未定义的方法'password=' for＃<User：0xb88ac38>

我正在使用http://ruby.railstutorial.org/chapters/user-microposts#code:sample_microposts教程构建Micropost模型 . 在运行测试以验证微博对象响应内容和user_id属性时，我得到此错误未定义方法'password=' for＃下面是"User.rb"＆"Micropost spec.rb"的代码块 .

**User.rb**

  class User < ActiveRecord::Base
    has_many :arts
    belongs_to :account
     attr_accessible :name, :email,:password, :password_confirmation

       has_many :microposts, dependent: :destroy
    has_many :relationships, foreign_key: "follower_id", dependent: :destroy
       has_many :followed_users, through: :relationships, source: :followed
    has_many :reverse_relationships, foreign_key: "followed_id",
                                   class_name:  "Relationship",
                                   dependent:   :destroy
      has_many :followers, through: :reverse_relationships, source: :follower

     def following?(other_user)
    relationships.find_by_followed_id(other_user.id)
     end

      def follow!(other_user)
    relationships.create!(followed_id: other_user.id)
    end

     def unfollow!(other_user)
      relationships.find_by_followed_id(other_user.id).destroy
    end
        def accountName
        account.name

• Micropost_spec*

需要'spec_helper'

describe Micropost do

  let(:user) { FactoryGirl.create(:user) }
  before do
    # This code is wrong!
    @micropost = Micropost.new(content: "Lorem ipsum", user_id: user.id)
  end

  subject { @micropost }

  it { should respond_to(:content) }
  it { should respond_to(:user) }

end

Migration Users

class CreateUsers <ActiveRecord :: Migration def change create_table：users do | t | t.string：name t.string：category t.timestamps
最终结束

User Model

class User <ActiveRecord :: Base has_many：arts belongs_to：account has_secure_password attr_accessible：name，：email has_many：microposts before_create {generate_token（：auth_token）}
has_many：microposts，dependent :: destroy has_many：relationships，foreign_key：“follower_id”，dependent :: destroy
has_many：followed_users，::: relationships，source ::: follow has_many：reverse_relationships，foreign_key：
“followed_id”，class_name：“关系”，依赖:: destroy has_many：followers，through :: reverse_relationships，source :: follower def generate_token（column）begin self [column] = SecureRandom.urlsafe_base64 end而User.exists？（column = > self [column]）def def？（other_user）
relationships.find_by_followed_id（other_user.id）结束
def follow！（other_user）relationships.create！（follow_id：other_user.id）end def unfollow！（other_user）relationships.find_by_followed_id（other_user.id）.destroy end def accountName account.name end end end
