Error customization problem.


I have following models

class User < ActiveRecord::Base has_many :addresses, :as =>:addressee, :dependent => :destroy accepts_nested_attributes_for :addresses, :allow_destroy => true end

class Address < ActiveRecord::Base

  belongs_to :addressee, :polymorphic => true

  validates_presence_of :address1, :maximum => 50,:message => "Address1 cannot be blank."   validates_presence_of :city,:message => "City cannot be blank."   validates_presence_of :state,:message => "State cannot be blank."   validates_presence_of :zipcode,:message => "Zip Code cannot be blank."   validates_presence_of :country,:message => "Country cannot be blank." end

also in my environment file(environment.rb)

  #Customize errors   config.action_view.field_error_proc = do |html_tag, instance|     if instance.error_message.kind_of?(Array)      %{<div class="input">#{html_tag}</div><div class="error">&bull;#{[instance.error_message].join('<br/>&bull;')}</div>}     else      %{<div class="input">#{html_tag}</div><div class="error">&bull;#{[instance.error_message].flatten.first}</div>}     end   end

when i am creating user it will give me all model validations error properly. but when i am updating user it only show user model validations. for addresses if any error is there or it is not showing that message inside my form. i am not understanding why this is happening? anybody can give me how can i debug this problem?   i have used field_error_proc for customizing my error messages(show error for field level)

  Please help me out what's going wrong?
