def cache_ttl
  @cache_ttl.equal?(NEVER_ASSIGNED) ? self.class.defaults[:cache_ttl] : @cache_ttl
end

#cache_ttl=(value) ⇒ Object

A non-positive number folds into nil too -- a TTL of zero or less can never keep a row. Coerced here, then handed to super so the declared writer's cache_store invalidation still runs.
