Offline compressing files from 3rd party app

[jrief]

I have a third party app which is shipped with their own scss files. During development I'd like to use django-libsass, but CSS files shall be delivered precompiled for easier deployment. Otherwise each customer would have to install libsass, which requires a C++ compiler on the production host.

Since this third party app can not run by itself, I added a manage.py script together with a minimal settings.py. Beside the usual boilerplate, this file essentially contains the following settings:

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.staticfiles',
    'compressor',
    'my_app',
)

COMPRESS_ROOT = os.path.join(PROJECT_DIR, 'my_app/static')

STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    'compressor.finders.CompressorFinder',
)

COMPRESS_PRECOMPILERS = (
    ('text/x-scss', 'django_libsass.SassCompiler'),
)

COMPRESS_OFFLINE = True

With ./manage compress I'm able to convert all my scss files into css. These files then are stored below my_app/static/CACHE/css/... together with a manifest.json.

Adding

{% compress css %}<link rel="stylesheet" type="text/x-scss" href="{% static 'my_app/css/foo.scss' %}" />{% endcompress %}

to a Django template works perfectly during development: my_app/css/foo.scss is converted on the fly into a css file. But during production, I have to access the files prebuilt with ./manage compress.

Unfortunately I did not find out how to access these precompiled files on a production host. If I remove the COMPRESS_PRECOMPILERS (which is the prerequisite explained above), then the browser accesses the scss files directly, but of course that's not what I want.

And from the docs I haven't found out how to configure an app to access the precompiled files.
Any hints?
