Rails4种子失败

Question

Windows8.1 Rails 4.1 Ruby2.0.0

这就是我的user.rb (模型)中的内容：

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable,
         :password_expirable, :confirmable, :lockable, :timeoutable

  if :work_phone != nil
    phony_normalize :work_phone, :default_country_code => 'US'
  end
  if :mobile_phone != nil
    phony_normalize :mobile_phone, :default_country_code => 'US'
  end
  if :fax_phone != nil
    phony_normalize :fax_phone, :default_country_code => 'US'
  end
  if :other_phone != nil
    phony_normalize :other_phone, :default_country_code => 'US'
  end
  validates :first, presence: true
  validates :last, presence: true
  validates :organization, presence: true
  validates_plausible_phone :work_phone
  validates_plausible_phone :mobile_phone
  validates_plausible_phone :fax_phone
  validates_plausible_phone :other_phone
  validates :email, :email => true, presence: true, uniqueness: {case_sensitive: false}
  before_save { |user| user.email = email.downcase }
end

这就是我在我的seeds.rb中所拥有的：

user = User.new(
                :email =>'test@acme.net',
                :password =>'Vb%69Krn#',
                :password_confirmation =>'Vb%69Krn#',
                :first =>'John',
                :last =>'Doe',
                :salutation =>'Doe',
                :organization =>'Doe Test',
                :work_phone =>'555-555-5555',
                :mobile_phone =>'555-555-5555',
                :fax_phone =>'555-555-5555',
                :other_phone =>'555-555-5555',
                :address1 =>'One Main Street',
                :city =>'Anytown',
                :state =>'WA',
                :zip =>'98011',
                :role =>'admin'
                )
user.skip_confirmation!
user.save

当我执行rake db:seed时，会收到以下错误消息：

rake aborted!
NoMethodError: undefined method `password_changed_at_changed?' for #<User:0x00000005f2b458>
C:/projects/rails/doe/db/seeds.rb:27:in `<top (required)>'
-e:1:in `load'
-e:1:in `<main>'
Tasks: TOP => db:seed   

有什么想法吗？

Answer 1

这是扩展的一个问题。您已经设置了password_expirable，但是您可能没有这样做：

create_table :the_resources do |t|
  # other devise fields

  t.datetime :password_changed_at
end
add_index :the_resources, :password_changed_at

正如它在文献资料中所说的那样。
