ruby-on-rails - 注册时出现Devise Gem错误

Question

使用Devise进行注册时出现错误。我正在从以前设置的基于 session 的身份验证系统切换到Devise。

我安装了Devise并在我的模型中添加了它:

devise :database_authenticatable,  :registerable, :confirmable,
       :recoverable, :rememberable, :trackable, :validatable

这是我的迁移:

class AddDeviseUserTable < ActiveRecord::Migration
  def self.up
    create_table(:users) do |t|
      t.database_authenticatable :null => false
      t.recoverable
      t.rememberable
      t.trackable
      t.confirmable
      t.encryptable

      t.timestamps
    end

    add_column :users, :name, :string

    add_index :users, :email,                :unique => true
    add_index :users, :reset_password_token, :unique => true
    # add_index :users, :confirmation_token,   :unique => true
    # add_index :users, :unlock_token,         :unique => true
    # add_index :users, :authentication_token, :unique => true
  end

  def self.down
    drop_table :users
  end
end

我的 route 也有这个:

root :to => "videos#index"
devise_for :users
resources :users do
  member do
    get :following, :followers
  end
end

我注册时遇到的错误是:

NameError in Devise/registrationsController#create

undefined local variable or method `encrypt_new_password' for #<User:0x1032a8cb8>

为什么会出现此错误？我如何解决它？

Answer 1

Devise源代码中没有encrypt_new_password方法，因此当您从以前的身份验证系统切换到Devise时，我怀疑此方法被遗忘了。我会在您的应用程序代码中搜索字符串encrypt_new_password，然后查看可以找到的内容。

您的用户模型中可能需要更多清理的内容。尤其要在用户模型中查找回调之前和/或之后是否过时，因为失败发生在调用User#save期间。
