Django S3 Storage Configuration Issue

The error you're encountering is due to an incorrect path to the S3 storage backend. With django-storages 1.14.4, the correct import path for the S3 backend has changed from what you're using.

Solution

The correct configuration for django-storages with S3 should be:

PYTHONCopied
STORAGES = {
    "staticfiles": {"BACKEND": "storages.backends.s3boto3.S3Boto3Storage"},
}

The key issue is that you're using storages.backends.s3.S3Storage, but the correct path is storages.backends.s3boto3.S3Boto3Storage.

Additional Configuration

You'll also need to configure AWS credentials and S3 bucket settings. Here's a typical configuration:

PYTHONCopied
# AWS Settings
AWS_ACCESS_KEY_ID = 'your-access-key'
AWS_SECRET_ACCESS_KEY = 'your-secret-key'
AWS_STORAGE_BUCKET_NAME = 'your-bucket-name'
AWS_S3_REGION_NAME = 'your-region'  # e.g., 'us-east-1'
AWS_S3_CUSTOM_DOMAIN = f'{AWS_STORAGE_BUCKET_NAME}.s3.amazonaws.com'
AWS_DEFAULT_ACL = 'public-read'  # or None to use bucket defaults
AWS_S3_OBJECT_PARAMETERS = {
    'CacheControl': 'max-age=86400',
}

Make sure you have 'storages' in your INSTALLED_APPS:

PYTHONCopied
INSTALLED_APPS = [
    # ...
    'storages',
    # ...
]

After making these changes, run python manage.py collectstatic to upload your static files to S3.
