activerecord

I know you can do this with virtual attributes, but what if the column actually exists?

For example, my model has a raw_topic column. When raw_topic is set, I want artist and song_title to be set based off of raw_topic's contents. Ideally, I'd like to override the raw_topic= method, but rails doesn't seem to like that.

What's the proper way of doing this? Is a callback the only way?
