force attacks without annoying humans.

💡 Turbo Tip: Preserve search state and update the browser's URL when paginating within a <turbo-frame> by adding data-turbo-action="advance".

This promotes frame navigation to a full page visit, enhancing user experience.

Screenshot of the following text: "👉 All about Code and Ruby There a lot of code samples included; here are just some of them: Andy Croll shared his Ruby solution to a Cassidoo coding challenge, using Rails' Active Support for time manipulation to find the longest time gap between a series of times. Prabin Poudel shared a useful Ruby tip about Array.wrap Hans Schnedlitz shared a tip about speeding up Rails migrations by using bulk migrations with the bulk: true option in change_table Ruby Cademy highlighted String#scrub as an underappreciated Ruby method that helps clean up problematic character encodings Victor Cobos shared a useful technique for detecting newly attached files in Rails with Active Storage, using before_save callbacks David Heinemeier Hansson shared a code sample from Basecamp’s diff feature, unchanged since 2016, highlighting Ruby’s readability and longevity."

Here are just some highlights from All About Code and Ruby section from:
@andycroll.bsky.social @coolprobn.bsky.social @hansschnedlitz.com @RubyCademy @elalemanyo.bsky.social @David Heinemeier Hansson

But there are much more code samples to be inspired and write beautiful #Ruby

Ever forget how @github.com-flavored markdown does callouts?
Same 😅

Now I just type :note, :tip, :warning, etc. and espanso.org fills it in for me ✨

Thanks terzi_federico for making this possible 🙌

Found a good way to check if a file was newly attached in Rails
For has_one_attached or has_many_attached

Hope this helps someone save time! 👇

I was getting tired of my logs being flooded with Sass deprecation warnings when compiling bootstrap in my rails app 😩

Turns out, you can silence them by just adding this:

--quiet-deps --silence-deprecation=import,global-builtin

No more noise! 🚀

🚀 Keeping your JavaScript dependencies up to date is easier than ever!

Just discovered a neat @vscode.dev setting:

"debug.allowBreakpointsEverywhere": true

Turns out, you can set breakpoints literally anywhere — *.html.erb, *.turbo_stream.erb, you name it. No more “breakpoints can't be set here” nonsense. Feels like cheating, but it works. 😎

✨ Conditional form fields with pure HTML & Tailwind!

Want to show/hide fields based on selected option? No JS! Just use group-has-* from Tailwind.

#1: Show input when selected.
#2: Show a different <select> for each option.

🔥 Works great for forms with dynamic inputs!
