What does the acronym MVC stand for in the context of Rails?
Risposta
MVC stands for Model-View-Controller, an architectural pattern that separates the application into three interconnected components. The Model handles data and business logic, the View displays the user interface, and the Controller orchestrates interactions between the two. This separation facilitates code maintenance and testing.

What is the main role of the Model in Rails MVC architecture?
Risposta
In Rails, the Model represents application data and encapsulates business logic. It interacts with the database via ActiveRecord, manages validations, entity associations, and callbacks. The Model is responsible for data integrity and business rules, independent of the user interface.
3What does the 'Convention over Configuration' principle mean in Rails?
What does the 'Convention over Configuration' principle mean in Rails?
Risposta
Convention over Configuration means Rails provides sensible defaults for most aspects of the application. If developers follow naming and structure conventions, Rails automatically configures connections between models, controllers and views. This reduces boilerplate code and accelerates development.

Which directory contains view templates in a Rails application?
