What are some serialization techniques in Django REST Framework?

Django REST Framework (DRF) offers several serialization techniques, including ModelSerializer, Serializer, and custom serializers. ModelSerializer automatically creates fields based on your model, while Serializer allows for more control over the serialization process.

Can you explain the difference between ModelSerializer and Serializer?

Sure! ModelSerializer is a shortcut that automatically creates a serializer class based on a Django model, handling fields and validation for you. On the other hand, Serializer gives you more flexibility to define fields and validation manually.

How do I create a custom serializer?

To create a custom serializer, you can subclass serializers.Serializer and define your fields as class attributes. You can also implement custom validation methods to handle specific validation logic.

What are some common use cases for serializers?

Common use cases include converting complex data types like querysets and model instances into JSON, validating incoming data, and transforming data for API responses.
