combined_fragment_cache_key(key) public

Given a key (as described in expire_fragment), returns a key array suitable for use in reading, writing, or expiring a cached fragment. All keys begin with :views, followed by ENV[“RAILS_CACHE_ID”] or ENV[“RAILS_APP_VERSION”] if set, followed by any controller-wide key prefix values, ending with the specified key value.
