Use Backblaze as Django Default Storage

I want to use Backblaze to serve media files only in Django. I have used django-storages for that purpose, and as per it’s documentation it support Backblaze.

I used the below configuration in settings.py -

INSTALLED_APPS = [
    ............
    'storages',
    'boto',
]

STORAGES = {
    "default": {
        "BACKEND": "storages.backends.s3boto3.S3Boto3Storage",
    },
    "staticfiles": {
        "BACKEND": "whitenoise.storage.CompressedManifestStaticFilesStorage",
    },
}

AWS_ACCESS_KEY_ID = "<my_backblaze_application_keyID>"
AWS_SECRET_ACCESS_KEY = "<my_backblaze_applicationKey>"
AWS_STORAGE_BUCKET_NAME = "<my_public_bucket_name>"
AWS_S3_REGION_NAME = "<region_set_by_backblaze>"
AWS_S3_ENDPOINT = f"s3.{AWS_S3_REGION_NAME}.backblazeb2.com"
AWS_S3_ENDPOINT_URL = f"https://{AWS_S3_ENDPOINT}"
AWS_S3_CUSTOM_DOMAIN = f'{AWS_STORAGE_BUCKET_NAME}.{AWS_S3_ENDPOINT}'

MEDIA_URL = '/media/'

But the files are not uploading in the Backblaze. How to implement that properly?

As mentioned in Amazon S3 — django-storages 1.13.2 documentation, are you running collectstatic?
