How do I handle relationships in Django REST Framework serializers?

In Django REST Framework, you can handle relationships using fields like PrimaryKeyRelatedField, StringRelatedField, or SerializerMethodField. What specific relationship are you trying to implement?

I want to create a serializer for a model that has a foreign key relationship.

You can use PrimaryKeyRelatedField for foreign key relationships. For example, in your serializer, you can define it like this: related_model = serializers.PrimaryKeyRelatedField(queryset=RelatedModel.objects.all()). Would you like to see a complete example?

Yes, please provide a complete example.

Sure! Here's a simple example:

class BookSerializer(serializers.ModelSerializer):
    author = serializers.PrimaryKeyRelatedField(queryset=Author.objects.all())

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

This serializer allows you to link a book to an author using their primary key.
