Can an app subclass a core django class to channge its behavior

[Mike Oliver]

Hello, 

I want to follow a microservices architecture and have some shared services I can include in a process flow instead of the 1:1 View:Model 

Suggestions?

Could you tell us more detail of process flow?

Well I have continued to search and now I see that CustomMiddleware will do what I want, but I cannot find a current example and some of the StackOverflow answers are old and not working in the latest Django.

Currently, I have 

/mysite/

    mymiddleware.py

   settings.py

My CustomMiddlware class looks like...

class DoseControllerMiddleware(object):

    def process_request(self, request):

        """

        get ready to call the Dose Controller

        """

        print("DoseControllerModdleware.process_request Hooray")

        return None

my settings has...

MIDDLEWARE = [

    'django.middleware.security.SecurityMiddleware',

    'django.contrib.sessions.middleware.SessionMiddleware',

    'mysite.mymiddleware.DoseControllerMiddleware',

    'django.middleware.common.CommonMiddleware',

    'django.middleware.csrf.CsrfViewMiddleware',

    'django.contrib.auth.middleware.AuthenticationMiddleware',

    'django.contrib.messages.middleware.MessageMiddleware',

    'django.middleware.clickjacking.XFrameOptionsMiddleware',

]

runserver gives me...

ModuleNotFoundError: No module named 'mysite.mymiddleware'

Ur config with me are the same.

But i put it in the bottom of the middleware

MIDDLEWARE = [
    "django.middleware.security.SecurityMiddleware",
    "whitenoise.middleware.WhiteNoiseMiddleware",
    "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",

    "chuthe.middlewares.supervisor.ChutheIOMiddleware",
]

Think you should try by shell to make sure you can call it, or importable `from mysite.mymiddleware import DoseControllerMiddleware`. Shell very helpful.

Ok will try the shell

[Mike Oliver]

>>> import mysite.mymiddleware.DoseControllerMiddleware
Traceback (most recent call last):
  File "<console>", line 1, in <module>

ModuleNotFoundError: No module named 'mysite.mymiddleware'

>>> import mymiddleware.DoseControllerMiddleware
Traceback (most recent call last):
  File "<console>", line 1, in <module>
ModuleNotFoundError: No module named 'mymiddleware'
>>>
