I'm writing project using docker and django (2.1).
I've installed module 'django-widget-tweaks' inside a container and added 'widget_tweaks' to INSTALLED_APPS. When I start project using docker-compose up everything works well, but when I want to run something like docker-compose run <container name> python manage.py test in another terminal an error occurs.
Traceback (most recent call last):
File "manage.py", line 15, in <module>

ModuleNotFoundError: No module named 'widget_tweaks'
But when I directly run the same command python manage.py test inside a docker container, it works. widget-tweaks has been installed both on container and on my machine. Could you advice something to solve the problem?
Thanks in advance!

! Error while running '$ python pytorch_django/manage.py collectstatic --noinput'.
I have successfully deployed other Django apps on Heroku and I don't get what's wrong here. What does KeyError: 'collectstatic' mean or where does it come from?
Locally, the app runs fine and also python manage.py collectstatic runs fine. What's the problem? Could it be related to Python 3.9? I have Python 3.8 locally.
Edit: This also happens with a freshly created Django app - no changes in the code whatsover.
The problem was my own fault but not in the Django app but in my Heroku configuration.
Inside my Heroku environmental variables (Settings > Config Vars), I had set the DJANGO_SETTINGS_MODULE incorrectly to project.prod_settings.
However, my Django project was called pytorch_django so I had to set it to pytorch_django.prod_settings.
That's what caused the error ModuleNotFoundError: No module named 'project'.
Changing DJANGO_SETTINGS_MODULE to the correct path solved the problem.

ModuleNotFoundError: No module named 'responsive_images'
You have to make sure you add the library to your INSTALLED_APPS list in settings.py. It's useful to keep in mind the library name as it's downloaded is usually different than it's name in pip. for Example this is installed with pip install django-responsive-images, but responsive_images is what you should include in your INSTALLED_APPS.
I would like to use https for my Django development server using django-sslserver.
I have installed it using
$ pip install django-sslserver
I have then added it to my settings.py INSTALLED APPS:
INSTALLED_APPS = [
...
'sslserver',
...
]
However, if I now try to start the sslserver like this:
python3 manage.py runssslerver 0.0.0.0:8080
I get the following error:

ModuleNotFoundError: No module named 'sslserver'
Any idea how to fix this?
If you are using native python in linux, the pip and pip3 is different. You can try pip3 install django-sslserver.
I recommend to use virtual environment in web service development of python, e.g. pipenv.
I'm trying to run this command on my django project:

to create a new empty migration.

What am I doing wrong?
I'm on Windows 10 and I'm using VS2017 to developp my Django app.
EDIT:
Something very strange. When I run pip freeze, I get this:
$ pip freeze
astroid==1.4.9
colorama==0.3.7
Django==1.10.3
isort==4.2.5
lazy-object-proxy==1.2.2
mccabe==0.6.1
pylint==1.6.5
six==1.10.0
wrapt==1.10.10
I don't know what are thoses packages. I have no mention of astroid or mccabe in my whole project. Nor in site-package folder, nor in INSTALLED-APP...
I'm trying to get Django to work. I installed Django used
django-admin startproject mysite
This created this structure
mysite
-- manage.py
-- mysite
- __init__.py
- settings.py
- etc etc...
now I'm when I run
python manage.py runserver
I get this error

ModuleNotFoundError: No module named 'mysite'
Python cannot find 'mysite'
I've tried PYTHONPATH = 'my director' but so far nothing has worked. Problem seems to be that python cannot find mysite folder
Ok, I'm answering my own question again.
For some strange reason, Python is unable to find the app folder /mysite and even though I set
PYTHONPATH = C:\...\mysite
It did not work
I found a hack to include the directory by inserting this after
import sys
sys.path.append("C:\\xampp\\your\\path\\site1") <--- insert this line (3)
in manage.py, this forces python to look for your app folder when it runs the server. Put the double slashes as well.
