Question

1. i have two models department and address and they are associated
   with one another but when i use client side form validation address
   model fields are not getting validated. The javascript for
   validating associated model is not being generated.

2. Department model

   class Department < ActiveRecord::Base   
       attr_accessible :agency_head, :agency_head_rank, :department_type_id, :fax, :name,
                       :phone, :address_attributes
       validates :name , :length => { :minimum => 2 } , :presence => true
       validates :department_type_id , :agency_head,:agency_head_rank,:phone,:fax, :presence => true
   
       belongs_to :department_type
       belongs_to :address, :class_name => "Address", :foreign_key => "address_id"   
       accepts_nested_attributes_for :address,:allow_destroy => true
   end
   

3. Address model

   class Address < ActiveRecord::Base   
       attr_accessible :state, :street1, :street2, :town, :zipcode, :county   
       validate :street1 ,:street2,:town,:state,:county,:zipcode ,:presence => true   
       has_one :department  
   end
   

4. view-page

           <h1 id="form-title">Add New Department</h1>
   
           <%=form_for @department ,:validate=>true do |f|%>   
   <div    id="respond">
