rspec关联创建错误

Question

I have a model item has_many ratings and a ratings belongs_to item ratings belongs_to user I want to force a user who is creating an item to rate it too. Other users can then rate it later on. item and user have no association in my model. I am doing the following in my item_spec which is giving me an error no implicit conversion of Symbol into Integer on line @item = Item.new(name: "Item1", below.

class Item < ActiveRecord::Base
  has_many :ratings, dependent: :destroy, inverse_of: :item
  accepts_nested_attributes_for :ratings, :allow_destroy => true
  validates :name , :length => { minimum: 3 }
  validates :category , :length => { minimum: 3 }
  validates_presence_of :ratings
end

require 'spec_helper'

describe Item do
  before do
    @item =  Item.new(name: "Item1",
                      url: "www.item1.com",
                      full_address: "Item1Address",
                      city: "Item1City",
                      country: "Item1Country",
                      category: "Item1Type",
                      ratings_attributes:  {"rating" => "3", "comment" =>  "Ahh Good"} )
  end

Also using FactoryGirl I am doing something like this

factory :item do
    before_create do |r|
      r.ratings<< FactoryGirl.build(:ratings, item: r )
    end
    name "Item1"
    url "www.Item1.com"
    full_address "Item1Address"
    city "Item1City"
    country "Item1Country"
    category "Item1Category"
  end  

  factory :ratings do
    rating      3
    comment     "Its not that bad"
    user
  end
end

which again is not yeilding the desired result.
can anyone help me solve this problem please.Thanks!

Answer 1

Working Code, now having problem testing some association order, but at least the desired functionality working.

factory :item do
    name "Item1"
    url "www.Item1.com"
    full_address "Item1Address"
    city "Item1City"
    country "Item1Country"
    category "Item1Category"
  end

  factory :ratings, :class => 'Ratings' do
    association :item, factory: :item, strategy: :build
    user
    rating      3
    comment     "Its not that bad"
  end

  factory :item_with_rating, parent: :item do
    ratings {[FactoryGirl.create(:ratings)]}
  end

Here is the spec file

require 'spec_helper'

describe Item do
  before do
    @item =  FactoryGirl.create(:item_with_rating)
  end

  subject { @item }
  it { should respond_to(:name) }
  it { should respond_to(:url) }
  it { should respond_to(:full_address)}
  it { should respond_to(:city) }
  it { should respond_to(:country) }
  it { should respond_to(:category) }
  it { should respond_to(:ratings) }
  it { should_not respond_to(:type) }
  it { should_not respond_to(:user_id) }
  it { should be_valid }

There is no change in the Model file for item
