Models Ruby On Rails

Learn how to use Ruby on Rails with an example of creating a simple web application.

Ruby on Rails Example

Ruby on Rails is an open source web application framework written in the Ruby programming language. It is designed to make programming web applications easier by making assumptions about what every developer needs to get started. Rails is a full-stack framework, providing default structures for a database, a web service, and web pages.

One of the most popular features of Rails is the ability to create a scaffold. This is a basic set of files and code that can be used to quickly create a web application. Scaffolding is a great way to get started because it provides a structure for the application. To illustrate, here is an example of creating a scaffold for a blog post:

$ rails generate scaffold Post title:string body:text

This command will generate a controller, model, view, and other related files for a blog post. It also creates the necessary migrations, which are files used to update the database schema.

Rails also provides a model-view-controller (MVC) framework, which is a design pattern for web applications. This pattern separates the application into three distinct layers: the model, which is responsible for data storage and retrieval; the view, which is responsible for rendering the user interface; and the controller, which is responsible for managing the interactions between the model and view.

Rails is also known for its convention over configuration approach. This means that developers don't need to explicitly configure every aspect of the application; instead, they can rely on the conventions that Rails provides. This makes it easier for developers to get up and running quickly with a new application.

Overall, Ruby on Rails is an excellent choice for developing web applications. Its scaffolding and convention over configuration approaches make it easy to get started, and its MVC framework is a great way to structure the application. With its vibrant community and active development, Rails is a great platform for creating modern web applications.
