RoR：如何在模型中获取创建时间戳

Question

I have a class Event where I need a method that compares the current date to the date the Event was created. Can you tell me how to access the created_at timestamp the scaffold created for the Event database table?

class Event < ActiveRecord::Base
  attr_accessible :location, :name


  def isInsertedLongAgo
      # current date - insertion date >= 90 days
  end


end

Answer 1

Same as any other attribute - just call it:

def isInsertedLongAgo
  # current date - insertion date >= 90 days
  Time.now - created_at >= 90.days
end

Answer 2

Hi you can acces created at using created_at field self.created_at , At the time of scaffold time stamp is created which create created_at,updated_at You can directly access those variables. replace insertion date with created_at
