未命名模块<app_name>

Question

So, I made a chat app using django-channels in a separate project and now I am copying it into the main project.

This is what is happening. when I run ./manage.py runserver

Unhandled exception in thread started by <function wrapper at 0x7f695c1cfde8>

    raise ImproperlyConfigured("Cannot import channel routing %r: %s" % (routing, e))
django.core.exceptions.ImproperlyConfigured: Cannot import channel routing 'website.routing.channel_routing': No module named myWebsite

I know this is some error with django not recognising my module , but in other places it's recognising so why not here

The culprit code, the reason why I am stuck here for 2 days :

website/website/routing.py

from channels import include
from myWebsite.routing import websocket_routing, custom_routing


channel_routing = [
    # Include sub-routing from an app.
    include(websocket_routing, path=r"^/chat/stream"),
    include(custom_routing),
]

website/myWebsite/routing.py

from channels import route
from .consumers import ws_connect, ws_receive, ws_disconnect, chat_join, chat_leave, chat_send


websocket_routing = [
    route("websocket.connect", ws_connect),

    route("websocket.receive", ws_receive),

    route("websocket.disconnect", ws_disconnect),
]


custom_routing = [
    # Handling different chat commands (websocket.receive is decoded and put
    # onto this channel) - routed on the "command" attribute of the decoded
    # message.
    route("chat.receive", chat_join, command="^join$"),
    route("chat.receive", chat_leave, command="^leave$"),
    route("chat.receive", chat_send, command="^send$"),
]

Later I added this in website/myWebsite/__init.py__ :

default_app_config='myWebsite.apps.MywebsiteConfig'

website/website/settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'myWebsite',
    'django_countries',
    'social_django',
    'channels',
]

ROOT_URLCONF = 'website.urls'

The directory structure :

website
├── __init__.py
├── manage.py
├── myWebsite
│   ├── admin.py
│   ├── apps.py
│   ├── backends.py
│   ├── constants.py
│   ├── consumers.py
│   ├── exceptions.py
│   ├── forms.py
│   ├── __init__.py
│   ├── media
│   ├── migrations
│   │   ├── 0001_initial.py
~~ SNIP ~~
│   ├── models.py
│   ├── routing.py
│   ├── settings.py
│   ├── signals.py
│   ├── static
 ~~ SNIP ~~
│   ├── templates
 ~~ SNIP ~~
│   ├── tests.py
│   ├── urls.py
│   ├── utils.py
│   └── views.py
└── website
    ├── config.py
    ├── __init__.py
    ├── routing.py
    ├── settings.py
    ├── urls.py
    ├── views.py
    └── wsgi.py

So as you can see well above I do have the __init__.py in website/myWebsite directory.

Any help would be greatly appreciated. It has stalled my work for the last 2 days as I have tried it all.

Thanks

Update As per comments

New website/website/routing.py

from channels import include
import sys
from myWebsite.routing import websocket_routing, custom_routing


print(sys.path)
channel_routing = [
    include(websocket_routing, path=r"^/chat/stream"),
    include(custom_routing),
]

website/website/settings.py

INSTALLED_APPS = [
    ~~ SNIP ~~
    'channels',
    'myWebsite',
    'django_countries',
    'social_django',
]

Since neither of it help so reverting to the original code

Answer 1

Why is there an __init__.py in the main directory? None of my Django projects do.

Unless my understanding of these things is wrong —which is entirely possible— that would be turning website into its own module. That would change the absolute path you're using in website/website/routing.py to website.myWebsite.routing . Yuck.

You could update the absolute path in the import, but honestly, I'd just nuke the file and not turn the active directory into a module.

Answer 2

There was an error in the utils.py file

I found this error when I used shell on my friend's recommendation.

It popped up when I executed this from myWebsite.routing import websocket_routing, custom_routing

and there was no error while just executing import myWebsite
