ruby-on-rails – 总是通过新安装的Rails Devise获得401未经授权

我有一个新安装的Rails,我正在尝试使用Devise设置身份验证.据我所知,我有一个非常基本的设置应该工作,但是每当我尝试使用默认的Devise登录形式登录时,我会收到一个未经授权的错误.我确信我的证书是正确的,因为我在控制台中创建了一个要测试的用户,如下所示：

User.new({:email=>'mark@markdavies.com.au',:priv_level => 'admin',:password=>'mypassword',:password_confirmation=>'mypassword'}).save

我的用户型号：

class User < ActiveRecord::Base

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

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email,:password,:password_confirmation,:remember_me,:priv_level,:unconfirmed_email
  # attr_accessible :title,:body

  has_one :supplier

end

我的日志：

有什么办法可以获得更多有关Devise失败的信息吗？当我在控制台中创建用户的加密使用不同于通过表单？
