ViewComponents reduce bloat, simplify data, and create reusable frontend styling. Despite these benefits, they're often under-utilized in the Rails community. I've written a blog post refactoring a real-world example into isolated ViewComponents. joshfrankel.me/blog/viewcom... #ruby #rubyonrails

ViewComponents, the Missing View Layer for Rails

If you’ve worked with Rails for any measure of time, then you know that Rails’ Views can quickly get out of hand. Between Helpers, instance variables, and inline logic, they quickly become bloated and...

How do you manage error classes in your app? - Granular — Domain::Specific::NotFoundError - Generic/Reusable — Error::NotFound - Not — StandardError/raise 'x' Personally, I create my own error classes so I can see what's wrong at a glance, even if it means catching existing ones. #RubyLang

Already several good RSS feeds in the thread. Keep them coming! Discoverability is hard these days and RSS was one of those lovely tools that deserves a comeback.

If you've got a blog where you (at least sometimes) write Ruby-related posts, please reply with a link to your RSS feed below. I am going to try to start keeping an eye on those as well and sharing interesting stuff I find from time to time.

Don't want to expose a class' initializer in Ruby? Making it private is easy! Just use `private_class_method :new`. This conveys intent that your class is not designed to be initialized from outside — perfect when you want to use the factory pattern.

Screenshot of Ruby code: class Pizza def self.margherita new(sauce: 'tomato', cheese: 'mozzarella', toppings: %w[basil]) end def self.vegetariana new(sauce: 'tomato', cheese: 'mozzarella', toppings: %w[aubergine mushrooms peppers onions olives]) end private_class_method :new def initialize(sauce:, cheese:, toppings:) @sauce = sauce @cheese = cheese @toppings = toppings end end Screenshot of Ruby code: Pizza.margherita # => #<Pizza:0x0000000121c17f10 # @cheese="mozzarella", # @sauce="tomato", # @toppings=["basil"]> Pizza.vegetariana # => <Pizza:0x0000000120f34988 # @cheese="mozzarella", # @sauce="tomato", # @toppings=["aubergine", "mushrooms", "peppers", "onions", "olives"]> Pizza.new(sauce: 'white', cheese: 'none', toppings: %w[pineapple]) # => private method 'new' called for class Pizza (NoMethodError)

How to automatically trigger a file download with Turbo? The user triggers the creation of a file. That file is created using a background job. I could update the view using Turbo Streams (e.g. render a 'Download Now' button). But I'd like download to automatically start 🤔 #rubyonrails

Incredibly common Rails perf anti-pattern: Rails.cache.fetch([complicated,cache,key], expires_in: random_interval) do dog_of_a_SQL_query end Cache hitrate: 10% (if anyone even knows what it is)

What's the best host for running a Ruby application, that stores files on the server, and runs sqlite as the database, on the server?

Having setters that appear to be at the instance level apply at the class level is something that (for me) definitely would be against the Principle of Least Surprise. An easy way to define class level accessors is nice but hard to see the use case for the instance level behavior.

Consider using pattern matching in Ruby. I wanted to update a user's location (RGeo Point) from an endpoint which receives a JSON object: { lat: ..., lng: ... }. Using pattern matching, we can detect such an object's shape, falling back to a catch-all (_) with an if statement for regular Points.

A screenshot of ruby code. The contents are: class User < ApplicationRecord def location=(value) case value in { lng:, lat: } super(self.class.point_factory.point(lng, lat)) in _ if value.respond_to?(:latitude) && value.respond_to?(:longitude) super else raise ArgumentError, 'Invalid location format' end end end user = User.last user.update!(location: { lng: 4.8922, lat: 52.3731 }) user.location # => #<RGeo::Geographic::SphericalPointImpl:0x4610 "POINT (4.8922 52.3731)">

What's the "Rails" way of designing a multi-step workflow with background jobs? Each job triggering the next, active record callbacks, state machines or something else? Help!

TinyBits is getting a new interesting feature, you can now (using the repo's head) supply the pack/unpack method with an external dictionary. For shorter messages with no duplicate strings this can lead to a dramatic size reduction, from 96 to 34 bytes in the example below
