Is it possible to use django_compressor/S3/gzip?

Question

How is it possible to use django_compressor to send gziped files to Amazon S3?

I tried in several ways but it didn\'t work. Here is my last settings.py configuration

Answer 1

Update 2019: it's described in the official documentation

#mysite.py
from django.core.files.storage import get_storage_class
from storages.backends.s3boto import S3BotoStorage

class CachedS3BotoStorage(S3BotoStorage):
    """
    S3 storage backend that saves the files locally, too.
    """
    def __init__(self, *args, **kwargs):
        super(CachedS3BotoStorage, self).__init__(*args, **kwargs)
        self.local_storage = get_storage_class(
            "compressor.storage.CompressorFileStorage")()

    def save(self, name, content):
        self.local_storage._save(name, content)
        super(CachedS3BotoStorage, self).save(name, self.local_storage._open(name))
        return name

And your settings:

#settings.py
INSTALLED_APPS += ['compressor']

AWS_IS_GZIPPED = True

STATIC_ROOT = '/path/to/staticfiles' #if not set, set this to an empty folder
COMPRESS_ROOT = STATIC_ROOT
STATICFILES_STORAGE = 'mysite.storage.CachedS3BotoStorage'
COMPRESS_STORAGE = STATICFILES_STORAGE
STATIC_URL = 'https://compressor-test.s3.amazonaws.com/'
COMPRESS_URL = STATIC_URL

Than you can simply run:

python manage.py collectstatic
