私は Ruby on Rails の初心者であり、Michael Hartl の Rails チュートリアルを進めています。第 10 章 (具体的には、10.1.3「ユーザー/マイクロポストの関連付け」) で修正できないように見えるバグに遭遇しました。次の rspec コマンドを実行すると、エラーが発生します。
$ bundle exec rspec スペック/モデル
次のエラーが発生します。

これは micropost_spec.rb のコードです:
require 'spec_helper'
describe Micropost do
let(:user) { FactoryGirl.create(:user) }
before { @micropost = user.microposts.build(content: "Lorem ipsum") }
subject { @micropost }
it { should respond_to(:content) }
it { should respond_to(:user_id) }
it { should respond_to(:user) }
its(:user) { should == user }
it { should be_valid }
describe "when user_id is not present" do
before { @micropost.user_id = nil }
it { should_not be_valid }
end
describe "accessible attributes" do
it "should not allow access to user_id" do
expect do
Micropost.new(user_id: user.id)
end.to raise_error(ActiveModel::MassAssignmentSecurity::Error)
end
end
end

マイクロポスト.rb...
class Micropost < ActiveRecord::Base
attr_accessible :content
belongs_to :user
validates :user_id, presence: true
end
