In this chapter, we improved our simple Django RESTful Web Service. We took advantage of many features included in the Django REST framework to remove duplicate code and to add many features for the web service. We just needed to edit a few lines of code to enable an important amount of features.

First, we took advantage of model serializers. Then, we understood the different accepted and returned content types and the importance of providing accurate responses to the HTTP OPTIONS requests.

We incorporated the @api_view decorator and made the necessary changes to the existing code to enable diverse parsers and renderers. We understood how things worked under the hood in the Django REST framework. We worked with different content types and noticed the improvement of the RESTful Web Service compared with its previous versions.

Now that we understand how easy it is to work with different content types with the Django REST framework, we will work with one of the most interesting and powerful features: the browsable API. We will cover this topic in Chapter 15, Understanding and Customizing the Browsable API Feature.
