Web Development Magic with Ruby on Rails MVC Framework

by Nitish Bhardwaj Manager - Web and App Developer

Delve into the world of Ruby on Rails, a web development framework renowned for its simplicity and productivity. Uncover the power of the Model-View-Controller (MVC) architecture, a key feature that brings order to your code, making it clean and maintainable. Let's break down the basics for beginners.

Understanding Ruby On Rails Model-View-Controller (MVC) Framework:

1. Model:

Imagine the Model as the brains orchestrating your application. It's not just a data storage space; it's the genius behind the scenes, handling the logic seamlessly. In a blogging website example, the Model manages blog posts, comments, and user data. It acts like an organized librarian, ensuring data is well-kept and operations run smoothly.

Here's a simple example of a Book model in Ruby:

class Book
  attr_accessor :title, :author, :status

  def initialize(title, author, status = "available")
    @title = title
    @author = author
    @status = status
  end

  def reserve
    if @status == "available"
      @status = "reserved"
      true
    else
      false
    end
  end

  def return_book
    if @status == "reserved"
      @status = "available"
      true
    else
      false
    end
  end
end

2. View:

The View is the friendly face of your application, presenting data in an easily understandable format. It's like the storyteller, crafting an engaging tale for users. In a web page example, the View displays a list of books.

Here's an example of a simple View for displaying a list of books in HTML:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Library</title>
</head>
<body>
  <h1>Books</h1>
  <ul>
    <% books.each do |book| %>
      <li><%= book.title %> by <%= book.author %></li>
    <% end %>
  </ul>
</body>
</html>

3. Controller:

The Controller acts as the mediator, ensuring smooth communication between the Model and the View. It's like a friendly guide translating user input into actions. In a library application, the Controller manages actions like displaying all books, searching, and reserving a book.

Here's an example of a simple Controller for our library application in Ruby:

class LibraryController
  def index
    @books = Book.all
    render "index"
  end

  def search(query)
    @books = Book.search(query)
    render "search_results"
  end

  def reserve(book_id)
    book = Book.find(book_id)
    if book.reserve
      render "reserve_success"
    else
      render "reserve_failure"
    end
  end
end

Advantages of MVC in Ruby on Rails:

Modularity:

MVC brings a modular code structure, enhancing understandability and maintenance. Just like organizing kitchen tools, MVC neatly separates code into Models, Views, and Controllers, making the application more organized and easier to manage.

Scalability:

The MVC structure facilitates seamless scalability, allowing for easy addition of new features without disrupting the existing codebase.

Code Reusability:

MVC promotes code reuse, allowing components to be utilized in different parts of the application, reducing redundancy and saving time.
