[Rails] I want to override ActiveModel#errors.as_json, but how?

[Lille]

Hey,

I want custom errors.as_json behavior from my implementation of
ActiveModel and with inheritance!

So how do I do something like shown in the following pseudo?

module A
   include ActiveModel

   def errors.to_json
      "blow"
   end
end

module B
    include A

   def errors.to_json
      "go " + super
   end
end


So far, I've been fooling around using instance_eval on errors in A,
but I can't get inheritance from that in B.
