提前致谢

模型

admin_user.rb

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

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email,:password,:password_confirmation,:remember_me,:id,:admin_permission
  # attr_accessible :title,:body
  has_one :admin_permission
  validates_uniqueness_of :email

  def self.current_logged_user
    # ?
  end
end

UPDATE

当我尝试在dashboard.rb或任何活动的管理相关文件中使用方法’current_user’,显然没有实现.

OUTPUT

undefined local variable or method `current_user' for
