Using Django DRF JWT Authentication with Django Channels

Sending the token over WebSocket from client to server

This step assumes that -

  • User is already authenticated to use Django DRF using JWT
  • A token is present on client side

We can only make use of querystring to send the token while opening the socket.

Create a new WebSocket using the endpoint -

// Retrieve your token on client side
let token = retrieveToken()
let endpoint = "ws://yourwebsite.com/path/"
// Create new WebSocket
let socket = new WebSocket(endpoint + "?token=" + token)

Handling the token and authenticating the user

To authenticate the user in Channels using JWT, we will need to create a custom authentication middleware for Channels. Make a file yourproject/channelsmiddleware.py -

from django.db import close_old_connections
from rest_framework_simplejwt.tokens import UntypedToken
from rest_framework_simplejwt.exceptions import InvalidToken, TokenError
from jwt import decode as jwt_decode
from django.conf import settings
from django.contrib.auth import get_user_model
from urllib.parse import parse_qs
class TokenAuthMiddleware:
    Custom token auth middleware
    def __init__(self, inner):
        # Store the ASGI application we were passed
        self.inner = inner
    def __call__(self, scope):
        # Close old database connections to prevent usage of timed out connections
        # Get the token
        token = parse_qs(scope["query_string"].decode("utf8"))["token"][0]
        # Try to authenticate the user
            # This will automatically validate the token and raise an error if token is invalid
        except (InvalidToken, TokenError) as e:
            # Token is invalid
            return None
            #  Then token is valid, decode it
            decoded_data = jwt_decode(token, settings.SECRET_KEY, algorithms=["HS256"])
            # Will return a dictionary like -
            # {
            #     "token_type": "access",
            #     "exp": 1568770772,
            #     "jti": "5c15e80d65b04c20ad34d77b6703251b",
            #     "user_id": 6
            # }
            # Get the user using ID
            user = get_user_model().objects.get(id=decoded_data["user_id"])
        # Return the inner application directly and let it run everything else
        return self.inner(dict(scope, user=user))

Now use this middleware in yourproject/routing.py file -

from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
import yourapp.routing
from .channelsmiddleware import TokenAuthMiddleware
application = ProtocolTypeRouter(
        # (http->django views is added by default)
        "websocket": TokenAuthMiddleware(

 Accessing the User in consumer

You can now access the user in yourapp/consumers.py like -

from channels.generic.websocket import AsyncWebsocketConsumer
class FooConsumer(AsyncWebsocketConsumer):
    async def websocket_connect(self, event):
        user = self.scope[“user”]
        await self.accept()

Python FTW!

How model queries work in Django

How model queries work in Django

Welcome to my blog, hey everyone in this article we are going to be working with queries in Django so for any web app that you build your going to want to write a query so you can retrieve information from your database so in this article I’ll be showing you all the different ways that you can write queries and it should cover about 90% of the cases that you’ll have when you’re writing your code the other 10% depend on your specific use case you may have to get more complicated but for the most part what I cover in this article should be able to help you so let’s start with the model that I have I’ve already created it.

**Read More : **How to make Chatbot in Python.

Read More : Django Admin Full Customization step by step

let’s just get into this diagram that I made so in here:

django queries aboutDescribe each parameter in Django querset

we’re making a simple query for the myModel table so we want to pull out all the information in the database so we have this variable which is gonna hold a return value and we have our myModel models so this is simply the myModel model name so whatever you named your model just make sure you specify that and we’re gonna access the objects attribute once we get that object’s attribute we can simply use the all method and this will return all the information in the database so we’re gonna start with all and then we will go into getting single items filtering that data and go to our command prompt.

Here and we’ll actually start making our queries from here to do this let’s just go ahead and run** Python manage.py shell** and I am in my project file so make sure you’re in there when you start and what this does is it gives us an interactive shell to actually start working with our data so this is a lot like the Python shell but because we did manage.py it allows us to do things a Django way and actually query our database now open up the command prompt and let’s go ahead and start making our first queries.

How To Set Up Two-Factor Authentication in cPanel

What is 2FA
Two-Factor Authentication (or 2FA as it often referred to) is an extra layer of security that is used to provide users an additional level of protection when securing access to an account.
Employing a 2FA mechanism is a vast improvement in security over the Singe-Factor Authentication method of simply employing a username and password. Using this method, accounts that have 2FA enabled, require the user to enter a one-time passcode that is generated by an external application. The 2FA passcode (usually a six-digit number) is required to be input into the passcode field before access is granted. The 2FA input is usually required directly after the username and password are entered by the client.

REST Implementation Of Django Authentication System for Python


REST implementation of Django authentication system. djoser library provides a set of Django Rest Framework views to handle basic actions such as registration, login, logout, password reset and account activation. It works with custom user model.

Instead of reusing Django code (e.g. PasswordResetForm), we reimplemented few things to fit better into Single Page App architecture.

Developed by SUNSCRAPERS with passion & patience.


To be able to run djoser you have to meet following requirements:

  • Python (3.6, 3.7, 3.8, 3.9)
  • Django (2.2, 3.1)
  • Django REST Framework 3.11.1

If you need to support other versions, please use djoser<2.


Simply install using pip:

$ pip install djoser

And continue with the steps described at configuration guide.

JWT Authentication using Vue.js and Django

In this video tutorial, We'll learn JWT Authentication using Vue.js and Django. JWT is a short-lived token issued by server for clients to authenticate themselves without having to maintain an active session.
