Django Channels is not taking over deployment server

I am attempting Django Channels for the first time. I am following this tutorial - https://www.youtube.com/watch?v=cw8-KFVXpTE&t=21s - which basically explains Channels basics. I installed Channels in my virual environment using pip install channels and it installed the latest version, which is 4.0.0. I have laid out the basic setup. But when I run python manage.py runserver, I get -
Watching for file changes with StatReloader

Django version 4.1.3, using settings 'BrokerBackEnd.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.
when I shoul be getting this -

Starting ASGI/Channels version 4.0.0 development server at http://127.0.0.1:8000/

I cannot figure out what I might be doing wrong here and I cannot find any relevant solution anywhere. I would really appreciate any suggestions anyone might have.

As of django-channels 4.0.0 the daphne server was decoupled from the rest of channels. Now, you need to include daphne in your settings.py INSTALLED_APPS if you wish to use it. Include this at the top of your installed apps. The tutorial you are looking at uses an older version of channels.
INSTALLED_APPS = [
'daphne',
'channels',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'corsheaders',
'rest_framework',
'Orders',
]
ASGI_APPLICATION = "BrokerBackEnd.asgi.application"
Also, make sure daphne is actually installed:
pip install -U channels["daphne"]

Why swagger documentation doesn't work on PythonAnywhere domain?

I have used swagger to document my APIs on the Django rest framework, and deploy it on Pythonanywhere.
but the documentation URL doesn't have any response.
it is my urls.py code for swagger:
from drf_yasg.views import get_schema_view
from drf_yasg import openapi
schema_view = get_schema_view(
openapi.Info(
title="BoardGame API",
default_version='v1',
description="Test description",
terms_of_service="http://****.pythonanywhere.com/",
contact=openapi.Contact(email="contact#boardgame.local"),
license=openapi.License(name="TEST License"),
),
public=True,
permission_classes=(permissions.AllowAny,),
)
urlpatterns = [
...
path('', schema_view.with_ui('swagger', cache_timeout=0), name='schema-swagger-ui'),
]
and my settings.py
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'rest_framework',
'drf_yasg',
'rest_framework_swagger',
'rest_framework_simplejwt',
'django_extensions',
...
]

Its because your static files has not been loaded on server try to collectstatic files and check in inspect of page whether css is loading or not

You have to learn about static in Django
When you apply it all UI related files will be created in a static folder
Then swagger UI will work on pythonanywhere

It's seems that static file is not loaded on live server:
step 1:
LOCAL= False
step 2:
python manage.py collectstatic
step 3:
Reset server
nginx: sudo systemctl restart nginx
gunicorn: sudo systemctl restart gunicorn

How do I allow my django website to be hosted by a local server (127.0.0.1) and a Heruko server

I don't know if I am explaining my problem correctly but I can clarify with the following picture of my settings.py file
import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
# SECURITY WARNING: don't run with debug turned on in production!
# DEBUG = True
DEBUG = False
# ALLOWED_HOSTS = []
ALLOWED_HOSTS = ['sheryar-portfolio.herokuapp.com', '127.0.0.1']
# Application definition
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'pages',
'calculator',
'amino'
]
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',
]
Now here in ALLOWED_HOSTS, I have declared two hosts.
The Heroku one is running perfectly whereas I am having some issues in the local one.
It seems like that my static folder is not being located by django as I can only see the HTML of my website in local server.
In short, I cannot see the CSS being applied to my website when I am including the local server in ALLOWED_HOST

manage.py runserver fails after putting custom app in middleware

Im following a guide on youtube to work with django. Unfortunately this guide is made for pre 2.0 django.
So the challenge is to create a app called "posts" that can be accessed by localhost/posts.
After creating the folder 'posts' and adding it to settings.py MIDDLEWARE like this:
MIDDLEWARE = [
'posts',
'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',
]
python manage.py runserver fails
When commenting 'posts' out runserver succedes.
The problem is that Im so new to all of this that I don't even know what to search for.

try adding 'post' in INSTALLED_APPS inside settings.py like this:
INSTALLED_APPS = [
'post',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]
and delete it from middleware.
You have to "install" all the apps you make

Django - Authentication using REMOTE_USER - How to test in dev server?

I want to use django.contrib.auth.middleware.RemoteUserMiddleware for authentication as outlined here:
https://docs.djangoproject.com/en/dev/howto/auth-remote-user/
Question is, how can I test this in a dev environment where there is no Apache? i.e. can I set REMOTE_USER somehow in local settings?
EDIT (adding settings)
AUTHENTICATION_BACKENDS = (
'django.contrib.auth.backends.RemoteUserBackend',
)
MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.middleware.RemoteUserMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
)
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
...
)
Then I have this in my local_Settings:
os.environ['REMOTE_USER'] = "mmatyas"
I also tried the 'HTTP_REMOTE_USER' variant. Thanks!

The variable has to be set in the environment in which you start the dev server. usually it's just:
REMOTE_USER=myuser ./manage.py runserver

You can write some WSGI middleware and set it there, and then make sure the wsgi middleware wraps your django app in the wsgi stack. lots of tutorials around on writing wsgi middleware, it'll be a short one page of code. Easy-peasy-lemon-squeezy!

In your dev environment, you can set an environment variable in the same command prompt you use to start up your dev server.
Something like export REMOTE_USER="duncan" if on a Unixy machine.
You can also do this by editing your manage.py and setting os.environ['REMOTE_USER'] = "duncan"
