Greetings

Django: 3.1.7
OS: Windows 10 - 64 bit
Python: 3.8.6 - 64 bit

Project Name: coffehouse
App Names: about, stores, coffe_app

I was creating a custom middleware for my django project. And after adding
the path of middleware file to settings.py file (in MIDDLEWARE variable),
I got error below:

{{{
raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: WSGI application
'coffehouse.wsgi.application' could not be loaded; Error importing module.
}}}

#### settings.py:

{{{
INSTALLED_APPS = [
'coffe_app.apps.CoffeAppConfig',
'stores',
'about',

'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]

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',

'coffehouse.utils.middleware.CoffehouseMiddleware', <===
]

}}}

#### coffehouse\coffehouse\utils\middleware\CoffehouseMiddleware.py:

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

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

def process_view (self, request, view_func, view_args, view_kwargs):
pass

def process_exception (self, request, exception):
pass

def process_template_response (self, request, response):
pass
}}}

#### wsgi.py:

{{{
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'coffehouse.settings')
application = get_wsgi_application()
}}}
