Thank you for your reply,
I have changed my association because what you say makes total sense
however I'm still getting the same error.
I'm starting to think that the accepts_nested_attributes is broken.
I now have in my models.
class User < ActiveRecord::Base
named_scope :find_administrators, :joins => :administrator
has_one :administrator,
:dependent => :destroy
has_many :user_roles,
:dependent => :destroy
has_many :addresses,
:through => :user_roles,
:source => :addresses,
:foreign_key => :contact_id,
:dependent => :destroy
accepts_nested_attributes_for :addresses, :allow_destroy => true
...
end
class UserRole < ActiveRecord::Base
has_many :addresses, :foreign_key => :contact_id,
:dependent => :destroy
has_many :emails, :foreign_key => :contact_id,
:dependent => :destroy
belongs_to :user
accepts_nested_attributes_for :addresses, :allow_destroy => true
end
class Address < ActiveRecord::Base
belongs_to :user_role, :foreign_key => :contact_id
validates_presence_of :contact_id
validates_presence_of :house
end
class Administrator < UserRole
#To do - Move this to a boolean flag on the user_role table.
has_one :site_contact, :foreign_key => :user_role_id
end
Relevant controller methods
class Admin::UsersController < Admin::HomeController
# GET /users/1/edit
def edit
@user = User.find(params[:id])
end
# PUT /users/1
# PUT /users/1.xml
def update
logger.debug("#### update params = #{params}")
@user = User.find(params[:id])
respond_to do |format|
if @user.update_attributes(params[:user])
flash[:notice] = "#{show_user_type} was successfully updated."
format.html { redirect_to([:admin, @user]) }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => @user.errors, :status =>
:unprocessable_entity }
end
end
end
