Architect Properly, and Know Your Tools
This post addresses some bad habits. I’ve seen a common thread in old apps, both my own and others’, where data which belongs in one model is duplicated and stored in another model, either for performance or convenience reasons. Knowing a few fundamentals of development, architecture and knowledge of the right tools for each job solves that. [more inside]

Writing a Sidekiq middleware

Introduction to ActiveRecord and ActiveModel Attributes API
Rails 5.0 is without a doubt a great release with plenty of useful changes and additions. The most notable change was probably ActionCable - the layer responsible for integrating your app with websockets. However, there were also other additions that could bring some substantial improvements to your Rails apps, but were a bit outshined by bigger changes. One of such features is Attributes API.

How to Easily Configure and Run Multiple Rails Apps Locally
This post shows how I tackled the issue with running multiple apps that have conflicting services (notably, Sidekiq and Redis). Sometimes while you’re developing Rails apps, especially microservice architectures, you need to be able to run multiple apps on your development machine. Read on to see how I quickly and easily solved that problem using Foreman and a few configuration changes. [more inside]
«80-chars lines» Rails template
If you use linters like rubocop, they usually check for maximum line length. Fresh-baked rails app contains several files with very long lines which trigger linter warnings. This rails template wraps all long lines in the new app at 80 chars.
Find where the method lies : source_location
While checking out some Rails magic happening or even while rollercoasting into a very large codebase, it would be really super duper helpful if there could be something that would help to find where the method was defined. [MORE INSIDE]
flexible_permissions gem is out for flexible Ruby APIs!
For building APIs (and not only) I have been using Pundit gem for years. It’s an awesome gem. However there is a tiny issue: Pundit has a black and white policy whereas in APIs usually you need a grayscale. The user might have access to a specific resource/action, but only in certain attributes of that resource. That’s why flexible_permissions was born: a successful pattern I have been using for a couple years now is wrapped in a gem! Checkout the github page for more info!
How to Detect Things in Images from Ruby with Amazon Rekognition
Yep, Amazon now has an image recognition service - it’s called Rekognition (great name, right?) and I’ve found the official AWS SDK for Ruby already has support and makes it dead simple to detect things in photos from Ruby. Like, in less time than you might take for a toilet break.

A Step-by-Step Guide to Debugging SJR Templates
SJR is a double edged sword in that it’s awesome when it works, but can be a nightmare to debug if it doesn’t. Over time I’ve developed a sort of systematic approach to debugging SJR templates that I use to track down mistakes in the template and stay on SJR’s good side. I shared my technique (along with a cheat sheet PDF) in my latest blog post… http://www.carlosramireziii.com/a-step-by-step-guide-to-debugging-sjr-templates.html
