Hello.

Checking out your gem and it looks pretty good.

However I was wondering how would you go about comparing associations. Here is an example.

class Client
  has_many :addresses,  :as => :addressable,  :dependent => :destroy
  has_many :orders 
  validates_associated :addresses
  validates_associated :orders 
end

 class Address
   belongs_to :addressable, :polymorphic => true
 end

class Discount
  belongs_to :client
end

So consider these two cases:

Cient might have multiple addresses (shipping, billing, work, etc.), also if we introduce Warehouse model, it will need Addresses to - hence polymorphic association. So let's say I want to update a Client record. And the only thing that changed wasn't the actual client record, but the associated address ( let's say the zip code was wrong and I want to change that). How would I go about comparing for that?

Case 2
Let's say each client can have 2 types of discounts: Personal & Corporate . I want to add a new discount to a client, but before I save it I need to make sure one doesn't exist already and if it does maybe all i need is just change the discount rate, instead of creating a new discount.
