class Address \< ActiveRecord::Base  
belongs\_to :addressable, :polymorphic =\> true  
end

class Client \< ActiveRecord::Base  
has\_one :address, :as =\> :addressable  
end

Now I’am able to create a correct entry in the db for address with  
addressable\_id = 1#client\_id  
addreassable\_type = ‘Client’

but when I retrieve  
client = Client.find(1) --\> return client instance with id =1  
address = client.address -\> address is not nil

BUT  
address.attributes == nil

Somehow I can’t retrieve the address back using association  
client.address even though I could create it.  
I must be missing something simple. Would appreciate any tips.
