What's the proper way to override Rails ActiveRecord creation/deletion events in a subclass, such as after_create

Question

Hi, I have a class heirarchy as follows:

class A < ActiveRecord::Base
  after_create { |i|
    #do something
  }
end

class B < A
  after_create { |i|
    #do something else after what A did
  }
end

I want to have A's behavior performed in B when after_create is invoked, but I am not sure of the proper way to write the after_create method in B.

Answer 1

You can call the superclass version of a method using "super," like this:

class B < A
  def after_create
    super
    #now do something else after what A did
  end
end

Answer 2

Each callback you define will be called, in order. You don't have anything special to do to get the behavior you want. The syntax you used is the correct one.
