17.9. Views in Django: Creating APIs with Django Rest Framework
Django is a powerful web development tool that lets you create robust and efficient systems. With the Django Rest Framework (DRF), it is possible to create APIs (Application Programming Interface) that allow the interaction between different systems, making Django even more powerful. In this section, we'll cover how to create APIs with Django Rest Framework.
What is Django Rest Framework?
The Django Rest Framework is a powerful and flexible extension to Django that makes it easy to build APIs. It provides a range of functionality that lets you build APIs efficiently and effectively. With DRF, you can create APIs that can handle authentication, serialization, views, and routing, among other things.
Creating APIs with Django Rest Framework
Building APIs with the Django Rest Framework involves several steps. Let's cover each of them in detail.
Django Rest Framework Installation
Before you start creating APIs, you need to install the Django Rest Framework. This can be done using pip, which is a package manager for Python. The command to install DRF is: pip install djangorestframework.
Creating the Template
The next step is to create a template. The model is a representation of the database and defines the structure of the data that the API will handle. For example, if you're creating an API for a library management system, you might have one template for books, another for authors, etc.

Data Serialization
Once the model is ready, the next step is data serialization. Serialization is the process of transforming model data into a format that can be easily manipulated by the API. The Django Rest Framework provides an easy way to do this through Serializers.
Creating Views
With the model and serializers ready, the next step is to create the views. Views are responsible for handling HTTP requests and returning responses. In the Django Rest Framework, views can be created using ViewSets, which are classes that provide standard operations for listing, creating, retrieving, updating, and deleting objects.
Routing
The last step in creating an API with Django Rest Framework is routing. Routing is the process of defining how HTTP requests are matched to views. DRF provides a simple and easy-to-use router that allows you to define routes for views.
Conclusion
In summary, the Django Rest Framework is a powerful tool that makes creating APIs easy. With it, you can create robust and efficient APIs that can be used to interact with other systems. We hope this guide has helped you understand how to build APIs with the Django Rest Framework.
