Serialization is one of the most important concepts in RESTful Webservices. It facilitates the conversion of complex data (such as model instances) to native Python data types that can be rendered using JSON, XML, or other content types. In Django REST Framework, we have different types of serializers to serialize object instances, and the serializers have different serializer relations to represent model relationships. In this section, we will discuss the different serializer relations provided by Django REST Framework Serializers.
Before working on Django REST Framework serializers, you should make sure that you already installed Django and Django REST Framework in your virtual environment. You can check the below tutorials:
Next, you can create a project named emt (employee management tool) and an app named employees. Refer to the following articles to check how to create a project and an app in Django.
In this section, we will be using PostgreSQL. You have to create a database named emt in PostgreSQL. You can check the below link for installation.
Note: if you need to work with SQLite, you can continue using the default database.
To make use of PostgreSQL, we need to install a Python-PostgreSQL Database Adapter (psycopg2). This package helps Django to interact with a PostgreSQL database. You can use the below command to install the psycopg2 package. Make sure the PostgreSQL bin folder is included in the PATH environmental variables, and the virtual environment is activated before executing the command.
pip install psycopg2

I will be using the Django REST Framework to build a complete REST API is this livestream.
In this post, we'll discuss about Django Rest Framework or DRF. DRF is used to create RESTful APIs in Django which later could be consumed by various apps; mobile, web, desktop, etc. We will be discussing how to install DRF on your machine and then will be writing our APIs for a system.
This article is a definitive guide for starters who want to develop projects with RESTful APIs using Python, Django and Django Rest Framework.
