Question

Answer 1

If you're doing fragment caching, you can manually break the cache by updating your cache key, like so:

Version #1

<% cache ['cool_name_for_cache_key', 'v1'] do %>

Version #2

<% cache ['cool_name_for_cache_key', 'v2'] do %>

Or you can have the cache automatically reset based on the state of a non-static object, such as an ActiveRecord object, like so:

<% cache @user_object do %>

With this ^ method, any time the user object is updated, the cache will automatically be reset.
