instance method
expire_fragment
Ruby on Rails edge
Since v5.0.7.2Signature
expire_fragment(key, options = nil)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).
