Summary

In this chapter, we learned how to work with DRF Serializers. First, we explored the concept of a basic DRF Serializer, as well as how DRF uses a Renderer and a Parser to transform data from JSON to Python native datatypes (and vice-versa). Then, we learned how to use DRF ModelSerializer with Django models.

DRF Serializers provide data validation support out of the box. In this chapter, we learned different ways to integrate field-level and object-level validation using serializers. We also learned how we can integrate DRF Serializers to work with Django-related fields and use nested Serializers.

Finally, we learned how to integrate DRF Serializers with DRF views to get an end-to-end picture of how Serializers work in the overall application development.

In the next chapter, we shall learn how we can use Django admin and work with Django management commands.
