instance method `expire_fragment`

Ruby on Rails 5.2.8.1

Since v5.2.8.1

Available in: v5.2.8.1 v6.0.6 v6.1.7.10 v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

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).

Parameters

key req
options opt = nil
