Create a Business Language for a Rails Application

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!

Database Performance Optimization and Scaling in Rails

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.

What is Migration in Rails?

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.

System Notifications with Noticed and CableReady in Rails

Notifications are a typical cross-cutting concern shared by many web applications. The Noticed gem makes developing notifications fantastically easy by providing a database-backed model and pluggable delivery methods for your Ruby on Rails application. It comes with built-in support for mailers, websockets, and a couple of other delivery methods. We'll also examine the merits of using the CableReady gem for triggering system notifications in your Ruby on Rails application. Let's get into it!

How to Scale Ruby on Rails Applications

Today we will dive into some strategies you can use to scale Ruby on Rails applications to a huge user base. One obvious way of scaling applications is to throw more money at them. And it works amazingly well — add a few more servers, upgrade your database server, and voila, a lot of the performance issues just go poof! But it is often also possible to scale applications without adding more servers. That's what we will discuss today. Let's get going!

How to Handle an ActionController:: RoutingError in Ruby on Rails

The ActionController::RoutingError is the most common error faced when working on a Ruby on Rails project - it’s equivalent to the classic 404 error in web applications. The ActionController::RoutingError indicates that there isn't a route in the application for the URL entered by the user in the browser.

Ruby on Rails: 10 Trending Design Patterns

Developers can develop agile applications using these conventions and write less code. Moreover, Ruby on Rails developers' communities can be enhanced in terms of maintainability and understandability. Furthermore, the developers use the Rails conventions and sensitive defaults in their web applications, making them more scalable. Among them are email management, object-database mappings, file structures, code generation, element naming and organization, etc.
