我是 RoR 的新手，正在学习 Hartl rails 教程 (http://ruby.railstutorial.org/)。我被困在第 10.1.4 节的测试中，我不断收到以下错误：
失败：
1) 用户微博关联应该销毁相关的微博失败/错误：FactoryGirl.create(:micropost, user: @user, created_at: 1.day.ago) NoMethodError: undefined method content=' for #<User:0x007fce7c86b1e8>
# ./spec/models/user_spec.rb:147:inblock (3 levels) in '
2）用户微博关联应该有正确的微博以正确的顺序失败/错误：FactoryGirl.create（：micropost，用户：@user，created_at：1.day.ago）NoMethodError：未定义的方法content=' for #<User:0x007fce7cbd6288>
# ./spec/models/user_spec.rb:147:in块（3级）在'
由于我是一个新手，我的调试能力相当有限。我相信这不是一个大问题，所以我会很感激我能得到的任何帮助，这是我的代码：
USER_SPEC.RB
require 'spec_helper'

# Before means this code will run before every test is performed
before do

it "should destroy associated microposts" do

微邮报
class Micropost < ActiveRecord::Base
attr_accessible :content

validates :user_id, presence: true

工厂.RB
FactoryGirl.define do
factory :user do

password "foobar"
password_confirmation "foobar"
factory :admin do
admin true

end
factory :micropost do
