Caching doesn't seem to work correctly

Hey 👋🏼

First off, this is a great gem! I have enjoyed working with it.

I started caching my serializer using the cached macro. As I understand from the documentation, that would use the cache_key on the resource.

It does cache the first time I serialize the resource. Then I updated the resource and serialized it again. The second serialization uses the cached JSON, even though the resource has been updated.

Thanks,
Emil

Caching uses "cache_key" by default and not "cache_key_with_version" that includes the updated_at hash. That is why it behaves like this.
Example to solve this :

class VoteSerializer < Oj::Serializer
  cached_with_key ->(object) { object.cache_key_with_version }
  attributes :id, :voteable_id, :voteable_type, :user_id
  belongs_to :author
end
