MVC in Ruby on Rails

Have you heard about the Model-View-Controller (MVC) architecture but are not sure what it means? Do not worry, you are not alone! In this article, we will take a look at what the MVC architecture is and how it works in Ruby on Rails.

Think of building a website like building a house. Just like a house has a kitchen, living room, bedrooms, etc., a website also has different components such as databases, HTML templates, and more. In the MVC architecture, these different components are separated into three main parts:

Model: The model represents the data of your website, like the database that stores information about your users, products, and more.

View: The view is what the user sees on the screen, like the HTML templates that display the information from the database.

Controller: The controller acts as a mediator between the model and the view. It takes the data from the model and passes it to the view, which then displays it to the user. It also takes the user's inputs and passes it back to the model for processing.

Let's take an example of an online store to understand this better. The model will represent the products that are available for sale in the store. The view will show the products to the user, and the controller will handle the process of adding the product to the cart and taking the payment.

By separating these components, it makes the code more organised and easy to maintain. If you need to make changes to the product information, you only need to update the model, and the changes will automatically be reflected in the view.

In Ruby on Rails, the MVC architecture is implemented by default, which makes it easier for developers to create and maintain web applications. The framework takes care of connecting the model, view, and controller, so the developer can focus on writing the code for each component.

In conclusion, the MVC architecture is a crucial concept for web development, and it is used in many popular web frameworks, including Ruby on Rails. By understanding how it works, you will be able to build better and more organised web applications.

I hope this article has helped you understand the MVC architecture and how it works in Ruby on Rails. If you have any questions, feel free to ask!
