./manage.py shell_plus --notebook failing with "AttributeError: 'PosixPath' object has no attribute 'startswith'"

[patrickhoebeke]

Hello,

I have some troubles using the command
./manage.py shell_plus --notebook

Its seems there are some incompatibility issues but I could not figure the root cause. Is this a bug ?

./manage.py shell_plus --notebook

I found the root cause thanks to this post:
https://groups.google.com/g/django-users/c/nrLxVflwTjY/m/MZEm4fc1BAAJ

Apparently, in the settings.py, you should not use something like:
BASE_DIR / 'someothervalue'
but rather
os.path.join(BASE_DIR, "someothervalue")

So, I am not sure wheter django-extension is concerned by this issue.
I leave to the experts the decision to close this issue ;-)
