Question

I cannot figure this out from what I have read on Google, but I want to make a gem that will alter the behavior of the module when it saves, but I don’t know how to do this. How would I define in the Gem a save method that overrides the model’s save method?

Update: I have found Rails 3: alias_method_chain still used?, which I will check into. It appears that alias_method_chain is deprecated for Rails 3.

I’d rather do this :

module YourModule

  def self.included(base)
    base.extend(InstanceMethods)
  end

  module InstanceMethods

    def save
      # Your behavior here
      super # Use this if you want to call the old save method
    end
  end
end

And then in the model :

class User < ActiveRecord::Base
  include YourModule
end

Hope it helps 🙂
