Hello, I have spent considerable time trying to figure out that which I am about to describe. This included searching Help, consulting my various R books, and trail and (always) error. I have been assuming I would need to use a loop (looping over columns) but perhaps and apply function would do the trick. I have unsuccessfully tried both.

I am running on Rails 2.2.2 on Solaris (and also on my mac) against mysql. For some reason, when I use a select in the partial, the database does not get updated with the changed value.

Hi Chris, Yesterday you kindly submitted an answer to my question on modelling many to many relationships. I''ve briefly tried the proposed solution but so far with no luck. Before I get too involved - I''d like to know if mapping three way :join_tables is "legal" in a Rails sense. I only ask since you put (untested) in your mail and I can''t find any docs on
