验证多态关联

Question

我有一个多态地址模型，我用了几种形式。我在那个模型中做了简单的验证，但它不起作用。我究竟做错了什么？

地址型号

class Address < ActiveRecord::Base 
    attr_accessible :street1, :street2, :city, state, :zip 
    belongs_to :addressable, :polymorphic => true 

    validates_length_of :state, :maximun => 2, :too_long => "Field State is to long" 

    validates_numericality_of :zip, :on => :create, :message => "Zip Code must be numeric!" 
    validates_length_of :zip, :within => 5..9, :too_long => "Zip Code to long.", :too_short => "Zip Code to short" 
end 

Location Model 

class Location < ActiveRecord::Base 
    has_one :address, :as => :addressable, :dependent => :destroy 
    belongs_to :account 

    accepts_nested_attributes_for :address 

    validates_presence_of :name 
    validates_length_of :name, :maximum =>80 
end 

位置编辑表单 - 例如

<% form_for [@account, @location] do |f| %> 
    <table> 
     <%= render :partial => 'form', :locals => {:f => f} %> 
    </table> 
    <%= f.submit("Update") %> 
<% end %> 

感谢您的帮助。 Ed

什么是错误？什么验证没有运行？ 另外，你可以看看： http://api.rubyonrails.org/classes/ActiveRecord/Validations/ClassMethods.html#method-i-validates_associated
