Hi all! I have a model (Show) than can have an unknown number of dates. And a date can have an unknown number of shows. Making a Date model seems icky, espicially since I would have to probably write a lot of glue code to get the many-many to work easily. I was thinking maybe storing a Marshaled array of Time objects in a text field, but that isn't very clean either... Any Ideas?

The only major concern with is how you're going to efficiently perform queries for shows occurring on particular dates. If you stored the dates as a comma-separated list of strings, you could make these kinds of queries a bit more efficient: class Show def for_date(date) # assuming trailing commas... find(:all, :conditions => ["date LIKE '%?,%'", date.strftime("%Y/ %m/%d")]) end end You're sorta screwed if you want to find shows within a date range though. Also, you have to load and re-save the entire column just to add or remove a date -- this is probably ok if there are less than a hundred dates... Using a many-to-many isn't THAT hard. You get a lot of power with it -- and the amount of glue code you need to write should be minimal. In this case it seems to be the cleaner solution...
