Service Objects are a controversial idea for several different reasons: some developers like to use them, others like to use similar patterns, and some think that they are just unnecessary because they prefer fat models.

Here at OmbuLabs we like to use service objects whenever we can, we think it’s a great way to keep our controllers skinny.

In this post I would like to discuss my idea about service objects and why it’s adopted by our team.

In this blog post I will introduce bundler-leak – A bundler plugin to find known memory leaks in your dependencies.

Every time we start a new Rails upgrade project, we need to setup a whole new environment in our local machines. Sometimes that leads us down the rabbit hole which ends up breaking our environment for other client projects.

After years upgrading Rails applications, we learned that the best way to isolate our client projects’ environments is using Docker.

That’s why we decided to use Docker and docker-compose for all of our client projects. This year I had the opportunity to share our process in a series of workshops: Upgrade Rails 101: The Roadmap to Smooth Upgrades

Here we continue with the series of articles where we talk about how minor adjustments in the code can lead to major performance improvements.

In this article we’ll focus on the use of ActiveRecord::Batches#find_each when it comes to iterations across a large number of records.

This year’s RailsConf was a special conference for me. It was my third time attending and my first time speaking at the conference. I conducted a 2-hour workshop for anyone interested in upgrading their Rails application: Upgrade Rails 101: The Roadmap to Smooth Upgrades

Here are a few lessons learned from running such an ambitious workshop.

Over the years we have seen a significant increase in the demand for Ruby on Rails upgrades. That’s why a few years ago we decided to launch FastRuby.io, our Ruby on Rails upgrade service.

When we receive an inquiry via FastRuby.io, the first thing we like to do is schedule a call with the potential client to get more details about their app.

This article will cover the most important aspects that you need to know to get your Ruby on Rails application from version 5.2 to 6.0.

Next week the Rails community is having the biggest event of the year, the Rails Conf 2019. We participated in previous editions of this conference but this time we have the honor to be on the speakers side of it. We’ll be teaching you what we’re best at: Rails Upgrades.

In this article I will explain how you can dual boot your application in your local environment and your continuous integration (CI) service. I hope that this will help you get ready for the next stable release of Rails.

I had to come up with a clever title because this article is about legacy Rails applications and I know that you might fall asleep by the third paragraph. Boooooring… You probably want to read about that new JavaScript framework that came out (I love that this sentence will always be true, it doesn’t matter when you read this)

If you have been working with Rails for a few years, you have seen your fair share of shiny new applications, well-maintained and poorly-maintained legacy applications. This post is about Legacy Rails applications

At OmbuLabs, we are big fans of Ruby on Rails and design patterns, especially convention over configuration! The beauty of Rails is that you can inherit a legacy project and easily find the different layers of code in different directories.

When it comes to database migrations the policy of Rails is very clear. It’s all about altering the database structure with gradual migration files: “Migrations are a convenient way to alter your database schema over time in a consistent and easy way.” (source)

But, what about data migrations? What’s the best way to write, maintain, and run migrations that alter the data in your production database?

In this article I will talk about three different patterns for writing and maintaining your data migrations:

1. Data migrations in db/migrate
2. Data migrations with a set of Rake tasks
3. Data migrations with data_migrate

If you are interested in Ruby and Rails performance, you have definitely read articles by Nate Berkopec from Speedshop. At Ombu Labs we are big fans of his work, his Complete Guide to Rails Performance book and Slack community.

When Nate announced a series of public workshops I didn’t hesitate and signed up as quickly as possible. Here are my notes from my experience at the workshop on October 17th.

Some time ago we wrote a couple of Tips for Writing Fast Rails. It was about time we wrote part two so here it is!

We recently spoke with Ryan Findley, Principal at Neomind Labs. We worked with his team to execute a Rails upgrade from 2.3 to 4.2 on one of their applications.
