To get a table's updated time Ruby on Rails

I have a column with name points in my Users table. Is there any simple way to get the date and time at which this column for a particular user was updated in Ruby on Rails.

Add one more column points_update_at in User table and add call back 

before_update {|u|
 points_update_at = Time.now if u.points_changed?
}

No, you can check updated_at but it will change after any update on record.

Only good solution to that problem is to add another column, let's call it points_updated_at and add a callback to change it value if points is changed.

before_save do
  self.points_updated_at = Time.now if self.points_changed?
end
