Question

我得到了上述错误，但不明白为什么。这是堆栈跟踪：

这是user.rb模型

require 'bcrypt'
require 'dm-validations'

class User
  attr_reader :password
  attr_accessor :password_confirmation

  validates_confirmation_of :password

  include DataMapper::Resource

  property :id, Serial
  property :email, String

  property :password_digest, String, length: 60

  def password=(password)
    @password = password
    self.password_digest = BCrypt::Password.create(password)
  end

end

我尝试使用和不使用＆d.d-validations＆＃39;但它并没有什么区别。

任何帮助都会很棒。
