I'm trying to setup django-compressor and django-staticfiles so that the compressed CSS/Javascript and images are served from Amazon's S3.
I've managed to setup staticfiles using S3 as the backend so it's collectstatic
command sends the files to S3 instead of STATIC_ROOT
.
However when trying to add django-compressor
to the mix is where it all seems to fall apart for me. Following the documentation on setting up remote storages I've created a subclass of the storage backend, boto, so I copied the example to storage.py
. Once I start using this cached backend the files are copied into static_media and not S3. After the first page load the CACHE folder appears on S3 and in the static_media folder.
Setting STATICFILES_STORAGE
and COMPRESS_STORAGE
back to boto's normal S3 class (storages.backends.s3boto.S3BotoStorage
) results in the static assets being collected into the S3 bucket and no static_media folder. However trying to reload the page throws the error:
Caught NotImplementedError while rendering: This backend doesn't support absolute paths.
highlighting {% compress css %}
as the tag and compressor/base.py
as the origin.
The s3/staticfiles/compressor section of my settings.py
:
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
AWS_ACCESS_KEY_ID = 'key'
AWS_SECRET_ACCESS_KEY ='secret'
AWS_STORAGE_BUCKET_NAME = 'my-bucket'
S3_URL = 'http://my-bucket.s3.amazonaws.com/'
MEDIA_ROOT = 'client_media'
MEDIA_URL = '/media/'
STATIC_ROOT = 'static_media'
STATIC_URL = S3_URL
ADMIN_MEDIA_PREFIX = S3_URL + 'admin/'
STATICFILES_DIRS = (
join(DIRNAME, 'static'),
)
STATICFILES_FINDERS = (
'django.contrib.staticfiles.finders.FileSystemFinder',
'django.contrib.staticfiles.finders.AppDirectoriesFinder',
'compressor.finders.CompressorFinder',
)
COMPRESS_ENABLED = True
COMPRESS_URL = S3_URL
COMPRESS_ROOT = STATIC_ROOT
COMPRESS_STORAGE = 'storage.CachedS3BotoStorage'
STATICFILES_STORAGE = COMPRESS_STORAGE
So where am I going wrong? Have I mis-configured something when using the CachedS3BotoStorage
custom storage maybe?
Your settings look correct. You should keep both STATICFILES_STORAGE
and COMPRESS_STORAGE
set to storage.CachedS3BotoStorage
though and not switch back to storages.backends.s3boto.S3BotoStorage
.
According to this django-compressor issue, the problem is with the way django-staticfiles saves during the collectstatic process (using shutil.copy2
). This issue has been corrected in the newer version of django-staticfiles, which can be used instead of the one that ships with Django 1.3.
pip install django-staticfiles==dev
And in your settings.py
, switch to the updated version:
STATICFILES_FINDERS = (
#"django.contrib.staticfiles.finders.FileSystemFinder",
#"django.contrib.staticfiles.finders.AppDirectoriesFinder",
"staticfiles.finders.FileSystemFinder",
"staticfiles.finders.AppDirectoriesFinder",
"compressor.finders.CompressorFinder",
)
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
#'django.contrib.staticfiles',
'staticfiles',
#...
)
After running python manage.py collectstatic
again, both the CACHE directory from django-compressor and the collected staticfiles files should show up on S3.
