How do I flush a class method in Rails 4 using memcached?

I think the issue was by ths following , The problem is that you're using self.class.name in a class method and an instance method.
First, here's the solution, change self.cached_latest to:
code :
def self.cached_latest
  Rails.cache.fetch([name, 'latest']) { Update.all.limit(5) }
end
def self.cached_latest
  Rails.cache.fetch([name, 'latest', count, order(updated_at: :desc).first.updated_at]) { Update.all.limit(5) }
end
['Update', 'latest', 45, "date of latest record's updated_at timestamp"]

Any of those help If will also clear envCache if it's on the same memcached instance/server as configCache. Because memcached doesn't support namespaces only all keys can be removed from the instance.

I hope this helps . Memcached does not have support for range queries so unfortunately you cannot flush a subset of keys.
