Integrating Trailblazer and ActiveRecord transactions outside of a request lifecycle
When you use Ruby on Rails with ActiveRecord, you can get used to having separate transaction on each request. This is valid also when using Trailblazer (when inside of a request scope), however Trailblazer on its own does not provide such functionality. It means that when you’re using it from the console and/or when you process stuff inside background workers, you no longer have an active transaction wrapping around an operation. Here’s a blog post I wrote on how to add such functionality into your operations.

Improving Large Rails Apps with Service Objects
Nothing has improved my Rails apps more than service objects. A couple of weeks ago, I was asked to help out with an established Rails app. I found a User model that included 28 modules.

Instead of trying to maintain an active fork of it, we’ve decided to maintain a template on top of it, and it works quite well. Check https://github.com/cookieshq/hebillas for more details.
