django-storages 1.11.1

Support for many storage backends in Django

Installation

Installing from PyPI is as easy as doing:

pip install django-storages

If you’d prefer to install from source (maybe there is a bugfix in master that hasn’t been released yet) then the magic incantation you are looking for is:

pip install -e 'git+https://github.com/jschneier/django-storages.git#egg=django-storages'

Once that is done set DEFAULT_FILE_STORAGE to the backend of your choice. If, for example, you want to use the boto3 backend you would set:

DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'

If you are using the FileSystemStorage as your storage management class in your models FileField fields, remove them and don’t specify any storage parameter. That way, the DEFAULT_FILE_STORAGE class will be used by default in your field. For example, if you have a photo field defined as:

photo = models.FileField(
    storage=FileSystemStorage(location=settings.MEDIA_ROOT),
    upload_to='photos',
)

Set it to just:

photo = models.FileField(
    upload_to='photos',
)

There are also a number of settings available to control how each storage backend functions, please consult the documentation for a comprehensive list.

About

django-storages is a project to provide a variety of storage backends in a single library.

This library is usually compatible with the currently supported versions of Django. Check the Trove classifiers in setup.py to be sure.

django-storages is backed in part by Tidelift. Check them out for all of your enterprise open source software commerical support needs.

Security

To report a security vulnerability, please use the Tidelift security contact. Tidelift will coordinate the fix and disclosure. Please do not post a public issue on the tracker.

History

This repo began as a fork of the original library under the package name of django-storages-redux and became the official successor (releasing under django-storages on PyPI) in February of 2016.

Found a Bug? Something Unsupported?

I suspect that a few of the storage engines in backends/ have been unsupported for quite a long time. I personally only really need the S3Storage backend but welcome bug reports (and especially) patches and tests for some of the other backends.

Issues are tracked via GitHub issues at the project issue page.

Documentation for django-storages is located at https://django-storages.readthedocs.io/.

1.7 (2018-09-03)

Security

• The S3BotoStorage and S3Boto3Storage backends have an insecure default ACL of public-read. It is recommended that all current users audit their bucket permissions. Support has been added for setting AWS_DEFAULT_ACL = None and AWS_BUCKET_ACL = None which causes all created files to inherit the bucket’s ACL (and created buckets to inherit the Amazon account’s default ACL). This will become the default in version 1.10 (for S3Boto3Storage only since S3BotoStorage will be removed in version 1.9, see below). Additionally, a warning is now raised if AWS_DEFAULT_ACL or AWS_BUCKET_ACL is not explicitly set. (#381, #535, #579)

Breaking

• The AzureStorage backend and documentation has been completely rewritten. It now depends on azure and azure-storage-blob and is vastly improved. Big thanks to @nitely and all other contributors along the way (#565)
• The .url() method of GoogleCloudStorage has been completely reworked. Many use cases should require no changes and will experience a massive speedup. The .url() method no longer hits the network for public urls and generates signed urls (with a default of 1-day expiration, configurable via GS_EXPIRATION) for non-public buckets. Check out the docs for more information. (#570)
• Various backends will now raise ImproperlyConfigured at runtime if their location (GS_LOCATION, AWS_LOCATION) begins with a leading / rather than silently stripping it. Verify yours does not. (#520)
• The long deprecated GSBotoStorage backend is removed. (#518)

Deprecation

• The insecure default of public-read for AWS_DEFAULT_ACL and AWS_BUCKET_ACL in S3Boto3Storage will change to inherit the bucket’s setting in version 1.10 (#579)
• The legacy S3BotoBackend is deprecated and will be removed in version 1.9. It is strongly recommended to move to the S3Boto3Storage backend for performance, stability and bugfix reasons. See the boto migration docs for step-by-step guidelines. (#578, #584)
• The long aliased arguments to S3Boto3Storage of acl and bucket are deprecated in favor of bucket_name and default_acl (#516)
• The minimum required version of boto3 will be increasing to 1.4.4 in the next major version of django-storages. (#583)

Features

• Add support for a file to inherit its bucket’s ACL by setting AWS_DEFAULT_ACL = None (#535)
• Add GS_CACHE_CONTROL setting for GoogleCloudStorage backend (#411, #505)
• Add documentation around using django-storages with Digital Ocean Spaces (#521)
• Add support for Django 2.1 and Python 3.7 (#530)
• Make S3Boto3Storage pickleable (#551)
• Add automatic reconnection to SFTPStorage (#563, #564)
• Unconditionally set the security token in the boto backends (b13efd)
• Improve efficiency of .listdir on S3Boto3Storage (#352)
• Add AWS_S3_VERIFY to support custom certificates and disabling certificate verification to S3Boto3Storage (#486, #580)
• Add AWS_S3_PROXIES setting to S3Boto3Storage (#583)
• Add a snazzy new logo. Big thanks to @reallinfo

• Fix SFTPStorageFile to align with the core File abstraction (#487, #568)
• Catch IOError in SFTPStorage.delete (#568)
• AzureStorage, GoogleCloudStorage, S3Boto3Storage and S3BotoStorage now respect max_length when file_overwrite = True (#513, #554)
