This method is used to access Ramaze::Cache.cache_helper_value. It provides an easy way to cache long-running computations, gathering external resources like RSS feeds or DB queries that are the same for every user of an application. This method changes behaviour if a block is passed, which can be used to do lazy computation of the cached value conveniently when using a custom TTL or longer expressions that don‘t fit on one line with ||=.
@example to get the cache object directly
count = cache_value[:count] ||= Article.count
@example with block
count = cache_value(:count){ Article.count } count = cache_value(:count, :ttl => 60){ Article.count }
@return [Object] The cache wrapper assigned for :cache_helper_value @see Innate::Cache @author manveru
