Django Signal request_finished get user instanse

Question

I try to understand Signals in Django. I am creating project for DRF.

from django.dispatch import receiver
from django.contrib.auth.signals import user_logged_in
from django.core.signals import request_finished

For this Signal I can catch user

@receiver(user_logged_in)
def last_user_login(sender, request, user, **kwargs):
    print('User **{}** logged in'.format(user))

And I want to catch user for this signal, but it's impossible as I understood.

@receiver(request_finished)
def last_user_request(sender, **kwargs):
    print('User made request')

My target: catch last user request and write this data to db.

Could someone help me? Thanks.

write a custom middleware to achieve this:

middleware.py:

class SimpleMiddleware:
   def __init__(self, get_response):
        self.get_response = get_response
        # One-time configuration and initialization.
    
    def __call__(self, request):
        # Code to be executed for each request before
        # the view (and later middleware) are called.
    
        response = self.get_response(request)
    
        print(response.status_code)
        print(request.user.username)
        # Add user data in db....
        if request.method == 'POST':
            print(request.POST)
    
        # Code to be executed for each request/response after
        # the view is called.
    
        return response

settings.py:

MIDDLEWARE = [

    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',    
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
     
    'myproject.middleware.SimpleMiddleware',
