remote model callbacks - rails 3?
===

I'm not phrasing the question correctly in the title, but heres what I'd like to do.

I have a method, like such:

    class User < ActiveRecord::Base
       def myMethod(abc, xyz)
         #do stuff
       end
    end

I want 5 different models in my app to call this function on their after_create callback.

It seems very anti-DRY to put a function in each of those models to call this function.

Is there a way in this model (above) that holds the method - to remotely use the callbacks of the other models?

Or can anyone suggest a different way I should be approaching something like this?
