✅

Since you are using the new MIDDLEWARE settings, your Middleware class must accept a get_response argument: https://docs.djangoproject.com/en/1.10/topics/http/middleware/#writing-your-own-middleware

You could write your class like this:

from django.http import HttpResponse

class ExceptionMiddleware(object):
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        return self.get_response(request)

    def process_exception(self, request, exception): 
        return HttpResponse("in exception")

You could also use the MiddlewareMixin to make your Middleware compatible with pre-1.10 and post-1.10 Django versions: https://docs.djangoproject.com/en/1.10/topics/http/middleware/#upgrading-pre-django-1-10-style-middleware

from django.http import HttpResponse
from django.utils.deprecation import MiddlewareMixin

class ExceptionMiddleware(MiddlewareMixin):
    def process_exception(self, request, exception):
        return HttpResponse("in exception")

in the newer version of Django, the middleware should be written like this 

import datetime
from django.core.cache import cache
from django.conf import settings
from django.utils.deprecation import MiddlewareMixin

class ActiveUserMiddleware(MiddlewareMixin):

    def process_request(self, request):
        current_user = request.user
        if request.user.is_authenticated:
            now = datetime.datetime.now()
            cache.set('seen_%s' % (current_user.username), now, 
                           settings.USER_LASTSEEN_TIMEOUT)
