Views in Rails don't do much besides showcasing what we want. Sure, they might render slightly different results depending on who's watching (an admin or a logged-in user has a different experience than a guest user, for example), but they don't do much processing on what they're given. Or at least they shouldn't. Often though, Rails projects wind up with a lot of logic in their views. In this post, we'll explore how to use Rails helpers to keep our views clean and readable.

In this article, Julie Kent discusses using associations in Rails when the underlying data model spans multiple databases. We didn't even know Rails could do this!

ActionCable allows developers to move away from the typical request/response paradigm of old to one where persistent WebSocket connections are maintained from clients to your Rails servers. Event-driven and low-latency, WebSockets are an excellent choice for use cases like live chat, alerts & notifications, and realtime data broadcast.

Business Intelligence transforms raw data into actionable insights that support business decisions through reports, dashboards, and charts. You can use the blazer gem in Ruby on Rails to gather and display business metrics!

As web developers, we tend to approach problems with traditional low-risk solutions. When all you have is a hammer, everything looks like a nail. When you need complex input from the user, you use a form and JSON representation (even if, in retrospect, it is not the most efficient solution). In this post, we'll take a different approach. We'll leverage some tooling to create a business language that extends the functionality of a Rails application. Let's get started!

Rails' date and time helpers are great. They save us from duplicating simple add-duration-to-time logic across our applications and make the code more readable. However, complex date manipulations are dangerous places full of edge-cases. This article discusses some of them. 😅

Ruby on Rails is one of the most popular Ruby frameworks, but it's not the only one. Hanami 2.0 is faster than Rails and packed with exciting features—it might be the tool you need for your next project!

Web applications usually rely heavily on databases, for the most part. And as applications grow, databases grow too. We keep scaling web servers and background workers to keep up with the heavy load. But eventually, the database needs to keep up with all the new connections from these processes. One way to tackle this is to grow a database with an app using vertical scaling. This means adding more CPU power and memory to the database server. But this is usually slow.

Migration in Rails is a tool that allows the developer to use Ruby to change an application's database schema. Instead of using SQL scripts, we use Ruby code, which is database independent, so it is easy to move the application to a completely new platform. We define these database changes in domain-specific language (DSL), and these migrations can be rolled back and managed along with the application source code.
