How do Django serializers handle relationships between models?

How do Django serializers handle relationships between models?

Django serializers can handle relationships using fields like 'PrimaryKeyRelatedField', 'StringRelatedField', and 'Nested Serializers'. They allow you to represent related models in your serialized data.

Can you give me an example of using a nested serializer?

Sure! If you have a Book model with a foreign key to an Author model, you can create a nested serializer for Author and include it in the BookSerializer.

What if I want to include only specific fields from the related model?

You can specify the fields argument in the nested serializer to include only the fields you want. For example, AuthorSerializer(fields=['name']) will only include the author's name.

How do I handle many-to-many relationships?

For many-to-many relationships, you can use ManyRelatedField in your serializer. This allows you to serialize multiple related objects.
