The solution proposed by @nKn is good starting point, but when I tried to implemented today, I faced two issues:

1. In the current Django version middleware created as plain object doesn't work.
2. Unittests are failing (since they usually run in single thread, so your 'request' will can be sticked between two consequent tests if the first test has HTTP-request and the second hasn't).

Here is my updated middleware code, which works with Django 1.10 and doesn't break unittests:

from threading import current_thread

from django.utils.deprecation import MiddlewareMixin


_requests = {}


def current_request():
    return _requests.get(current_thread().ident, None)


class RequestMiddleware(MiddlewareMixin):

    def process_request(self, request):
        _requests[current_thread().ident] = request

    def process_response(self, request, response):
        # when response is ready, request should be flushed
        _requests.pop(current_thread().ident, None)
        return response

    def process_exception(self, request, exception):
        # if an exception has happened, request should be flushed too
         _requests.pop(current_thread().ident, None)
