AR::Relation#cache_key
#5731
Provides a unique cache_key for ActiveRecord::Relation. Particularly useful when caching result sets or views:
@results = Person.babies
cache @results.cache_key do
...expensive stuff...
end

Robert PankoweckiNice, however undocumented.

laserlemonIt seems like custom cache keys and custom expiration are better suited for these types of situations. A relation's cache key doesn't communicate anything about its expiration. So if another baby were added to the people table, the cache key would remain. I'd just as soon do:
@results = Person.babies cache 'people/babies' do # Expensive stuff endif I have to expire the cache myself anyway.

I agree with, erm, laserlemon. Marking this wont fix for now (even though it's not really my decision). Will reopen if this develops further.
