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'

    describe User do

      # Before means this code will run before every test is performed  
      before do
        @user = User.new(name: "Example User", email: "user@example.com",
                         password: "foobar", password_confirmation: "foobar")
      end

      subject { @user }

      it { should respond_to(:admin) }
      it { should respond_to(:authenticate) }
      it { should respond_to(:name) }
      it { should respond_to(:email) }
      it { should respond_to(:password_digest) }
      it { should respond_to(:password) }
      it { should respond_to(:password_confirmation) }
      it { should respond_to(:microposts) } 

      it { should be_valid }
      it { should_not be_admin }

      .
      .
      .
      .

      describe "micropost associations" do

        before { @user.save }
        let!(:older_micropost) do
          FactoryGirl.create(:micropost, user: @user, created_at: 1.day.ago)
        end
        let!(:newer_micropost) do
          FactoryGirl.create(:micropost, user: @user, created_at: 1.hour.ago)
        end

        it "should destroy associated microposts" do
          microposts = @user.microposts
          @user.destroy
          microposts.each do |micropost|
            Micropost.find_by_id(micropost.id).should be_nil
          end
        end

        it "should have the right microposts in the right order" do
          @user.microposts.should == [newer_micropost, older_micropost]
        end
      end
    end

用户.RB

    class User < ActiveRecord::Base
      attr_accessible :name, :email, :password, :password_confirmation
      has_secure_password
      has_many :microposts, dependent: :destroy

      before_save { self.email.downcase! }
      before_save :create_remember_token

      validates :name, presence: true, length: { maximum: 50 }

      VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
      validates :email, presence: true, format: { with: VALID_EMAIL_REGEX },
                uniqueness: { case_sensitive: false }

      validates :password, presence: true, length: { minimum: 6 }
      validates :password_confirmation, presence: true

      private

        def create_remember_token
          self.remember_token = SecureRandom.urlsafe_base64
        end

    end

MICROPOST_SPEC.RB

    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.should raise_error(ActiveModel::MassAssignmentSecurity::Error)
        end    
      end
    end

微邮报

    class Micropost < ActiveRecord::Base
      attr_accessible :content
      belongs_to :user

      validates :user_id, presence: true
      default_scope order: 'microposts.created_at DESC'
    end

工厂.RB

    FactoryGirl.define do
      factory :user do
        sequence(:name)  { |n| "Person #{n}" }
        sequence(:email) { |n| "person_#{n}@example.com"}   
        password "foobar"
        password_confirmation "foobar"

        factory :admin do
          admin true
        end
      end

      factory :micropost do
        content "Lorem ipsum"
        user
      end
    end

最后是我的 GEMFILE：

    source 'https://rubygems.org'

    gem 'rails', '3.2.5'
    gem 'jquery-rails', '2.0.0'
    gem 'bootstrap-sass', '2.0.0'

      gem 'guard-rspec', '0.5.5'
    end

    # Gems used only for assets and not required
    # in production environments by default.
    group :assets do
      gem 'sass-rails',   '3.2.4'
      gem 'coffee-rails', '3.2.2'
      gem 'uglifier', '1.2.3'
    end

    group :production do

    end

感谢您为我提供的任何帮助。

由于您在第 10.1.4 节:micropost中将工厂添加到spec/factories.rb中，因此您在该文件中添加的内容将在您重新启动 Spork 时反映出来。

好像在您的 USER_SPEC.RB 中您丢失了

it { should respond_to(:remember_token) }

我的看起来像这样，它可以工作，测试通过

subject { @user }
it { should respond_to(:admin) }
it { should respond_to(:authenticate) }
it { should respond_to(:name) }
it { should respond_to(:email) }
it { should respond_to(:password_digest) }
it { should respond_to(:password) }
it { should respond_to(:password_confirmation) }
it { should respond_to(:remember_token) }
it { should respond_to(:microposts) }
