I run the following line of code on a Docker container:
RUN python3 manage.py sitetree_resync_apps --settings=sites.production.settings
and I get the following error:

I located the error on the manage.py file:
#!/usr/bin/env python
import os
import sys
if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "xxx.settings")
from django.core.management import execute_from_command_line
execute_from_command_line(sys.argv)
If I comment out the offending line in the Dockerfile the container successfully build but when I try to hop into it with the code:
docker-compose up -d && docker-compose logs -f
I get the error:
nettle_1 | Traceback (most recent call last):
nettle_1 | File "manage.py", line 8, in <module>
nettle_1 | from django.core.management import execute_from_command_line
nettle_1 | ImportError: No module named django.core.management
exited with code 1
I am completely lost here.
EDITED Hi Melvin, this is my app.py
from mcvitty.site.signals import resource_event, notify_by_email
from django.apps import AppConfig
class InvoicingConfig(AppConfig):
name = 'mcvitty.invoicing'
verbose_name = "Invoices"
def ready(self):
resource_event.connect(notify_by_email, sender='invoicing.Invoice')
Due to my lack of experience with django I still fails to understand the error and how to set app.py correctly
Your problem is here:
File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
File "/xxx/xxx/invoicing/apps.py", line 10, in <module>
from xxx.site.signals import resource_event, notify_by_email
File "/xxx/xxx/site/signals.py", line 12, in <module>
from xxx.backend.email import send_email
File "/xxx/xxx/backend/email.py", line 11, in <module>
from post_office import mail
Your invoicing apps imports signals that import models from post_office. You should only register signals when all apps are loaded, through AppConfig.ready() as is explained in the documentation:
Subclasses can override this method to perform initialization tasks such as registering signals. It is called as soon as the registry is fully populated.
For clarity: this includes importing utilities / modules that import models from other apps as that lies at the core of the problem.
