check auth user django

You can check if a user is authenticated in Django using the is_authenticated attribute of the User object. Here's an example of how to use it:

from django.contrib.auth.decorators import login_required
from django.http import HttpResponse

@login_required
def my_view(request):
    if request.user.is_authenticated:
        # User is authenticated
        return HttpResponse("You are authenticated")
    else:
        # User is not authenticated
        return HttpResponse("You are not authenticated")

In this example, the @login_required decorator ensures that the user is authenticated before the my_view function is called. Inside the function, request.user.is_authenticated is used to check if the user is authenticated. If the user is authenticated, the function returns a response indicating that the user is authenticated. If the user is not authenticated, a different response is returned.
