Using python async await with django restframework
Download this code from https://codegive.com
Asynchronous programming in Python has become increasingly popular, especially with the advent of the asyncio module. Django, a powerful web framework for Python, also supports asynchronous views starting from version 3.1. In this tutorial, we'll explore how to use async/await with Django Rest Framework (DRF) to build asynchronous APIs.
Make sure you have the following installed:
Let's start by creating a new Django project and a Django app:
Now, add rest_framework and async_drf_tutorial.async_api to your INSTALLED_APPS in settings.py:
Create a new file views.py inside the async_api app:
This view contains an asynchronous function (async_task) that simulates an asynchronous task, such as making an async database query or fetching data from an external API.
Configure the URLs to include the new view in urls.py:
Include these URLs in the main urls.py:
Run the Django development server:
Visit http://127.0.0.1:8000/api/async/ in your browser or use a tool like curl or httpie to make a request:
You should receive a response after a 2-second delay.
In this tutorial, we explored how to use async/await with Django Rest Framework to create asynchronous views. This can be particularly useful when dealing with I/O-bound tasks to improve the responsiveness and scalability of your Django application. Experiment with more complex asynchronous tasks and integrate them into your asynchronous views to harness the full power of asynchronous programming in Django.
