Ruby on Rails

Ruby on Rails (or simply Rails) is an MVC (model view controller)-based framework used for web development and app programming at the server-side of the applications. In the world of web development, web frameworks are based on a specific programming language. For example, AngularJS is a JavaScript-based web framework. This means that all libraries contained in AngularJS are written in Javascript. In the same way, Rails is a framework written in the Ruby language and extends Ruby to solve problems without a programmer having to reinvent anything.

Ruby on Rails developers prefer it for its time-saving qualities when writing code. The efficiency of Ruby on Rails is due to its ready-made code libraries that contain upfront solutions, thereby saving the time needed to perform repetitive tasks such as building forms, menus, and tables. 

In this article, we will explore Rails programming and provide you with relevant resources to help put you on a course toward lucrative career options such as an automation test engineer. Learning Ruby will also equip you for full-stack development.  

Basics Concepts of Ruby on Rails

Glossary of terms 

Whether you’re a seasoned programmer or have never written a line of code, your decision to learn Ruby will open you to new career possibilities. Back when Ruby first started, it was just a single file. Today, however, it has grown into a glossary of terms, some of which include:

  • Git. This is a generic term used in different programming languages. It is a version control system that allows you to save versions of code and see who wrote which lines. 
  • Github/Bitbucket. This is where developers host and store their projects. To understand it better, you can compare it to dropbox or Gdrive, only with unlimited free space. 
  • RubyGems. This is Ruby’s package manager. RubyGems standardizes formats for distributing Ruby, defines a standard directory format, and allows easy installation of gems.  
  • Gems. These are utilities and libraries that make up the code created by the community of programmers. 
  • Bundler. This tracks the gems you have used on your Ruby project so that whenever there is a gem update, your code won’t break, and your projects will continue operating. 
  • Bundler audit. Built on top of bundler, this is a gem trusted and recommended by seasoned programmers such as rubygarage. Bundler audit searches your gems for security vulnerabilities. 

Getting Familiar with Rails

You can learn Ruby on rails programming from several reliable sources. Rails Guides, for instance, has a comprehensive guide that covers the following areas: 

1. Installing Rails 

2. Creating an application using Ruby on Rails language

3. Getting your application connected to a database 

4. Rails philosophy and guiding principles: DRY (Don’t repeat yourself), RESTful, convention over configuration, CRUD, etc.

  • DRY. "Every piece of knowledge must have a single, unambiguous, authoritative representation within a system" by employing the DRY principle, developers don’t have to write the same code repeatedly, and you achieve standardization.  
  • Convention over configuration. This is a paradigm geared toward increasing productivity by adhering to coding conventions and the best way of doing things. 
  • CRUD stands for Create, Read, Update, Delete. It is a function that guides actions on databases. 
  • REST, short for Representational State Transfer, guides actions performed on URLs. 

5. Layout of applications created with Rails 

6. How to get started using Rails immediately?

Thinkful also has a Ruby on Rails tutorial that covers these and other topics, but a critical element that they point out is the need to pick a goal. They recommend applying your skills to something unique but simple. If you have a small but nagging problem that you can solve with your new programming skills, learn Ruby, and apply your skills to solve it. After a lot of practice on small goals, you will be able to handle more significant projects.  

Note that although a beginner can learn Rails and become proficient very quickly, prior knowledge of Ruby language is an added plus as it will shorten your learning curve. While Ruby will equip you for full-stack development, Ruby garage also recommends learning CSS, JavaScript, and HTML to understand the basics of front end development better. While all of this might seem like a lot to learn, it is also a great way to work toward more lucrative salary brackets in Java development, so you’ll never lose by learning these additional programming languages. 

Note, however, that Ruby is sufficient to help you get started coding, and you can map all of the other languages in your career path.

  • An enthusiastic community contributes to the Ruby on Rails framework, making it ideal for beginner programmers 
  • It’s a consistent and well-written code, without extraneous elements that you would find in other languages 
  • The Framework enables easy testing 

Also, Ruby is always evolving as its creators and support community are always working to improve it.  For example, the 2020 planned release of Ruby 3 is expected to be three times faster (Ruby 3x3). Faster speed will enhance user experience in different quarters, including gaming. 

Career Prospects for Ruby on Rails 

Ruby on Rails developers are still in demand 15 years after the framework’s debut, and this is shown by the impressive portfolio of companies that use it. As mentioned above, companies using Rails benefit from the faster speed of delivery and an agile development approach. Some of the top companies that have used Ruby on Rails include GitHub, Airbnb, Zendesk, Shopify, Basecamp, Twitch, and Cookpad. 

A current search on LinkedIn shows that in the United States alone, more than 3,400 new Ruby on Rails jobs were posted in December 2019 alone. Additionally, the impressive salaries that RoR developers take home show that knowledge of Ruby is something that companies are willing to invest in. This represents new career opportunities.
