Have you ever wanted to create static pages in Rails? These are pages that don’t necessarily contain any dynamic info or pull from the database and don’t require an entire controller. While some pre-built gems allow this to be done...

When you first decide to begin your coding journey — and maybe even pursue a career in web development — it can be difficult to understand industry terms like front-end, back-end, and full-stack. What are these different web development roles?...

Long weekends are good. They need not be too long to be good. A workday off on a Friday makes a weekend a long weekend. Though it's just a single-day addition to the regular two-day weekend, the quantum of relaxation and creativity it brings is more than 33%. You could go on a long drive to the beach and have fun. Rather than long drives and beaches, a programmer's idea of fun is to design and implement a mini-project outside of their work domain.
During one long weekend this year, occasioned due to the harvest festival Makar Sankranthi falling on Friday, the 14th of January, I ventured to program the task of finding the number of syllables in a word.
Ruby on Rails, also known as RoR or simply Rails, is an open-source structure for web development in Ruby, a thing object-oriented programming (OOP) language like Perl and Python.
Ruby on Rails is the super-useful better approach to foster full-highlighted web applications. With Ruby on Rails, amazing web applications that once required weeks or months to create would now be able to be delivered in a matter of days. For developing amazing web apps, you can hire ruby of rails developers on a contractual basis.
If you are a Ruby on Rails developer, I think you'll really enjoy this article. It aims to help you get started with TiDB, an open-source NewSQL database, and use it to power up your Rails applications.
TiDB is an open-source NewSQL database that supports Hybrid Transactional and Analytical Processing (HTAP) workloads. It is MySQL compatible and features horizontal scalability, strong consistency, and high availability.
If setting up a virtual development environment is your goal, here is a guide on how to utilize the Vagrant box and virtual machine for this purpose. Let’s discuss the process in detail with this blog.
Here, we will build a Vagrant on top of a virtualization engine as VirtualBox.
Millions of business enterprises are competing to set a foothold in the competitive market. As technology trends are changing fast, businesses look at the mobile and web application sectors to reach their audience and serve them. Technological advances and the availability of app development tools and technologies propel organizations to pick the best one as per their changing needs. Broadly speaking, the tech stack is the mechanism that makes your website or web app run smoothly. Hence, technology stacks catch all eyes when it comes to developing a programming project. Moreover, it isn't easy to pick up the right tech stack for newer web projects.
A 2020 survey on the usage of libraries, frameworks, and tools among software developers globally by Statista, a data research company, shows that Node.js is the first choice of 51.4 percent of respondents. .NET, .Net Core, and Pandas are preferred by 35.1 percent, 26.7%, and 15.5% developers respectively. The survey also exhibits the usage growth of newer technologies like data analysis and machine learning.
Every web developer has run into this at some point.
You’re working on a site or an app, and you need to watch the logs, but all you can see are the requests for the static assets — images, stylesheets, fonts, and so on — making it impossible to see the log entries you care about.
Ever open up a Rails console to debug a problem and come away wondering how the data got so funky? Despite our best efforts, the database will accept plenty of garbage data if you let it. There are tons of methods to bypass the Rails callbacks and validations while still updating your database. If you are like me you have probably used these methods in the Rails console to fix some of that funky data you found after some other code created it in the first place.
Active Record Validations are a good place to start to prevent the funk. They will check the attributes for presence, absence, numericality, length, inclusion, format, exclusion, acceptance, and more. You can validate your model’s data easily and prevent any number of common errors this way. They aren’t the end of the problem but for most funky data you see your mind should go to checking the validations and probably writing another one.

Are you thinking about migrating a Ruby on Rails project CI pipeline to Github Actions? You will learn how to configure the Rails app to run RSpec tests using GitHub Actions.
This article covers a few things for Github Actions YAML config:
How to run Ruby on Rails tests in Minitest on Github Actions? What to do if tests are slow? How to manage complex workflows? You can use Github Actions build matrices to divide Minitest files between jobs and run the test suite much faster.
If your Minitest tests are taking dozens of minutes and you would like to save some time for your Ruby engineering team then you could use tests parallelization on your CI server.
How to start CI build faster by loading Ruby gems from cache on Github Actions? You can start running your tests for a Ruby on Rails project quicker if you manage to set up all dependencies in a short amount of time. Caching can be helpful with that. Ruby gems needed for your project can be cached by Github Actions and thanks to that they can be loaded much faster when you run a new CI build.
You will learn how to configure Github Actions using:
Jeremy Evans is the lead developer of the Sequel database library, the Roda web toolkit, the Rodauth authentication framework, and many other Ruby libraries. He is the maintainer of Ruby ports for the OpenBSD operating system, and has contributed to CRuby and JRuby, as well as many popular Ruby libraries. We are happy to present a brand-new interview with Jeremy to our readers. Hope you enjoy it!
Evrone: You became a Ruby committer and received the Ruby prize 2020 with your work on keyword arguments separation. Could you tell us how did it happen, how did you feel about that?
Creating dynamic applications with Rails (or any language + framework combo) has become more of an ongoing process than a single event. Users often require the best experience when using apps, and this often means that a team of developers ought to continue improving their code on a regular basis. Feature flags in Rails are the way to deliver new functionality and, well, features to users without risking the user experience factor.
There are various reasons why using feature flags has become the norm these days, but you should be clear on when and how to implement them to your feature deployment scenario. This article will help you understand the benefits of using feature flags. We’ll also show you an easy way to have them ready and waiting when using Rails. You may as well get acquainted now since they seem to be here to stay.
Our friend Yukihiro Matsumoto, creator of the Ruby programming language, joined us for an interview right after the release of Ruby 3.0! Grigory Petrov, Developer Relations at Evrone, spoke with Mr. Matsumoto about the new features in the latest major Ruby release. Mr. Matsumoto also shared details about his approach to improving Ruby and gave us insight into the future of the language.
Grigory: My name is Grigory Petrov, and I am here to interview Yukihiro Matsumoto, author of the Ruby programming language, just a few months after the major Ruby 3.0 release with all of its new shiny features.
You will learn how to run RSpec tests for your Ruby on Rails project on CircleCI with parallel jobs to shorten the running time of your CI build. Moreover, you will learn how to configure JUnit formatter to generate an XML report for your tests to show failing RSpec test examples nicely in CircleCI web UI. Finally, you will see how to automatically detect slow spec files and divide their test examples between parallel jobs to eliminate the bottleneck job that’s taking too much time to run tests.
Here are the key elements you need:
Heroku is a platform that enables developers to build, run, and operate applications entirely on the cloud with multi-language support for Ruby, Go, Scala, PHP, etc.
Ruby on Rails is a popular web framework written in Ruby. This guide covers how to deploy Rails 6 apps to Heroku.
