Rails - Oct 2005 - habtm updates

im using a <select multiple> box where all the many-many values
(which are stored in a join table eg  table1_table2) can be changed.

is there a clean and simple helper to delete the records that are  
excluded from the box,
keep the ones that are there, and add new ones.

I don''t know of any that work with a single select box.  However, the
habtm scaffolding on
http://wiki.rubyonrails.com/rails/pages/HowToExtendScaffolding does
something similar with two select boxes.  You may want to look at the
code on that page and adapt it to work with a single select box.
