I’m upgrading a #Rails app from 7.1 to 8.02. The App uses tailwindcss-rails even though I don’t use any #TailwindCss in the app. I had problems taking Tailwind to 4.x so I pinned it to ~> 3.3.1 per the README. I’d love to get over the hump and get it all the way to 4.x. but there was an @forms plugin that seemed to be missing.

Anyone know of specific steps to upgrade a Rails App? (The instructions seem more geared to a generic App and I can’t seem to make the translation). Boosts appreciated.

Reminder that I’m available to hire for casual #Ruby #Rails #DeveloperExperience things like improving tests, dependency upgrades, and, my favourite, writing code style rules!

It sounds fairly niche, but hey, I know what I like and what I’m best at!

I've seen a lot of content about using #DDD (Domain-Driven Design) with #Ruby on #Rails, but none of it has addressed how to do the "one database per bounded context" pattern--especially in the world of Solid* and SQLite by default.

Does anybody have any strategies for this?

#Rails question: does anyone know if you can enable/disable (and even install?) Rails Engines at runtime, to behave as some sort of dynamic application extension plugin system? I'm wondering about having a way to enable optional features for @manyfold...

Welp, #Ruby just can't quit #Rails. Or the corporate sponsorship dollars which are totally "ick" you might say.

The problem with niche markets—like Ruby—is if you don't stand on moral principles and core values, uh, what is the actual point? I can just pivot to TypeScript and be in the programming mainstream, messy and regularly unethical as it is.

Ruby as a community has lost all appeal. MINASWAN is nostalgia, not present reality. You can have your DHH and your AI!

I'll have no part of it.

Also, important PSA if you're working with #Rails, (and this may actually be a #Ruby thing, or maybe a #PostgreSQL thing, or combination):

I was trying to run a seeds.rb file to load data into my test env db. That script references an external (local) file with a bunch of items, each line being correctly formed data for an ltree path.

I kept getting errors on line one. I tried a bunch of things, and none worked.

Turns out my text file had a UTF-8 BOM, and script no likey.

3+h of madness.

New blog post: how we made more efficient use of a web app's database for a substantial performance boost https://blog.pablobm.com/2025/05/28/batch-and-delay-db-writes-improve-performance/

In short:
1. Group together sequential `INSERT` statements to the same table.
2. Temporarily store large blobs of data in #Redis or similar, if storing in a relational database is only useful later and only in certain events.

There, that's the meat of the article. I saved you having to read it

The specific stack was #Ruby #Rails #Postgres, but the technique was mostly technology-independent.

(And because we have now come to this: no "AI" was used at any point in the writing of this article ).
