django-s3-storage 0.9.4

Django Amazon S3 file storage.

Latest Version: 0.11.3

django-s3-storage provides a Django Amazon S3 file storage.

Features

  • Django file storage for Amazon S3.
  • Django static file storage for Amazon S3.
  • Works in Python 3!

Installation

  1. Install using pip install django-s3-storage.
  2. Add 'django_s3_storage' to your INSTALLED_APPS setting.
  3. Set your DEFAULT_FILE_STORAGE setting to "django_s3_storage.storage.S3Storage".
  4. Set your STATICFILES_STORAGE setting to "django_s3_storage.storage.StaticS3Storage" or "django_s3_storage.storage.ManifestStaticS3Storage".
  5. Configure your Amazon S3 settings (see Available settings, below).

Available settings

# The region to connect to when storing files.
AWS_REGION = "us-east-1"

# The AWS access key used to access the storage buckets.
AWS_ACCESS_KEY_ID = ""

# The AWS secret access key used to access the storage buckets.
AWS_SECRET_ACCESS_KEY = ""

# The S3 bucket used to store uploaded files.
AWS_S3_BUCKET_NAME = ""

# A prefix to add to the start of all uploaded files.
AWS_S3_KEY_PREFIX = ""

# Whether to enable querystring authentication for uploaded files.
AWS_S3_BUCKET_AUTH = True

# The expire time used to access uploaded files.
AWS_S3_MAX_AGE_SECONDS = 60*60  # 1 hour.

# The S3 bucket used to store static files.
AWS_S3_BUCKET_NAME_STATIC = ""

# Whether to enable querystring authentication for static files.
AWS_S3_BUCKET_AUTH_STATIC = False

# A prefix to add to the start of all static files.
AWS_S3_KEY_PREFIX_STATIC = ""

# The expire time used to access static files.
AWS_S3_MAX_AGE_SECONDS_STATIC = 60*60*24*365  # 1 year.

Important: If you change any of the AWS_S3_BUCKET_AUTH or AWS_S3_MAX_AGE_SECONDS settings, you will need to run ./manage.py s3_sync_meta path.to.your.storage before the changes will be applied to existing media files.

How it works

By default, uploaded user files are stored on Amazon S3 using the private access control level. When a URL for the file is generated, querystring auth with a timeout of 1 hour is used to secure access to the file.

By default, static files are stored on Amazon S3 using the public access control level and aggressive caching.

Text-based files, such as HTML, XML and JSON, are stored using gzip to save space and improve download performance.

At the moment, files stored on S3 can only be opened in read-only mode.

Optimizing media file caching

The default settings assume that user-uploaded file are private. This means that they are only accessible via S3 authenticated URLs, which is bad for browser caching.

To make user-uploaded files public, and enable aggressive caching, make the following changes to your settings.py.

AWS_S3_BUCKET_AUTH = False

AWS_S3_MAX_AGE_SECONDS = 60*60*24*365  # 1 year.

Important: By making these changes, all user-uploaded files will be public. Ensure they do not contain confidential information.

Important: If you change any of the AWS_S3_BUCKET_AUTH or AWS_S3_MAX_AGE_SECONDS settings, you will need to run ./manage.py s3_sync_meta path.to.your.storage before the changes will be applied to existing media files.

Management commands

s3_sync_meta

Syncronizes the meta information on S3 files.

If you change any of the AWS_S3_BUCKET_AUTH or AWS_S3_MAX_AGE_SECONDS settings, you will need to run this command before the changes will be applied to existing media files.

Example usage: ./manage.py s3_sync_meta django.core.files.storage.default_storage
