通过 Devise 生成模型不添加字段 - Devise with Mongoid

Question

我按照说明安装了设备。当我做rails generate devise User 时，设计确实生成了 user.rb，但它没有编写设计模块及其必填字段。 它只写在 user.rb 里面

class User
  include Mongoid::Document
end

我以前对另一个应用程序也有同样的想法，对于类似的命令，user.rb 填充了这些：

  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :validatable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :omniauthable

  ## Database authenticatable
  field :email,              type: String, default: ""
  field :encrypted_password, type: String, default: ""

  ## Recoverable
  field :reset_password_token,   type: String
  field :reset_password_sent_at, type: Time

  ## Rememberable
  field :remember_created_at, type: Time

  ## Trackable
  field :sign_in_count,      type: Integer, default: 0
  field :current_sign_in_at, type: Time
  field :last_sign_in_at,    type: Time
  field :current_sign_in_ip, type: String
  field :last_sign_in_ip,    type: String

  ## Confirmable
  # field :confirmation_token,   type: String
  # field :confirmed_at,         type: Time
  # field :confirmation_sent_at, type: Time
  # field :unconfirmed_email,    type: String # Only if using reconfirmable

  ## Lockable
  # field :failed_attempts, type: Integer, default: 0 # Only if lock strategy is :failed_attempts
  # field :unlock_token,    type: String # Only if unlock strategy is :email or :both
  # field :locked_at,       type: Time

我可能做错了什么？我可能跳过了哪一步？我非常感谢您的帮助。 谢谢

如果你使用的是 Rails4，

在您的 Gemfile 中添加这一行

gem 'devise', :git => "git://github.com/plataformatec/devise.git"

然后运行，

bundle update
rails generate devise User

现在可以正常使用了。
