✍🏾 Articles

What’s new 🆕

Jean Boussier published an article about Performance Impact Of The Memoization Idiom On Modern Ruby → “One major internal change in Ruby 3.2 was the introduction of object shapes. In this post, we’ll try to cover why they were introduced, how they work, and what their limitations are” and he also published an article about Effects Of Pitchfork Reforking On Shopify’s Monolith

Jorge Manrubia published an article about Exploring Server Side Diffing In Turbo → “We did a lot of exploratory work before coming up with the Turbo improvement we presented in Rails World. One of those experiments included diffing in the server instead of in the client”

Akshay Khot published an article about Akshay’s Blog Is Now Write Software, Well → “After two years and hundreds of thousands of readers, the blog has outgrown my personal domain and needs a new home. Welcome to «Write Software, Well»”

Patrick Helm published an article about My Love Letter To Rails (And Ruby) → “Here's why Ruby on Rails is far from being dead... Honeypot developers are even writing love letters to Rails”

Greg Molnar published an article about Rails Authentication For Compliance → “Suppose you are working on a Rails application that needs to meet specific security compliance requirements like PCI, ISO 27001, or SOC2. In that case, one of the objectives is to have proper authentication and access control”

Alkesh Ghorpade published an article about Rails 7.1 Raises An Error On Generating Model Attributes With Dangerous Name → “Rails 7.1 raises error on generating model attributes with dangerous name. The feature will raise an error if you specify any dangerous attribute when generating a migration” and another article about Rails 7.1 Adds Validation To Enums

Apoorv Tiwari published an article about Limiting Maximum Index Name Length In Ruby On Rails 7.1 → “With the introduction of Rails 7.1, a new 62 byte limit has been specified. If the index name exceeds this limit, it will fallback to a short format, along with a hash that ensures uniqueness”

Vladimir Dementyev published an article about The Future Of Full Stack Rails Ii: Turbo View Transitions → “In the previous post, we introduced the Turbo Music Drive application and enhanced it with DOM morphing techniques to provide a smoother UX. Now, we’ll take it to the next level and add slick animations”

Brad Gessler published a new article about Rails Background Jobs with Fly Machines → “Fly Machines can boot a VM in 500ms, run a Rails background job, then turn off when it’s done. That means you don’t have to pay for a server to sit idle if there’s no jobs to process and you can have a much more scalable pool of on-demand workers when your application starts to get busy”

Deep Dives 🔍

Victor Shepelev published an article about “Useless Ruby Sugar”: Pattern Matching (Pt. 2) → “With all the good things that I’ve said in the previous article about chosen pattern syntax looking natural, it still stands as a separate syntactic area of the code. This is mostly unusual for Ruby, which, once you get to know it closer, is characterized by a uniformity of semantics”

Noel Rappin published an article about Better Know A Ruby Thing #2: Constants – Noel Rappin Writes Here → “Today: constants. They aren’t actually constant. They aren’t only used for small strings or magic literals. They aren’t even mostly used for that in most Ruby programs. Constants are one of the core pieces of Ruby and they aren’t super-well documented in the official site”

Paweł Strzałkowski published an article about Tetris On Rails → “The story behind Tetris on Rails”

How-Tos 📝

Harrison Broadbent published an article about Action Mailer Attachments In Ruby On Rails → “ActionMailer makes it easy to attach files to your emails. In this article, I show you how to attach single or multiple files, set custom encodings and mime_types, and attach images as inline attachments to display in your email body” and an article about Action Mailer Cc And Bcc Multiple Recipients

Sam Ruby published an article about Accommodating Safari Users  → “When you generate a new Rails app, you are given a choice whether or not you want JavaScript support or to include a CSS framework. The default is to use import maps. What isn’t clear at this time is that there is no documented upgrade path should you change your mind later. In fact, upgrading is difficult as support for things like Turbo, Stimulus, Action Cable and Action Text further lock you into this choice”

Stefan Wienert published an article about Rails 7.1 Migrate from secrets.yml to credentials.enc.yml → “If you have been using the Rails.application.secrets feature, you have been able to ignore the deprecation until Rails 7.1. But now, Secrets is gone! We had been using config/secrets.yml in the past because our deployment script would just replace the file during deployment”

Jeffery Morhous published an article about Factory Bot For Rails Testing → “Dive into FactoryBot to ensure your testing data is reliable and consistent”

Akshay Khot published an article about Base64 Encoding, Explained → “This article covers the basics of Base64 encoding, including what it is, how it works and why it's important. It also shows how to encode and decode Base64 data in various programming languages”

Gelsey Torres published an article about How Action Dispatch/Response#Content Type Changed Between Rails 5.2 To 6.1 → “What happened with ActionDispatch::Response#content_type between Rails 5.2 to 6.1? In this article, we will go into some background to learn what this method does, look at the differences in ActionDispatch::Response#content_type’s return value between the several Rails versions, and how you can fix the problem if you come across it in your codebase”

I published an article about How To Skip All Callbacks For All Models In Rails → “Different approaches for avoiding all callbacks on a Rails Active Record model”

James Garcia published a new article about Binged Watched (almost) a Rails Upgrade → “I watched Chad Pytel and other developers from thoughtbot Upgrading a Rails 3.2 app to Rails 7. Be warned it 17 hours over several videos, but it was well worth the time invested. 🙂 I wanted to share some things that I learned”
