How do I handle model relationships in Django serializers?

In Django, you can handle model relationships in serializers using nested serializers or by using the PrimaryKeyRelatedField. Would you like to see an example?

Yes, please provide an example of a nested serializer.

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

Can you show me the code for that?

Absolutely! Here's a simple example:

class AuthorSerializer(serializers.ModelSerializer):
    class Meta:
        model = Author
        fields = ['id', 'name']

class BookSerializer(serializers.ModelSerializer):
    author = AuthorSerializer()

    class Meta:
        model = Book
        fields = ['id', 'title', 'author']
