NoMethodError在Devise::RegistrationsController#create中用于#<User:0x007fd83f5ccb68>的未定义方法`confirmation_sent_at=‘

Question

我对Rails很陌生。我正在使用设计添加认证和电子邮件确认注册后。当我在本地运行代码时，我会得到标题中的错误消息。我查看过类似的帖子，尝试运行rake db:reset并重新启动服务器。

我将:confirmable添加到models/user.rb中

class User < ActiveRecord::Base devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :confirmable end

错误消息突出显示了这段代码，并特别将以match ?开头的代码行调用为第433行。

else match = match_attribute_method?(method.to_s) match ? attribute_missing(match, *args, &block) : super end end

Completed 500 Internal Server Error in 327ms (ActiveRecord: 0.5ms)

NoMethodError (undefined method `confirmation_sent_at=' for #   <User:0x007fd21e2ebce0>):
 activemodel (4.2.3) lib/active_model/attribute_methods.rb:433:in `method_missing'
 devise (3.5.2) lib/devise/models/confirmable.rb:240:in `generate_confirmation_token'
 activesupport (4.2.3) lib/active_support/callbacks.rb:430:in `block in make_lambda'
 activesupport (4.2.3) lib/active_support/callbacks.rb:143:in `call'

我很感激你的帮助！

添加了迁移文件

class DeviseCreateUsers < ActiveRecord::Migration
  def change
    create_table(:users) do |t|
      ## Database authenticatable
      t.string :name
      t.string :email,              null: false, default: ""
      t.string :encrypted_password, null: false, default: ""

      ## Recoverable
      t.string   :reset_password_token
      t.datetime :reset_password_sent_at

      ## Rememberable
      t.datetime :remember_created_at

      ## Trackable
      t.integer  :sign_in_count, default: 0, null: false
      t.datetime :current_sign_in_at
      t.datetime :last_sign_in_at
      t.string   :current_sign_in_ip
      t.string   :last_sign_in_ip

      ## Confirmable
      t.string   :confirmation_token
      t.datetime :confirmed_at
      t.datetime :confirmation_tokention_sent_at
      t.string   :unconfirmed_email # Only if using reconfirmable

      ## Lockable
      # t.integer  :failed_attempts, default: 0, null: false # Only if lock strategy is :failed_attempts
      # t.string   :unlock_token # Only if unlock strategy is :email or :both
      # t.datetime :locked_at

      t.timestamps null: false
    end

    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
  end
end

@魔杖制造者是正确的。代码应该反映confirmation_sent_at而不是confirmation_tokention_sent_at。

我必须采取的其他步骤是删除我的schema.rb文件，运行rake db:reset，然后运行rake db:migrate来创建更新的(并更正) schema.rb。
