Do you want to learn programming in your spare time, especially the popular Ruby on Rails programming language? Certainly, you might be looking for the best Ruby on Rails tutorial for ease of learning and finding important insights about it. Well, we know what your struggles are while finding a suitable Ruby on Rails guide along with effective Ruby on Rails hosting solutions, but we have the solution for you.

Ruby on Rails, also known as Rails, is a popular web development framework. It makes it easy by providing ready-made structures and functionalities, thus letting developers learn to write codes, work with fewer codes, and concentrate more on the distinctive features of their web applications.

Rails is praised for its simplicity and adherence to the Model-View-Controller (MVC) pattern. This separates application logic, data presentation, and user interaction into distinct parts, which leads to more organized code that can be easily maintained. Therefore, people looking to build web applications effectively will find Rails one of the best choices given its large community and many available resources.

This detailed insight is your ultimate destination if you want to start using Ruby on Rails helping you get efficient web hosting plans to launch your projects. We’ll take you through a beginner-friendly tutorial on Ruby on Rails that will help you start with how to install Rails and set up your development environment to build your first web application. We’ll do this by simplifying technical terms so that you will not only learn how to program but also establish a strong base in “Rail” concepts.

What is Ruby on Rails? A Quick Brief

As discussed earlier, Rails is a Ruby-written type of web application development framework that seeks to smooth the programming of web applications by making some assumptions about what every developer needs before they start. By writing less than most languages and frameworks but achieving more, Rails allows the programmer to work more efficiently. In addition, experienced Rail developers claim that it makes the process of building web applications enjoyable.

Rails is opinionated software; it assumes that there is always one right way of doing things, thus encouraging this way. If you master “The Rails Way,”  you will experience tremendous productivity gains. Moreover, if you continue to bring old habits from other languages into your Rails development and try to apply patterns you have learned elsewhere, then you may not have much fun.

There are two main guiding principles behind the Rails philosophy:

DRY (Don’t Repeat Yourself): A principle in software development that states, every concept must be expressed only once in order to reduce ambiguity within the code base. By avoiding duplication, our code becomes less brittle, more maintainable, and easier to extend.

Convention Over Configuration: The Rails framework has opinions about the best approach to accomplishing many things, and defaults to these conventions rather than requiring the user to make endless configuration changes.

The benefits of using Ruby on Rails: 

• Simple to Learn
• Open Source with a Very Permissive License
• Extensive Libraries
• Highly Extensible
• Genuinely Object-Oriented
• Less Code, Fewer Bugs
• Supportive Community

Essential Basics To Learn About Rails

– Ruby Versions

In this Ruby on Rails tutorial, the first discussion is all about the importance of Ruby’s versions. There have been numerous individual Ruby version releases with various updates, functionalities, and other reasons. The first official version of Ruby on Rails was released in July 2004 (version 1.0) with its official launch, and the most recent launch to date is Ruby 3.3.4, released on July 9, 2024.

Rails requires Ruby version 2.7.0 or later to work effectively. However, technically, it can still function and work for big development and design trends with other older versions less than 2.7.0, but users might face issues related to security measures, and must require more community support including Ruby on Rails tutorials. 

How To Check Your Ruby Version:

As the version plays an important role, in this Ruby on Rails guide, we will learn the easiest way to check its version. 

To change the version, you need to open your terminal. This terminal is present under the name “Terminal” on macOS/Linux, and it is named “Command Prompt” on Windows.

After opening the terminal, type the command “ruby –version” and press enter. You’ll instantly see the installed Ruby version on your system. For instance, it appears as “ruby 2.7.0 (2023-12-25 revision 00000) [x86_64-linux],” where the first part (ruby 2.7.0) indicates the major and minor version numbers, followed by other aspects of the versions. 

Installation: Ruby On Rails Guide

For beginners, a Ruby on Rails tutorial for installation is essential. While there are several ways to do this, the easiest way is to install Ruby on the operating system you work with. For instance, both macOS/Linux and Windows have different ways. 

• For macOS/Linux:

You get a package manager with your macOS or linux shared hosting operating system. Using it is the easiest approach that offers high compatibility. You have to use different commands that vary depending on your distributions, like Debian/Ubuntu and CentOS/Red Hat/Fedora. 

• Debian/Ubuntu:

sudo apt update && sudo apt install ruby-full

• CentOS/Red Hat/Fedora:

sudo yum update && sudo yum install ruby ruby-devel

For Windows:

The Windows hosting operating system usually comes with a one-click installer that includes Ruby, development tools, and common RubyGems (Ruby libraries). Download the latest version from https://rubyinstaller.org/ and follow the installation wizard. That’s it!

Point to Note: 

Installing Ruby on your system and installing Ruby on Rails are different. As we already know, Rails is a framework of Ruby, hence, it becomes a prerequisite for Rails. After installing Ruby, you’ll need to install Rails itself using the gem install rails command.

Create A New Rails Project

To create a new project on your Ruby on Rails, you need to access the Rails command-line interface. Similar to the installation process, the procedure to create a new project on Ruby on Rails depends on your operating system. 

• For macOS/Linux:

Within the terminal, you get directories for various project needs. Navigate to your preferred directory in the terminal and run the command:

rails new project_name

Replace project_name with the desired name for your Rails application. Once the command is successfully run, it will create a new directory structure with all the necessary files, and your projects will successfully get started.

• For Windows:

Open your command prompt in your Windows operating system and search for “cmd.exe” in the start menu. Like Linux’s directory, Windows too has directories, so elect the directory using the cd command and run:

rails new project_name

Replace project_name with your desired name, just like in the above data.

Ruby On Rails Tutorial: Updating Rails

Updating your Ruby on Rails is easy, given that you have installed Rails using RubyGems. To update the rails, you can use a common command for both the Windows and Linux platforms. 

Type the command: 

tp> gem update rails

And press enter to run it. Once the command runs successfully, it will show the output. When you restart your app, it’ll pick up this latest version of Rails. Ensure that you are connected to the Internet while using this command.

Best Uses Of Ruby On Rails Tutorials
