I'm having trouble storing the date/time with my comments - I'm getting the MySQL error "posted_at is null". How do I setup my code to automatically store the current date/time in the 'posted_at' column of my 'comments' table?

Rename the column created_at instead of posted_at and this behavior will automatically be turned on (make sure column is DATETIME not TIMESTAMP). Otherwise have a look at this article on how to extend ActiveRecord to use custom "magic" timestamp columns: http:// wiki.rubyonrails.com/rails/pages/ExtendingActiveRecordExample sebastian
