How Ruby on Rails Uses the Model-View-Controller (MVC) Framework

Ruby on Rails is a web application framework that follows the Model-View-Controller (MVC) architectural pattern. The MVC pattern separates an application's data, user interface, and control logic into three interconnected components: the Model, the View, and the Controller. Here's how Ruby on Rails utilizes this framework:

Model

The Model in Ruby on Rails represents the data and the business logic of the application. It is responsible for managing the data, validating it, and enforcing business rules. Models interact with the database using Active Record, Rails' built-in Object-Relational Mapping (ORM) layer. Active Record provides methods for creating, reading, updating, and deleting data, as well as defining relationships between models.

View

The View in Ruby on Rails is responsible for rendering the user interface and presenting data to the user. Views are typically written in HTML with embedded Ruby code (ERB) or using a templating engine like Haml or Slim. Views can access data from the Model and use it to generate dynamic content. They also handle user interactions, such as form submissions and link clicks, and pass the data to the Controller.
