Django pipeline Cache Busting is not Updating Cached File/Hash
Try using the manifest storage instead:
class S3PipelineManifestStorage(PipelineMixin, ManifestFilesMixin, S3BotoStorage): passAccording to the django docs here https://docs.djangoproject.com/en/1.11/ref/contrib/staticfiles/#cachedstaticfilesstorage it's not recommended to use CachedStaticFilesStorage.
Your files names for your static files are probably getting cached. So use the manifest one.
CachedStaticFilesStorage isn’t recommended – in almost all cases ManifestStaticFilesStorage is a better choice. There are several performance penalties when using CachedStaticFilesStorage since a cache miss requires hashing files at runtime. Remote file storage require several round-trips to hash a file on a cache miss, as several file accesses are required to ensure that the file hash is correct in the case of nested file paths.
