Reproducible example for django-environ issue #497
git clone https://github.com/amstilp/django-environ-issue-497.git
cd django-environ-issue-497
python -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python manage.py shell
In the django shell:
from django.conf import settings
print(settings.SECRET_KEY)
The secret key should be test-#secret-key-with-a-hash-in-it, but in settings.SECRET_KEY it is truncated after the hash characfter to test-.
I've seen this on both python 3.8 and 3.9. I used python 3.9 for this repo/example.
