AbstractController::Caching::Fragments
expire_fragment(key, options = nil)public
Removes fragments from the cache.
`key` can take one of three forms:
-
String - This would normally take the form of a path, like `pages/45/notes`.
-
Hash - Treated as an implicit call to `url_for`, like `{ controller: ‘pages’, action: ‘notes’, id: 45}`
-
Regexp - Will remove any fragment that matches, so `%r{pages/d*/notes}` might remove all notes. Make sure you don’t use anchors in the regex (`^` or `$`) because the actual filename matched looks like `./cache/filename/path.cache`. Note: Regexp expiration is only supported on caches that can iterate over all keys (unlike memcached).
`options` is passed through to the cache store’s `delete` method (or `delete_matched`, for Regexp keys).
