Designing a registration with nested attributes does not create an association

I have User and Account models with has_one association and nested attributes.
My problem is that when registering a user through Devise, no account is created and no error is generated in the log. I am using Rails 3.2 with Devise 2.0.4.


class User
  include Mongoid::Document

  has_one :account, :inverse_of => :user

  accepts_nested_attributes_for :account

  field :name
  validates_presence_of :name
  validates_uniqueness_of :name, :email, :case_sensitive => false
  attr_accessible :name, :email, :password, :password_confirmation, :remember_me, :account_attributes

  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable



class Account
  include Mongoid::Document

  belongs_to :user, :inverse_of => :account

  field :name

  validates_presence_of :user
  attr_accessible :name, :user_id




class RegistrationsController < Devise::RegistrationsController
  def new
    resource = build_resource({})
    respond_with resource



<h2>Sign up</h2>

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>

  <%= f.fields_for :account do |account_form| %>
    <div><%= account_form.label 'Company' %>
    <%= account_form.text_field :name %></div>
  <% end %>


here is my console output

As you can see, I don't see anything about creating an Account . Also verified that the Account collection is not being created by browsing MongoDB. What am I missing? Thank you for your help in advance.

Solved a problem.
I needed to enable: autosave

has_one :account, :inverse_of => :user, :autosave => true


mongoid docs pointed out the problem.

Please note that the autosave option must be enabled for relational associations that use accepts_nested_attributes_for if you do not want to manually save the relationship on update.
