Tests are an integral part of most well-working Rails applications where maintenance isn’t a nightmare and new features are consistently added, or existing ones are improved. Unfortunately, for many applications, a production environment is where they are put under heavy workload or significant traffic for the first time. This is understandable as such tests are costly.
Today we will install Ruby on Rails (RoR) on a Debian Linux operating system (Ubuntu 18.04 LTS). With that said, RoR is compatible with other operating systems with just a few tweaks. This blog will assist you in installing RoR with a simple step-by-step process. Your installation may differ, for other operating systems refer to this site. I am new to developing and have been using Ubuntu 18.04 LTS, a flavor of Debian Linux, for my projects.
Modules and mixins are, without doubt, great resources that make Ruby so attractive. They give the application the ability to share the code that can be used with ease in other places. It also helps us organize our code by grouping functionalities and concerns, which improves the readability and maintainability of our code. In this article, we will go through the concepts behind modules and mixins.
We’ve been doing some Ruby on Rails development lately, in preparation for PagerTree 4, and we wanted to put together a Ruby on Rails Cheat sheet. This is a quick reference guide to common ruby on rails commands and usage.
Every Rails app has a breaking point; a level of activity that it simply cannot handle. Your braking point depends on big architectural decisions, yes — and also on the tiniest changes committed by your most junior developer. That's why it's vital to regularly test your application's performance under load. In this article, Milap Neupane gives us a Rails-centric introduction to load testing with a powerful open-source tool called JMeter.
Monitoring your application can be a difficult task if you’re just getting started with it. You need to know which metrics matter most and understand which ones you can combine into meaningful graphs. In the (not just holiday ⛄️) spirit of making things smoother for our users, we’ve added a magic dashboard to the Ruby integration that shows you the volume of emails you are sending with ActionMailer.
As we’re doing our best to make monitoring easy, we’ve wanted to make more content that would really show and not just tell you how easy it is to set up monitoring with AppSignal. We’ve been collaborating with Leigh Hallday on making this video for you that will show you everything you need to know about the setup process. We’ll be posting more videos like this on our YouTube channel, so you should subscribe to it if you’d like to get notifications about future videos.
According to a definition of multitenancy, when an app serves multiple tenants, it means that there are a few groups of users who share common access to the software instance. An excellent example of an app that supports multitenancy is the Jira platform, where each company has its subdomain to access the software, for example, mycompany.atlassian.net.
The last 3,650 days of my professional life have been focused on making Rails apps faster. Below are five lessons I've learned the hard way.
If you’ve ever used Ruby on Rails, you’ve probably come across the concept of concerns. Whenever you jumpstart a new Rails project, you get a directory app/controllers/concerns and app/models/concerns. But what are concerns? And why do people from the Rails community sometimes talk badly about them?
