Writing a Sidekiq middleware

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

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
