Rails 3 tutorial: problem with rspec + factory_girl_rails

Question

I followed the Rails tutorial (http://railstutorial.org/chapters/beginning, Rails 3 version) and I stopped in chapter 11 when using Factory Girl and Rspec, I have a test that fails, and I feel that I’m doing something wrong, but I don’t see that.
First of all, there is a git repository on Github with code that fails this test. http://github.com/Monomachus/ch3_static_pages

So, I got a user model

class User < ActiveRecord::Base
  attr_accessor :password
  attr_accessible :name, :email, :password, :password_confirmation

  has_many :microposts
  .
  .
  .

I got a microflow model

class Micropost < ActiveRecord::Base
  attr_accessible :content

  belongs_to :user

  default_scope :order => 'microposts.created_at DESC'
end

Then i got factory girl settings

Factory.define :user do |user|
  user.name                  "Michael Hartl"
  user.email                 "[e-mail]"
  user.password              "foobar"
  user.password_confirmation "foobar"
end

Factory.define :micropost do |micropost|
  micropost.content "Foo bar"
  micropost.association :user
end

And finally, the rspec code

require 'spec_helper'

describe Micropost do
    .
    . 
  describe "microposts associations" do

    before(:each) do
      @user = User.create(@attr)
      @mp1 = Factory(:micropost, :user => @user, :created_at => 1.day.ago)
      @mp2 = Factory(:micropost, :user => @user, :created_at => 1.hour.ago)
    end

    it "should have a microposts attribute" do
      @user.should respond_to(:microposts)
    end

    it "should be in the reverse order of appearing" do
      @user.microposts.should == [@mp2, @mp1]
    end
  end
end

And I got an error that definitely tells me that I am doing something wrong.

Answer 1

:) Micropost.

describe "microposts associations" do

  before(:each) do
    @user = User.create(@attr)
    @mp1 = Factory(:micropost, :user => @user, :created_at => 1.day.ago)
    @mp2 = Factory(:micropost, :user => @user, :created_at => 1.hour.ago)
  end

  it "should have a microposts attribute" do
    @user.should respond_to(:microposts)
  end

  it "should be in the reverse order of appearing" do
    @user.microposts.should == [@mp2, @mp1]
  end
end

@attr , , , @user = nil, . , , . :)

, , 100 , Faker ( 10.25 . 390), RubyMine , , ( ). @attr 8 user_spec.rb : email = > "[e-mail]", , ( , Faker ).

@attr 8 "microcopost association" (user_spec.rb) : email = > "[e-mail]". , , n00b.

Update:

, @user = User.create(@attr) @mp1 @mp2.
