How can I use Django's ModelSerializer for complex data structures?

You can use Django's ModelSerializer to handle complex data structures by defining nested serializers. This allows you to serialize related models.

Can you show 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 include only specific fields from the nested serializer?

You can specify the fields you want to include in the nested serializer by using the fields attribute in the Meta class.

Is it possible to validate nested data?

Yes, you can override the create and update methods in your serializer to add custom validation for nested data.
