How can I set one of my database table to created_at as default value. I did this but didn't work, I have checked in the DB and the value of code is null.
class CreateEvents < ActiveRecord::Migration
def change
create_table :events do |t|
t.string :title
t.string :location
t.text :description
t.date :occurs_on
t.string :code, :default => Event::created_at
t.timestamps
end
end
end
