If you're finding performance bottlenecks with full-text search in your database, it may be time to switch to Elasticsearch. In this tutorial, Ianis introduces Elasticsearch and shows us how to implement an efficient search feature in Rails.
Containers are popular because they create a reproducible environment that you can deploy to production and run locally in development. However, containerizing a Rails app can be tricky—Jeff Morhous helps us navigate the pitfalls.
Picture this scenario: you are a Rails developer and have spent the last couple of days developing that awesome feature that everyone is waiting for. It's big and complex, but it went through rigorous testing, so you are confident everything works as it should. There are deadlines to meet, so you deploy. Immediately, all hell breaks loose. Your feature straight up breaks the entire app for some of your users. It's hard to say why. No bugs showed up during testing.
PostgreSQL and MySQL are great for structuring data using relationships, but what if you don't always know the structure up-front? That's where `ActiveRecord::Store` really shines. It's like NoSQL, without changing databases.
If you have ever spent time building an Object-Oriented Program (OOP), you have likely used polymorphism in your application or, at the very least, heard the term. It’s the kind of word you’d expect to see in a science or computer science textbook. You may have spent time researching polymorphism and even implemented it in your application without clearly understanding the concept. This article will give you a greater understanding of polymorphism, specifically in Ruby on Rails.

Rails' batteries-included approach is one of its greatest assets. No other framework makes it so effortless to get your application off the ground quickly, at least partially due to Rails' generators. If you've used Rails for any amount of time, you have come across generators. Need to create a new application? Run rails new. Need to scaffold a bunch of new models and views? Run rails generate scaffold. There are dozens more available to help you get started rapidly or streamline your workflow.
