Django comes with a robust authentication system that handles both authentication and authorization. In this post let's talk about two of its methods
The authenticate method is used to verify the user's credentials against the authentication backends defined in the project. it takes the user's credentials as arguments and returns user object if the credentials are valid and if the credentials are invalid then it returns
login() function is used to create user sessions and log them in. It takes a
HttpRequest object and a User object saves the user's ID in the session using Django’s session framework and sets a session cookie in the user's browser, allowing them to remain authenticated across different pages and requests.
Example to create a login_view using both methods
from django.contrib.auth import authenticate, login from django.http import HttpResponse from django.shortcuts import render from django.contrib.auth.models import User def login_view(request): if request.method == 'POST': username = request.POST['username'] password = request.POST['password'] user = authenticate(request, username=username, password=password) if user is not None: login(request, user) return HttpResponse("Logged in successfully") else: return HttpResponse("Authentication failed. Please try again.") return render(request, 'login.html')
