Question

I got datetime filds order_confirmed_at and completion_confirmed_at

class CoolModel < ActiveRecord::Base
  attr_accessible :order_confirmed, completion_confirmed

  def order_confirmed
    order_confirmed_at.present?
  end

  def order_confirmed=(state)
    if state and order_confirmed_at.blank?
      self.order_confirmed_at = Time.now
    end
    order_confirmed_at.present?
  end

  def completion_confirmed
    completion_confirmed_at.present?
  end

  def completion_confirmed=(state)
    if state and completion_confirmed_at.blank?
      self.completion_confirmed_at = Time.now
    end
    completion_confirmed_at.present?
  end
end

…so in my view I can just check checkbox that order was confirmed and completed

Thing is: not only this is duplication, but this stuff obviously looks pretty standard. So in matter saving me time writing gem: is there rails gem/engine doing this (or maybe part of Rails I’m not aware of) ??

class CoolModel < ActiveRecord::Base
  #something like this 
  acts_even_coller_on :order_confirmed_at, :completion_confirmed_at
end

You could just override the setter method.

def confirmed_at=(value)
  super value == "true" ? confirmed_at || Time.now : nil
end
