我安装了ActiveAdmin并使用默认的管理员名称和密码登录,但有一个错误,希望有人可以帮助我.谢谢 !

这是错误:

ArgumentError in ActiveAdmin::Devise::SessionsController#create 
wrong number of arguments (2 for 1)
Rails.root: E:/Ruby/challenger2 - Copy

Application Trace | Framework Trace | Full Trace
app/helpers/sessions_helper.rb:2:in `sign_in'

sessions_helper.rb文件的一部分:

module SessionsHelper
  def sign_in(user)

    self.current_user = user    
  end

  def current_user=(user)
    @current_user = user
  end

  def current_user
    @current_user ||= user_from_remember_token
  end

  def signed_in?
    !current_user.nil?
  end

end
