Ruby On Rails-Ruby on Rails development framework.

Example

Rails follows the Model-View-Controller (MVC) pattern, where the model handles data and business logic, the view manages the display and presentation, and the controller responds to user input, typically in the form of HTTP requests.

Scenario

In a blogging application, the model would manage the data for blog posts, the view would render the post content to the user, and the controller would manage the flow of information between the model and the view, such as fetching a blog post from the database and passing it to the view for display.

Example

Rails provides a RESTful interface, meaning it maps HTTP verbs (GET, POST, PUT, DELETE) to CRUD (Create, Read, Update, Delete) operations on resources like models.

Scenario

In an e-commerce application, RESTful routing allows Rails to map the actions of listing products, showing a specific product, creating a new product, updating product details, and deleting a product to standard HTTP routes like /products, /products/:id, /products/new, etc.

Example

Active Record is the ORM (Object-Relational Mapping) layer in Rails that facilitates database interactions, allowing developers to interact with the database using Ruby objects rather than raw SQL queries.

Scenario

In a social networking site, a 'User' model could be created with Active Record, which automatically generates methods for creating, reading, updating, and deleting user data in the database, such as `User.create`, `User.find`, `User.update`, and `User.destroy`.
