How can I use django-storages for both media and static files?

I'm attempting to use http://django-storages.readthedocs.org/en/latest/backends/amazon-S3.html for serving both static files and uploaded media, but I'm not certain it's possible. Is there a documented way that I'm missing? Also, I would assume (hope) that you could configure a separate bucket for each, but I can't find any info on that.

Solution

Yes this is possible by configuring both DEFAULT_FILE_STORAGE and STATICFILES_STORAGE to use the S3 storage. However if you set

DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
STATICFILES_STORAGE = 'storages.backends.s3boto.S3BotoStorage'

then these will both use the default settings for the S3 storage, meaning they will both use the AWS_STORAGE_BUCKET_NAME bucket. The way to work around this is to create a small subclass of S3BotoStorage in your project which uses a different setting for the bucket name.

from django.conf import settings

from storages.backends.s3boto import S3BotoStorage

class S3StaticStorage(S3BotoStorage):

    def __init__(self, *args, **kwargs):
        kwargs['bucket']  = settings.AWS_STATIC_BUCKET_NAME
        super(S3StaticStorage, self).__init__(*args, **kwargs)

You would then define the AWS_STATIC_BUCKET_NAME setting to be whatever you want for your static bucket and change AWS_STATIC_BUCKET_NAME to the path for this custom storage class.

STATICFILES_STORAGE = 'dotted.path.to.storage.S3StaticStorage'

If you wanted to change other settings such as AWS_QUERYSTRING_AUTH, AWS_S3_CUSTOM_DOMAIN, AWS_PRELOAD_METADATA, etc then you would change them in this subclass as well.
