I followed every QA suggestions found on SO and in different blogs, Everything works ok on my dev machine and nothing works on heroku.
here are my settings:
DEFAULT_FILE_STORAGE = 'arena.utils.MediaRootS3BotoStorage' # media files
# storage
AWS_ACCESS_KEY_ID = os.environ.get('AWS_ACCESS_KEY_ID')
AWS_SECRET_ACCESS_KEY = os.environ.get('AWS_SECRET_ACCESS_KEY')
AWS_STORAGE_BUCKET_NAME = os.environ.get('AWS_STORAGE_BUCKET_NAME')
AWS_PRELOAD_METADATA = True # necessary to fix manage.py collectstatic command to only upload changed files instead of all files
S3_URL = 'https://%s.s3.amazonaws.com' % AWS_STORAGE_BUCKET_NAME
MEDIA_URL = S3_URL + '/media/'
STATIC_URL = S3_URL + '/static/'
ADMIN_MEDIA_PREFIX = STATIC_URL + 'admin/'
COMPRESS_URL = STATIC_URL
COMPRESS_OFFLINE = True
COMPRESS_STORAGE = 'utils.CachedS3BotoStorage'
STATICFILES_STORAGE = COMPRESS_STORAGE
When i run collectstatic/compress everything is ok, i see the files being collected to S3 and put in proper places. I see the manifest file.
Loading any page with compressor tag, show an error OfflineGenerationError: You have offline compression enabled but key "d2a53169c44dec41ce3ee7da19b2b9d4" is missing from offline manifest.
Running python manage.py compress
again solves nothing. when i check the manifest file, indeed the key it looks for doesn't exist.
What is going wrong here?
Question i already checked:
How to configure django-compressor and django-staticfiles with Amazon's S3?
Django Compressor with S3 URL Heroku
Configuring django-compressor with remote storage (django-storage - amazon s3)
I found a git repository that contains post_compile hooks to solve this problem. It runs compress after Heroku built the Django app (and also installs
lessc
if you need less in your compressor settings).https://github.com/nigma/heroku-django-cookbook
