What are some advanced usage patterns for Django serializers?

Django serializers can be used in various advanced ways, such as nested serializers, custom validation, and dynamic fields. Would you like to explore any specific pattern?

Can you explain how to use nested serializers?

Sure! Nested serializers allow you to represent relationships between models. For instance, if you have a Book model with an Author model, you can create a nested serializer for the author within the book serializer.

How do I implement custom validation in a serializer?

You can implement custom validation by overriding the validate method in your serializer class. This allows you to add specific checks for your fields.

What are dynamic fields in serializers?

Dynamic fields let you control which fields are included in the serialized output based on the request or context. You can achieve this by overriding the __init__ method.
