.revalidate_tag(tag) ⇒ Integer

Deletes every cached component entry registered under tag (written via the cache_tags: option on the cached_* helpers) and clears the tag's index entry. A missing/never-written tag is a no-op. Returns the number of cache entries deleted.

Revalidation is best-effort: the tag index is itself stored in Rails.cache and its appends are lossy under concurrency, so correctness is bounded by the :expires_in of the tagged entries. See docs/pro/fragment-caching.md.

Parameters:

  • tag (Object)

Returns:

  • (Integer)

end

.revalidate_tags(*tags) ⇒ Integer

Splat form of revalidate_tag. Tags accept the same forms as the cache_tags: option (String, object responding to #cache_key such as an ActiveRecord model, Proc, or Array of any mix). Returns the total number of cache entries deleted.

Parameters:

  • tags (Object)

Returns:

  • (Integer)
