ViewSet

A viewset is a concept found in some web framework architectures, most notably in Django Rest Framework (DRF). It essentially groups together related views into a single class. Instead of defining separate view functions or classes for different HTTP methods (GET, POST, PUT, DELETE) acting on a particular resource or set of resources, a viewset consolidates these into one unit.

For example, a `UserViewSet` might handle all operations related to user accounts. A single GET request could list all users, while another GET request to a specific user's URL might retrieve their details. A POST request to the same URL might create a new user, and a PUT or PATCH request would update an existing user. A DELETE request would remove a user.

This approach promotes code organization and reduces redundancy. By mapping URL patterns to a viewset, the framework can automatically generate the necessary routes for all the actions supported by the viewset. This is often achieved through the use of routers in DRF, which introspect the viewset and create the appropriate URL configurations. This convention simplifies the development process, especially for common CRUD (Create, Read, Update, Delete) operations on resources.
