Rails超时与Devise签到

Question

在Heroku中运行Rails。其他所有东西似乎都能很好地工作，除了登录时间。

我也可以发布sessions_controller #create，但我只是使用Devise的默认文件。我没有扩展它们或以任何方式改变它们。

这是我的user.rb模型

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

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me
  after_initialize :init

  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable

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

  def init
    self.level ||= 0 if self.level.nil?
  end

end
