Middleware Setup

I am trying to setup a message middleware for my marketing app,but the method process_request is not returning anything. it is running without errors still though not returning message requests.

my middleware.py---

from .models import MarketingMessage

class DisplayMarketing():
    def __init__(self, get_response):
        self.get_response = get_response
    def __call__(self, request):
        def process_request(request):
            print("something")
            try:
                request.session['marketing_message'] = MarketingMessage.objects.all()[0].message
            except:
                request.session['marketing_message']  = False
        response = self.get_response(request)
        return response

my 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',
    'marketing.middleware.DisplayMarketing',
]

if you use middleware mixin process_request will automatically called.

try 

from django.utils.deprecation import MiddlewareMixin

class DisplayMarketing(MiddlewareMixin):

    def __init__(self, get_response):
        self.get_response = get_response

    def process_request(self, request):
            print("something")
            try:
                request.session['marketing_message'] = "bossk"
            except:
                request.session['marketing_message']  = False

or, other wise you have call process_request manually 

from .models import MarketingMessage

class DisplayMarketing():
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        def process_request(request):
            print("something")
            try:
                request.session['marketing_message'] ="bossk"
            except:
                request.session['marketing_message']  = False
        response = self.get_response(process_request(request))
        return response
