How do I handle nested relationships in Django serializers?

To handle nested relationships in Django serializers, you can use the Serializer class to define nested serializers.

Can you give me an example of a nested serializer?

Sure! If you have a Book model with a foreign key to an Author, you can create an AuthorSerializer and use it in your BookSerializer.

What if I want to create or update nested relationships?

You can override the create and update methods in your serializer to handle nested data appropriately.

Are there any performance considerations I should be aware of?

Yes, be cautious with deep nesting as it can lead to performance issues. Use select_related and prefetch_related to optimize queries.
