from S3 import CallingFormat, seems broke
From the docs it says ...
The way you’d like to call the Amazon Web Services API, for instance if you prefer subdomains:
from S3 import CallingFormat AWS_CALLING_FORMAT = CallingFormat.SUBDOMAIN
However django-storages doesn't seem to install the S3 library ...
>>> from S3 import CallingFormat Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named S3
I think the docs should include instructions on how to install it or setup.py should be modified to install it.
