I'm configuring my Django project to use S3 buckets to store static and media files, both for local and production settings.

My project tree is as follows:

   src/
      blog/
          settings/
                  __init__
                  local.py
                  production.py
          s3utils.py
          [..]
      [..]

My local.py:

access_key = "xx"
secret_key = "yy"

AWS_ACCESS_KEY_ID = access_key
AWS_SECRET_ACCESS_KEY = secret_key
AWS_STORAGE_BUCKET_NAME = 'zz'


STATICFILES_STORAGE = 'blog.s3utils.StaticRootS3BotoStorage'
DEFAULT_FILE_STORAGE = 'blog.s3utils.MediaRootS3BotoStorage'
S3DIRECT_REGION = 'us-west-2'
S3_URL = 'http://%s.s3.amazonaws.com/' % AWS_STORAGE_BUCKET_NAME
MEDIA_URL = 'http://%s.s3.amazonaws.com/media/' % AWS_STORAGE_BUCKET_NAME
MEDIA_ROOT = MEDIA_URL
STATIC_URL = S3_URL + "/static/"
ADMIN_MEDIA_PREFIX = STATIC_URL + 'admin/'

import datetime

two_months = datetime.timedelta(days=61)
date_two_months_later = datetime.date.today() + two_months
expires = date_two_months_later.strftime("%A, %d %B %Y 20:00:00 GMT")

AWS_HEADERS = { 
    'Expires': expires,
    'Cache-Control': 'max-age=%d' % (int(two_months.total_seconds()), ),
}

my s3utils.py:

from storages.backends.s3boto import S3BotoStorage

StaticRootS3BotoStorage = lambda: S3BotoStorage(location='static') 
MediaRootS3BotoStorage  = lambda: S3BotoStorage(location='media') 

When I run:

python manage.py collectstatic

only (django) admin static files are copied to my s3 bucket.

I thought that the problem was that I misconfigured the permission of my IAM user, but actually I do have the permissions to copy the 'admin/' files to the s3 bucket.

Thank you for any help you can provide.
