Rails: неправильное количество аргументов (1 вместо 0) для .new

У меня есть эта ошибка, когда я пытаюсь создать объект обзора:

ArgumentError in ReviewsController#create

wrong number of arguments (1 for 0)

app/controllers/reviews_controller.rb:17:in `new'
app/controllers/reviews_controller.rb:17:in `create'

Я не понимаю, что я делаю не так? Я могу создавать любые другие объекты, но эти выдают эту ошибку, что бы я ни делал. Я стараюсь не приводить никаких аргументов, но все же считаю, что он есть...

Моя модель Review :

# -*- encoding : utf-8 -*-
class Review < ActiveRecord::Base

  attr_accessible :global_validation_date, :hr_comment, :hr_validate, :hr_validator, :manager_comment, :manager_validate, :manager_validation_date, :manager_validator, :owner_satisfaction, :owner_validate, :owner_validation_date, :send, :user_id

  belongs_to :user
  has_many :review_projects, dependent: :destroy

end

Мой контроллер ReviewsController :

# -*- encoding : utf-8 -*-
class ReviewsController < ApplicationController

  before_filter :authenticate_user!
  before_filter :check_permissions, only: :create

  def index
    @user = User.find(params[:user_id])
    @reviews = @user.reviews
  end

  def create
    @user = User.find(params[:user_id])
    @reviews = @user.reviews
    if @reviews.empty? || check_last_validate

      @review = Review.new   # HERE IS MY ERROR

      if @review.save
        render 'index', notice: "Review successfully created"
      else
        render 'index', notice: "An error occured on saving, please try again"
      end
    else
      render 'index', alert: "You have to validate previous review before create a new one."
    end

    redirect_to user_reviews_path
  end

  private

  def check_permissions
    render_access_forbidden unless current_user == User.find(params[:user_id])
  end

  def check_last_validate
    if [email protected]?
      return (@reviews.last.hr_validate || @reviews.last.manager_validate)
    else
      return false
    end
  end

end

Я прочитал все те же вопросы на SO, но ничего не работает. Я осторожен с опечатками, но я не думаю, что сделал ошибку.

Я попробовал три способа создать свой объект Review :

@review = Review.new
@review.user_id = current_user.id
@review.hr_validator = ((current_user.hr_id.nil?) ? current_user.id : current_user.hr_id )
@review.manager_validator = ((current_user.manager_id.nil?) ? current_user.id : current_user.manager_id )
@review.hr_validate = false
@review.manager_validate = false
@review.owner_validate = false
@review.hr_comment = ""
@review.manager_comment = ""
@review.owner_satisfaction = nil
@review.send = false

@review = Review.new(
  user_id: current_user.id,
  hr_validator: ((current_user.hr_id.nil?) ? current_user.id : current_user.hr_id ),
  manager_validator: ((current_user.manager_id.nil?) ? current_user.id : current_user.manager_id ),
  hr_validate: false,
  manager_validate: false,
  owner_validate: false,
  hr_comment: "",
  manager_comment: "",
  owner_satisfaction: nil,
  send: false )

@user.reviews.create!(
  user_id: current_user.id,
  hr_validator: ((current_user.hr_id.nil?) ? current_user.id : current_user.hr_id ),
  manager_validator: ((current_user.manager_id.nil?) ? current_user.id : current_user.manager_id ),
  hr_validate: false,
  manager_validate: false,
  owner_validate: false,
  hr_comment: "",
  manager_comment: "",
  owner_satisfaction: nil,
  send: false )

Последний дает мне ту же ошибку, за исключением:

wrong number of arguments (2 for 0)

Моя рубиновая версия — 1.9.3, моя версия рельсов — 3.2.13.

Спасибо.

Когда я пытаюсь использовать в своей консоли rails этот код:

current_user = User.first # as you are inside rails console you wont have current_user available to you
@review = Review.new(user_id: current_user.id,
                    hr_validator: ((current_user.hr_id.nil?) ? current_user.id : current_user.hr_id ),
                    manager_validator: ((current_user.manager_id.nil?) ? current_user.id : current_user.manager_id ),
                    hr_validate: false,
                    manager_validate: false,
                    owner_validate: false,
                    hr_comment: "",
                    manager_comment: "",
                    owner_satisfaction: nil,
                    send: false )
@review.save

Я получаю эту ошибку:
