consider using genericapiview as view base class

Here's a breakdown of the advantages:

1. Reduced Boilerplate Code (DRY - Don't Repeat Yourself):

   Pre-built functionality: GenericAPIView extends APIView and provides a lot of commonly required behavior out of the box. This includes:

   Methods for working with querysets (get_queryset(), queryset attribute).
   
   Methods for interacting with serializers (get_serializer(), serializer_class attribute).
   
   Support for pagination, filtering, and lookup fields (like pk).
   
   Error handling for common scenarios (e.g., 404 Not Found).
   

   Mixins: GenericAPIView is designed to be used with DRF's mixin classes (e.g., ListModelMixin, CreateModelMixin, RetrieveModelMixin, UpdateModelMixin, DestroyModelMixin). These mixins provide the core logic for specific CRUD operations. By combining GenericAPIView with appropriate mixins, you can create fully functional API views with very little code.

2. Consistency and Predictability:

   Standardized structure: By using GenericAPIView and its associated patterns, your API endpoints will have a more consistent and predictable structure. This makes your codebase easier to understand, maintain, and for other developers to work with.

   DRF's conventions: It aligns your views with DRF's best practices and conventions, leveraging the framework's power rather than reinventing the wheel.

3. Easier Customization and Extension (when needed):

   Overridable methods: While GenericAPIView provides a lot of default behavior, it also offers well-defined methods (get_queryset, get_serializer_class, perform_create, perform_update, perform_destroy, etc.) that you can easily override to implement custom logic. This allows you to tailor the behavior without completely ditching the benefits of generic views.

   Dynamic behavior: You can dynamically change the queryset or serializer class based on the request (e.g., different serializers for read/write, or based on user roles).

4. Clearer Separation of Concerns:

   GenericAPIView encourages a cleaner separation between concerns. Your view primarily defines which model and serializer it's working with, and the mixins handle the specific HTTP method logic.

5. Better Integration with DRF Features:

   GenericAPIView seamlessly integrates with other DRF features like:

   Pagination: Easily apply pagination to list views.
   
   Filtering: Use DRF's filter backends for advanced data filtering.
   
   Permissions and Authentication: Apply permission and authentication classes directly to the view.
   

When to use GenericAPIView (and its concrete subclasses):

Common CRUD operations: If your API endpoint primarily performs standard create, retrieve, update, or delete operations on a single database model.

Rapid development: When you want to quickly build API endpoints with minimal code.

Maintainability: To create a more maintainable and consistent codebase.
