Maybe a nav link should look different when it’s the current page, or a form field needs error styling. Since Rails 6.1, the class\_names helper does this cleanly. Instead of… …interpolating conditional classes with ternaries or post-statement conditionals: \
"criterions" "matrix" . pluralize #=\> "matrices" # this one Rails knows! Use… … inflect.irregular to teach Rails the correct pair: #… ## [Handle Uncountable Words in Rails Inflections](https://andycroll.com/ruby/handle-uncountable-words-in-rails-inflections/) _2026-03-23 · Andy Croll_ Some English words don’t have a separate plural form. “Staff” is staff, “metadata” is metadata, “feedback” is feedback. Rails doesn’t always know this—it will happily generate a staffs table or a metadatas route if you let it. Instead of… …fighting Rails when it pluralises words that shouldn’t change: "staff" . pluralize #=\> "staffs" "metadata" . pluralize #=\> "metadatas" "feedback" . pluralize… ## [Declare Acronyms in Rails Inflections](https://andycroll.com/ruby/declare-acronyms-in-rails-inflections/) _2026-03-16 · Andy Croll_ A lot of Rails’s naming magic comes from its clever use of inflections. user.rb defines the User class, backed by the users table, managed by UsersController , accessible at the /users/ routes. Every Rails app generates config/initializers/inflections.rb to let you customise this behaviour. Most developers leave it empty. Then one day you namespace a controller under API and Rails starts… ## [Group Repeated Options with with\_options](https://andycroll.com/ruby/with-options-group-shared-config/) _2026-03-09 · Andy Croll_ When multiple validations share the same if: condition, or multiple callbacks share the same only: constraint, you end up repeating yourself. with\_options groups them together. Instead of… …repeating conditions across multiple validations: class Article \< ApplicationRecord validates :title , presence: true , if: :published? validates :body , length: { minimum: 100 }, if: :published? validates… ## [Customize Model URLs with to\_param](https://andycroll.com/ruby/to-param-seo-friendly-urls/) _2026-03-02 · Andy Croll_ Rails models default to using their ID in URLs: /articles/42 . The to\_param method lets you customize this—use a slug, hide the ID, or combine both for readable URLs. Exposing IDs isn’t dangerous if you scope access properly, but you might want cleaner paths. Instead of… …exposing IDs in your URLs: redirect\_to article\_path ( @article ) # =\> "/articles/42" Use… …the to\_param method to return a slug… ## [Use StringInquirer for Readable Predicate Methods](https://andycroll.com/ruby/use-stringinquirer-for-readable-predicate-methods/) _2026-02-10 · Andy Croll_ You’ve probably seen Rails.env.production? in your codebase to ensure that certain code only runs in production. Instead of having to compare strings, Rails.env == "production" , Rails wraps the string in an ActiveSupport::StringInquirer so you get readable methods like .production? and .development? . Active Support also adds an inquiry method to String so you can use this same pattern in your… ## [Dissecting Series A Rounds (Sponsored)](https://crawlproof.com/a/YWn88BBKa8vj) _2026-02-10 · **Sponsored**_ Two real Series A cases: timelines, investor sequencing, and common founder mistakes. ## [Prefer in? Over include? for Readable Conditions](https://andycroll.com/ruby/prefer-in-over-include-for-readable-conditions/) _2026-02-02 · Andy Croll_ When checking if a value exists within a collection, Ruby’s include? method does the job, but Rails provides a more natural alternative through Active Support’s in? method . Instead of… …reading your conditions backwards with include? : nsync = \[ "Justin" , "JC" , "Chris" , "Joey" , "Lance" \] if nsync . include? ( candidate ) puts " #{ candidate } is in the band" end # Or inline if \[ "Justin" ,… ## [Simple Tailwind CSS 4 Setup for Jekyll](https://andycroll.com/ruby/simple-tailwind-css-4-setup-for-jekyll/) _2026-01-27 · Andy Croll_ Tailwind CSS 4 changed how configuration works.

One small but useful addition is Array#rfind , which finds the last element in an array that matches a condition. Instead of… …reversing the array or using reverse\_each to find from the end: numbers = \[ 2 , 2 , 3 , 4 , 6 , 7 , 8 \] numbers . reverse . find ( & :odd? ) #=\> 7 # or numbers . reverse\_each . find ( & :even? ) #=\> 8 Use…… ## [Year in Review 2025](https://andycroll.com/other/year-in-review-2025/) _2026-01-01 · Andy Croll_ House moves, robot armies, and scratching itches.

I don’t have… ## [Skip Validations in Specific Contexts with except\_on](https://andycroll.com/ruby/except_on-conditional-validations/) _2025-09-07 · Andy Croll_ Rails 8.0 added except\_on as an option to validations . It’s the inverse of on: and lets you skip validations in specific contexts. Instead of… …skipping all validations in your controller: class Admin::UsersController \< ApplicationController def create @user = User . new ( user\_params ) if @user . save ( validate: false ) # Skips ALL validations! redirect\_to admin\_users\_path else render :new end… ## [Rails World 2025](https://andycroll.com/ruby/rails-world-2025/) _2025-09-07 · Andy Croll_ Off I went to Amsterdam via—so incredibly civilized—Eurostar from St Pancras wearing my favourite Made the Scene t-shirt. Had a day mostly to myself in Amsterdam on Wednesday, drinking coffee, eating chocolates , meeting friends, visiting the Anne Frank House and generally enjoying the vibe of the city while avoiding its insalubrious corners. I even mananged a run around the city before the…
