How to change timestamp of data change in Ruby on Rails

I'm looking to make a timestamp update of when any particular fields are updated in my Ruby on Rails app.

I have a "dprojects" table that has a column for "status" and "status_date".

How can I make it so that if/when the status is updated, the status_date also changes to be the date the status that was most recently updated to?

You can take advantage of ActiveRecord's dirty attribute tracking to set the status date if the status column was changed. Use a before_save callback and then set the status date if needed:

class MyModel < ActiveRecord::Base
  before_save :set_status_date

  def set_status_date
    self.status_date = Time.now if status_changed?
  end
end
