Question

我有一个多态地址模型，我用几种形式。我在该模型中进行简单验证，但它不起作用。我做错了什么？

地址模型

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。编

错误是什么？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
