staticfiles.storage.StaticFilesStorage.post_process()

storage.StaticFilesStorage.post_process(paths, **options)

This method is called by the collectstatic management command after each run and gets passed the local storages and paths of found files as a dictionary, as well as the command line options.

The CachedStaticFilesStorage uses this behind the scenes to replace the paths with their hashed counterparts and update the cache appropriately.
