I'm new to Django and this is a first time I'm trying to deploy my Django application on WebFaction. I searched on StackOverflow but did not find someone who encountered the same problem.
My app was developed using Django 2.2 and Python 3.7.3. I have run successfully makemigrations, migrate, collectstatic on my computer's localhost and run successfully those commands when using PuTTY on Windows getting SSH to WebFaction server.
However when I restart the WebFaction server and access using browser, it returned ModuleNotFoundError.
ModuleNotFoundError at /
No module named 'app_www_admission.urls'
Request Method: GET
Request URL: (my website's URL)
Django Version: 2.1.7
Exception Type: ModuleNotFoundError
Exception Value:
No module named 'app_www_admission.urls'
Exception Location: <frozen importlib._bootstrap> in _find_and_load_unlocked, line 965
Python Executable: /usr/local/bin/python3
Python Version: 3.7.3
Python Path:

I tried resolving the package that I imported in these files: admin.py, forms.py, models.py, settings.py, main urls.py, the app's urls.py, views.py and I realized that:
For development, I must import using:
from app_www_admission.models import ...For production, when I restart the Webfaction server, I must import using:
from app_www_admission.app_www_admission.models import ...
The option (1) lets me run the makemigrations, migrate, collectstatic, check, etc on commands but resulted ModuleNotFoundError when visiting the website by browser as I mentioned above. The error log by the server is attached below.
The option (2) lets me visit the website by browser as I expected (no more ModuleNotFoundError in the browser) but I can't do anything with commands makemigrations, migrate, collectstatic, check, etc because it always throws
ModuleNotFoundError: No module named 'app_www_admission.app_www_admission'.
For more information, I deployed by copying all files from local computer to the WebFaction, installed pip, and neccessary packages but it seems that the problem is with the app_www_admission. Now what I can do is: switch to (1), run all my necessary commands (to migrate or something), then switch to (2) by editting all related files on server, then restart server. Switching between these options is very stressful and I knew I must be silly and wrong somewhere.
Could you please tell me what was wrong with the import paths that I mentioned or what was wrong with the settings or something? I really appreciate all your help.
