polymorphic association for element, anything else needs to be added?
===

I have adopted and I'm not sure exactly why something isn't working.

I have a pricable polymorphic association which I use for only a single model called Item. It looks like this:

    class Item < ActiveRecord::Base
      #price
      has_one :price, :as => :pricable
      accepts_nested_attributes_for :price
    
      attr_accessible :price_attributes, :price, ....


I'd like to add to an Event model and have added the following:

    class Event < ActiveRecord::Base
      #price
      has_one :price, :as => :pricable
      accepts_nested_attributes_for :price
      attr_accessible :price, :price_attributes

However, I am not able to set it:

    ruby-1.9.2-p290 :001 > e=Event.find(19) #ok
    ruby-1.9.2-p290 :002 > e.price
    Creating scope :page. Overwriting existing method Price.page.
      Price Load (0.8ms)  SELECT `prices`.* FROM `prices` WHERE `prices`.`pricable_id` = 19 AND `prices`.`pricable_type` = 'Event' LIMIT 1
     => nil 
    ruby-1.9.2-p290 :003 > e.price.price=23
    NoMethodError: undefined method `price=' for nil:NilClass
    	from /Users/jt/.rvm/gems/ruby-1.9.2-p290/gems/activesupport-3.1.0/lib/active_support/whiny_nil.rb:48:in `method_missing'
    	from (irb):3

Hmmm.... it looks like the relationship is set up correctly and that Event has access to price via attr_accessible. Any idea what else could be going on?

thx
