ruby-on-rails – rspec用户测试给出“未定义的局部变量或方法`confirmed_at’”

我的rspec测试给了我

NameError:
   undefined local variable or method `confirmed_at' for #<User:0xca6ff98>

我的用户规范是：

require 'spec_helper'

describe User do

    before(:each) do
      @user = Factory(:user)
    end
    # Factory will make sure that in the future if attributes are added the tests below don't break
    # Just as long as the Factory is updated for the new attributes as appropriate.

    context "email is null" do
      it "record is invalid " do
        @user.name = nil
        @user.should_not be_valid
      end
    end

    context "email is unique" do
      it "record is valid " do
        @user2 = Factory(:user)
        @user2 = @user.email
        @user2.should_not be_valid 
      end
    end

end

我找不到对confirmed_at的任何引用

我设计了1.4.8
我的用户迁移是：

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

      # t.encryptable
      # t.confirmable
      # t.lockable :lock_strategy => :Failed_attempts,:unlock_strategy => :both
      # t.token_authenticatable


      t.timestamps
    end

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

  def self.down
    drop_table :users
  end
end

我的用户表是：

解决方法

看起来你错过了路上某处Devise的“可确认”配置.你可以自己添加三个缺失的列或尝试这样的东西(参见Reza.Hashemi在 this thread底部附近的消息：

$rails g migration addconfirmable

然后编辑迁移到此：

def self.up 
  change_table(:users) do |t| 
    t.confirmable 
  end 
end

最后,通常：

$rake db:migrate

我认为上面的过程应该添加你的三列：

> confirmed_at：datetime
> confirmation_token：string
> confirmation_sent_at：datetime

为了你.或者你可以手工完成.
