MVC | Ruby on Rails

The Model-View-Controller (MVC) template concept is key to understanding the architecture of Ruby on Rails. It allows separating different aspects of web applications and ensures a simpler and more structured program development.

The use of MVC approach allows breaking down a program into parts, which improves code organization and reduces the likelihood of errors. Applying this concept enables better code portability across different projects and makes it more accessible for understanding and development by teams of developers.

In the development of programs with Ruby on Rails, using the MVC approach is essential. Developers can easily create and extend program functionality as they can work with each component separately, without worrying about developing other parts of the application. This increases developers' productivity and reduces program development time.

Overall, the use of the Model-View-Controller (MVC) template concept allows Ruby on Rails program developers to maintain a more organized and structured code. This provides convenience in program development and reduces debugging time and error searching costs. Additionally, the use of MVC makes it easier to test individual application components and ensures greater program scalability.

When developing programs using the MVC approach in Ruby on Rails, developers face several tasks. One of the main aspects involves defining the logic and structure of models.

Models (Model) are responsible for interacting with the database and ensuring the application's logic. Their main tasks include data persistence, validation, and proper functioning of the application's business logic.

Views on the other hand are responsible for displaying the data collected by the model. They provide users with the ability to interact with the application and display various user activity results.

Controllers serve as an intermediate interface between models and views. They handle user requests, execute application logic, and send data to the appropriate views for display.

Adhering to MVC principles facilitates easy modification of individual program components, ensures high scalability, and enables convenient testing.
