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:
# assuming trailing commas...
find(:all, :conditions => ["date LIKE '%?,%'", date.strftime("%Y/
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
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...
