I need to add timestamps (created_at & updated_at) to an existing table. I tried the following code but it didn\'t work.

I made a simple function that you can call to add to each table (assuming you have a existing database) the created_at and updated_at fields:

  # add created_at and updated_at to each table found.
  def add_datetime
    tables = ActiveRecord::Base.connection.tables
    tables.each do |t|
      ActiveRecord::Base.connection.add_timestamps t  
    end    
  end
