私はレールでルビーを学んでいます。ユーザー情報を保存するためのモデルを作成していますが、 rake db：seedを呼び出すと、次のエラーが発生します。何が欠けているのでしょうか。

rake db:seed

require 'digest'
class User < ActiveRecord::Base
  attr_accessor :password 
  attr_accessible :email, :password
  validates :email, :uniqueness => true, 
                                    :length => {:within => 5..50},
                                    :presence => true

  validates :password, :confirmation => true, :length => { :within => 4..20 }, :presence => true, :if => :password_required?

  has_one :profile

  has_many :articles, :order => 'published_at DESC, title ASC',
                      :dependent => :nullify
  has_many :replies, :through => :articles, :source => :comments

  before_save :encrypt_new_password

  def self.authenticate(email, password)
    user = find_by_email(email)
        return user if user && user.authenticated?(password)
  end

  def authenticated?(password)
    self.hashed_password == encrypt(password)
  end


  def encrypt_new_password
    return if password.blank?
      self.hashed_password  = encrypt(password)                                                                                                                                                                                                                                                                                                                                                                                                                                                              
  end

  def password_required?
    hashed_password.blank? || password.present?
  end

 def encrypt(string)
   Digest::SHA2.hexdigest(string)
 end 

end

に追加する必要がありpassword_confirmationますattr_accessible

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

そしてそれは動作するはずです。

ログに「保護された属性を一括割り当てできません：password_confrimation」と記載されているように、ユーザーモデルにpassword_confrimationを追加する必要があります

attr_accessible：password_confrimation
