How do I use nested serializers in Django REST Framework?

To use nested serializers in Django REST Framework, you can define a serializer for the nested model and include it in the parent serializer.

Can you show me an example of a nested serializer?

Sure! If you have a Book model and an Author model, you can create an AuthorSerializer and then include it in the BookSerializer.

What if I want to create or update nested objects?

You can override the create and update methods in your parent serializer to handle the nested objects accordingly.

Are there any performance considerations I should be aware of?

Yes, using nested serializers can impact performance, especially with large datasets. Consider using select_related or prefetch_related to optimize queries.
