Rails easy nested form

Hello i have problem with nested form.. im looking an hour to that and dont know what i forget ..

models/trainer.rb

class Trainer < ActiveRecord::Base
  attr_accessible :telephone, :user_attributes
  has_one :user
  accepts_nested_attributes_for :user
end

models/user.rb

class User < ActiveRecord::Base
  belongs_to :trainer

  attr_accessible :email, :image_url, :name, :password_hash, :password_salt, ...
  attr_accessible :password, :password_confirmation
  attr_accessor :password
  before_save :encrypt_password

  <+ validations ...>

controllers/trainers_controller.rb

  def new
    @trainer = Trainer.new
    @trainer.build_user

    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @trainer }
    end
  end

and i can display new trainer form view (i addedd all user columns as nested) but when i hit CREATE i get

Can't mass-assign protected attributes: user

whats wrong ? thank you

edit: my db schema looks like

[users]
id
trainer_id
name
surname

[trainers]
telephone

Here i uploaded my simplify simple app if anyone was interested :) https://github.com/ScottHiscock/NestedForm

the mistake was in the view, i had

<%= f.fields_for :users do |u| %>

but correct is

<%= f.fields_for :user do |u| %>

Also add user to attr_accessible list of trainer.rb model as follows

attr_accessible :telephone, :user_attributes

or try this

attr_accessible :telephone, :user

Ref accepts_nested_attributes_for

Defines an attributes writer for the specified association(s). If you are using attr_protected or attr_accessible, then you will need to add the attribute writer to the allowed list.

So I think you have to do the following:

class Trainer < ActiveRecord::Base
  attr_accessible :telephone, :user_attributes
