Rails - Mar 2006 - How-to question: form creation / different table update

I could use some direction.

I need a form to collect information on a user''s allergies.  I want to
present them with a form much like the one we fill out when we see a new doc
where you just check-off the things you''re allergic to.  When the form
comes back to the controller I want to add a record to a table for each allergy
they''ve checked.

I was thinking I should create a table with a record for each allergy I need to
present and use that table to generate the form.  But when I get the form back I
don''t want to change the data in the table I used to generate the form,
I want to add data to another table.

Could one of you kind people please point me to documentation / tutorials that
might help?  Any directions are very much appreciated.

Thanks,
Bill

What you''re describing is a look up table and a join table

@allergies = Allergy.find_all()
use that collection to geneate your drop down menu or what ever..

Create a join table allergies_users
and a HABTM relationship in the User and Allergy models

All this is described in the Agile book...
