I have created a custom storage backend, the file is called storages.py and is placed in an app called core:
from django.conf impor
There is a namespace conflict; the storage absolute name clashes with a storage local name. It may be unintuitive, but you can import from module in itself:
// file my_module/clash.py
import clash
print clash.__file__
Now we run python shell in a dir containing a my_module:
$ python
>>> import my_module.clash
my_module.clash.py
In short, your module tries to import a backend from itself.
You need an absolute import - Trying to import module with the same name as a built-in module causes an import error.
I had this same issue, but for me it turns out that despite django-storages being installed, boto was not. A simple pip install boto fixed the error in my scenario.
I had another type of issue that can help others, I used to have another file named storages.py but I deleted that file days ago, and still getting the Exception... the thing is I didn't had deleted the file storages.pyc !
Typo error. Change:
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
TO:
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3Boto3Storage'
