Ruby on Rails Website Development: Building Dynamic Websites with Ease:

Welcome to the world of web development! In this age of advanced technology, creating dynamic websites has become a necessity for businesses and individuals alike. However, building a website from scratch can be a daunting task if you don’t have the right tools and frameworks at your disposal. That’s where Ruby on Rails comes in. Ruby on Rails, also known as Rails, is a powerful web application framework that simplifies the process of developing robust and scalable websites. Let’s dive into the world of Ruby on Rails website development and explore how it can help you create dynamic websites with ease.

Why Choose Ruby on Rails for Website Development:

When it comes to website development, there are numerous programming languages and frameworks available. So, why should you choose Ruby on Rails? The answer lies in its simplicity and productivity. Ruby on Rails follows the principle of “Convention over Configuration,” which means that it provides a set of sensible defaults and conventions that allow developers to focus on building the application rather than configuring every aspect of it. This approach significantly speeds up the development process and reduces the amount of code required.

Another reason to choose Ruby on Rails is its active and supportive community. The Rails community is vast and vibrant, with thousands of developers contributing to its growth and improvement. This means that whenever you encounter a problem or need guidance, you can rely on the community for support. Additionally, Ruby on Rails has a rich ecosystem of libraries and gems, which further enhances its capabilities and allows developers to add functionality to their websites with ease.

Getting Started with Ruby on Rails:

Before you can start building dynamic websites with Ruby on Rails, you need to set up your development environment. Here’s a step-by-step guide to get you started:

Step 1: Install Ruby and Rails

The first step is to install Ruby and Rails on your machine. Ruby is the programming language, and Rails is the framework built on top of it. Visit the official Ruby website ( and follow the installation instructions based on your operating system. Once you have Ruby installed, open your terminal and run the following command to install Rails:

gem install rails

This will install the latest version of Rails on your system.

Step 2: Create a New Rails Application

Now that you have Rails installed, you can create a new Rails application. Open your terminal and navigate to the directory where you want to create your project. Run the following command to generate a new Rails application:

rails new myapp

This will create a new Rails application named “myapp” in the current directory.

Step 3: Start the Rails Server

Once your application is created, navigate into the project directory by running the following command:

cd myapp

Now, start the Rails server by running the following command:

rails server

This will start the server, and you will be able to access your application on http://localhost:3000.

Building Dynamic Websites with Ruby on Rails:

Now that you have your development environment set up, let’s dive into building dynamic websites with Ruby on Rails. Ruby on Rails follows the Model-View-Controller (MVC) architectural pattern, which separates the application logic into three components: models, views, and controllers. This separation of concerns allows for better organization and maintainability of the codebase.


In Ruby on Rails, models represent the business logic and data of your application. They interact with the database and encapsulate the rules and operations related to the data. To create a new model, you can run the following command in your terminal:

rails generate model Product name:string price:decimal

This command will generate a new model named “Product” with two attributes: “name” of type string and “price” of type decimal.

Once the model is generated, you can define associations with other models, validations, and custom methods. For example, you can define a one-to-many association between the Product model and the Order model by adding the following code to the respective model files:

class Product < ApplicationRecord
  has_many :orders

class Order < ApplicationRecord
  belongs_to :product

This allows you to easily retrieve all the orders associated with a product or the product associated with an order.


Views in Ruby on Rails are responsible for presenting the data to the users. They are written in HTML with embedded Ruby code (ERB) to dynamically generate the content. Rails provides a powerful view templating system that allows you to reuse code and separate the presentation logic from the application logic.

To create a new view, you can generate a controller and its associated views by running the following command:

rails generate controller Products

This will generate a new controller named “Products” and its associated views in the “app/views/products” directory.

In the view file, you can use HTML, CSS, and JavaScript to structure and style the content. You can also embed Ruby code using ERB syntax to dynamically generate the content based on the data from the controller.


Controllers in Ruby on Rails handle the incoming requests and coordinate the actions between the models and views. They are responsible for processing the user input, interacting with the models to retrieve and manipulate data, and rendering the appropriate views.

To generate a new controller, you can run the following command:

rails generate controller Products

This will generate a new controller named “Products” in the “app/controllers” directory.

In the controller file, you define actions that correspond to different routes and handle the logic for each action. For example, you can define an “index” action that retrieves all the products from the database and renders the “index” view:

class ProductsController < ApplicationController
  def index
    @products = Product.all

The “@products” instance variable is then accessible in the corresponding view, allowing you to display the data dynamically.


Routing in Ruby on Rails maps incoming requests to the appropriate controller actions. It defines the URL structure of your application and determines how the requests should be handled.

Rails uses a file named “routes.rb” in the “config” directory to define the routes. You can specify the routes manually or use shorthand methods provided by Rails. For example, to define a route for the “index” action of the “Products” controller, you can add the following line to the “routes.rb” file:

get '/products', to: 'products#index'

This maps the URL “http://localhost:3000/products” to the “index” action of the “Products” controller.


Congratulations! You’ve taken your first steps into the world of Ruby on Rails website development. Ruby on Rails provides a powerful and efficient framework for building dynamic websites, enabling you to focus on the application logic rather than the configuration. By following the MVC pattern, you can organize your code and create scalable and maintainable web applications.

Remember, practice makes perfect. The more you dive into Ruby on Rails, the better you’ll become at crafting amazing websites. So, roll up your sleeves, unleash your creativity, and start building dynamic websites with Ruby on Rails today!. For more visit Techy Robo.
