Nested form polymorphic

3 models - User, Images, Interests. Everything looks ok but nothing
gets inserted into child models:(

Model code excerpt


User model =>
has_many :interests, :as => :interestible, :dependent => :destroy
accepts_nested_attributes_for :interests, :reject_if => proc {|
attributes| attributes[“name”].blank?}

has_many :images, :as => :imageible, :dependent => :destroy
accepts_nested_attributes_for :images, :reject_if => proc {|

attributes| attributes[“image_file_name”].blank?}

attr_accessible :username, :password, :password_confirmation, :email,
:images_attributes, :interests_attributes


Controller Code


def new
@user = User.new
images = [email protected]}
interests = [email protected]}

    respond_to do |format|
        format.html # new.html.erb
        format.xml  { render :xml => @user }
    end
end

View Code


<% semantic_form_for @user, :html => {:multipart => true} do |form| %>

<% form.inputs do %>
<%= form.input :username, :label => ‘Username’, :input_html =>
