Instance Method Details

#clean_cached_files!(seconds = 60*60*24) ⇒ Object

Removes cached files which are older than one day. You could call this method from a rake task to clean out old cached files.

You can call this method directly on the module like this:

CarrierWave.clean_cached_files!

Note

This only works as long as you haven’t done anything funky with your cache_dir. It’s recommended that you keep cache files in one place only.
