Django error logging: adding request header, body and user information

Question

Looking for a way to add the header, body, and email address of a user to your error log along with an exception stack trace in my views.py

After cleaning the network for several hours, many suggested writing their own middleware, and some suggested writing this information into a separate journal. However, knowing where your code is mistakenly solves one part of the problem, determining which poor soul it affected and what request data was sent during this exception, takes a long way to fix the problem. Having this information in the same log file makes sense to me.

Currently on my view.py I have this simple setup:

from django.db.models import Min, Max, Q, F, Count, Sum
from django.db import connection
from django.conf import settings
from django.http import HttpResponse, HttpResponseRedirect
from myapp.models import *
import logging

logging.basicConfig(filename="errors.log",
                    level=logging.ERROR,
                    format='%(asctime)s: %(message)s')


def random_view(request):
    if request.user.is_authenticated() and request.user.is_active:
         # generic view code goes here.
    else:
        return HttpResponse(status=401)
